Sandboxing Technology for Email

by Jennifer Marsh | Nov 20, 2023 | Network Security, Spam Software |

Implementing your own sandboxing technology for email can be complex and costly. SpamTitan Email Security has an inbuilt sandbox, so all the hard work is done for you. You get the full cybersecurity benefits of a sandbox at a very low cost.

What are the Benefits of an Email Sandbox?

Email sandboxing is no longer a ’want’ it is now a ‘must-have.’ Cybercriminal groups are conducting huge numbers of attacks, nation-state actors are targeting businesses to steal their proprietary data, and these attacks are getting far more sophisticated and can easily evade standard security solutions. The consequences of a successful cyberattack are severe. IBM’s 2023 Cost of a Data Breach Report indicates that the average cost of a successful attack and data breach has risen to $4.45 million in the United States. It is no surprise that many small to medium-sized businesses fold within 6 months of a successful attack.

As has been the case for many years, one of the easiest ways to gain initial access to a company’s network is via email. Employees are targeted as they can be tricked into disclosing their credentials or installing malware. Email security solutions such as spam filters and secure email gateways are capable of blocking many threats, but they are failing to block zero-day malware threats. Traditional email security solutions are reliant on signature-based detection methods for blocking malware. When a malware threat is detected and analyzed by security researchers, the signature for that malware variant is added to the definition list. Email security solutions use signature-based detection methods to block 100% of known malware.

The problem comes with new malware, for which no signature has been defined. Without a signature, malware will not be identified as malicious if it is encountered. If a novel malware variant is attached to an email, the email will most likely be delivered and can be opened by an end user and new malware variants are now being released at an incredible rate. While signature-based detection has served businesses well, additional protection is now required – email sandboxing.

With an email security solution that has an email sandbox, inbound messages will first be subjected to standard checks. An email sandbox is then used to safely analyze the behavior of files in an environment where no harm can be caused. If malware is executed, it will be detected based on its behavior rather than a signature. The threat will then be blocked, and no harm will be caused.

SpamTitan Email Sandboxing Technology for Email

With SpamTitan, the initial checks include AI-based and machine-learning detection, which is capable of detecting previously unseen phishing threats. All attachments are scanned with two antivirus engines to ensure 100% of known malware threats are detected and blocked. The sandbox provides an extra layer of protection. When initial checks are passed, suspicious messages are sent to the sandbox for deep analysis. File attachments are safely detonated, their behavior is analyzed, and the results are checked against an extensive array of online repositories. The process usually takes just a few minutes, or in some cases, a maximum of 20 minutes.

If a threat is detected it is reported to the Bitdefender Global Protective Network – Bitdefender’s cloud threat intelligence service. If that threat is detected again by SpamTitan or any device connected to the network, it will not need to be sent to the sandbox again and all devices will be protected against that threat. The latest malware variants often include code that checks for running security solutions and whether it has landed on a real endpoint. If a virtual environment is detected and the malware determines it is in a sandbox, it will not perform its malicious actions and may delete itself to prevent analysis. To get around this, the email sandbox emulates a real endpoint and analyzes files by leveraging purpose-built, advanced machine-learning algorithms. The sandbox incorporates anti-evasion and anti-exploit techniques and performs aggressive behavior analysis. Every evasion attempt by malware is properly marked and the files are flagged.

The sandbox analyzes a broad range of targets, including documents, spreadsheets, and executable files, and is capable of identifying and blocking polymorphic malware and other threats that have been developed for undetectable attacks. With email-based cyberattacks increasing in number and sophistication, businesses need to ensure they have advanced defenses. With SpamTitan sandboxing technology for email you get advanced threat protection at an affordable price.

What is Sandboxing in Cybersecurity?

by Jennifer Marsh | Nov 15, 2023 | Network Security, Spam Software |

What is Sandboxing in Cybersecurity?

Sandboxing in cybersecurity terms refers to an isolated virtual machine that is used for testing code and analyzing files. Since the sandbox is isolated from other systems and networks, unverified code, untested programs, email attachments, and files downloaded from the Internet can be executed or detonated safely. Code is executed and files are opened and their behavior is analyzed to determine if they are safe or if they may cause damage to data or systems. In the sandbox, the activities that can be performed are restricted so they can’t cause any real damage. If code is executed in the sandbox and it is determined to be malicious, it will be deleted or quarantined for further analysis. Sandboxing is also used for checking URLs. For instance, some web browsers will first open a URL in a sandbox where permissions are set to the lowest privilege levels. If any attempt is made to perform an action that is not permitted, access to the URL will either be blocked or the user will receive a warning.

Why is Sandboxing Important?

In software development, new code may have unintended consequences, such as causing other systems to malfunction, which in a production environment could cause unacceptable and costly downtime. A sandbox allows code to be fully tested to ensure it is safe. A security sandbox protects against malicious code that has been deliberately written to cause damage and/or provide access to systems and data. For example, ransomware is malicious code that encrypts files to prevent them from being accessed. A threat actor then demands payment for the keys to decrypt files. If that code was allowed to execute on the network, data could be permanently lost, or a ransom would need to be paid to recover files.

Cyberattacks on businesses have been increasing and are now being conducted more frequently than ever before. The average ransom demand in data theft and ransomware attacks is now more than $1.5 million, and data from Rapid7 suggests more than 1,500 organizations fell victim to ransomware attacks in the first half of 2023, with more than 20 new ransom groups emerging. Cybercriminals also still use backdoors, keyloggers, banking trojans, and information stealers to gain access to networks and steal sensitive data. To make matters worse, new malware and ransomware variants are constantly being released and these evade security solutions that rely on signature-based detection. It is vital that all files and applications are thoroughly tested before being allowed anywhere near the network and sandboxing allows even previously unseen malicious files to be identified and neutralized.

Email Sandboxing

Email security solutions often use sandboxing for attachments and URLs. With email attachments, they will first be scanned using standard anti-virus engines to determine if they contain known malware or malicious code. These AV checks will only detect known malware. New malware variants that have not been encountered before cannot be detected, as standard AV solutions search for signatures of known malware. Email sandboxing is used to detect new malware, often referred to as zero-day threats. Files that are determined to be clean after AV scanning are sent to the sandbox for behavioral analysis. Email security solutions may also use a sandbox for testing embedded URLs in messages and will follow the links and check the destination and assess whether it contains any threats.

Advantages and Disadvantages of Email Sandboxing

by Jennifer Marsh | Nov 10, 2023 | Network Security, Spam Software |

Sandboxing is the use of a virtual environment for testing code and safely opening untrusted files. The sandbox is an isolated and secure environment that emulates a legitimate endpoint; however, there are no connections to the business network, the sandbox environment contains no real data, and if dangerous code is executed, no harm will be caused.

Advantages of Email Sandboxing

Sandboxing is important because of the sheer number and complexity of threats faced by businesses. Cybercriminal groups are conducting increasing numbers of attacks, new groups are constantly being formed, and their attacks are becoming much more sophisticated. The cost of these attacks and the resultant data breaches are also spiraling. According to the 2023 Cost of a Data Breach Report from IBM, on average, data breaches cost $4.45 million to resolve in the United States and $10.93 million for a healthcare data breach.

Many of these threats come from email. Emails are used to send attachments containing malicious code that downloads malware that provides a cyber actor with access to the network. Links to malicious websites are also distributed via email where malware is downloaded. While businesses have a degree of protection if they have anti-virus software installed, most anti-virus solutions can only detect known malware variants – Malware that has previously been analyzed and had its signature added to the solution’s malware definition list. Antivirus solutions will not detect new malware variants nor fileless malware, which is executed in the memory with no files downloaded to the disk.

Sandboxing provides an additional layer of protection against zero-day malware and ransomware attacks and will allow malicious files to be identified, detected, and quarantined before they can do any harm, even if they have not previously been encountered. In the sandbox, malware is identified by the actions it tries to perform, not by any signature.

Disadvantages of Email Sandboxing

While there are clear benefits, there are some disadvantages of email sandboxing. Businesses may want to add email sandboxing to their cybersecurity arsenal, but email sandboxes can be complicated to set up and run, and they can require a considerable amount of resources and can be expensive to run. Another of the disadvantages of email sandboxing is analyzing file attachments takes time and messages cannot be delivered until all checks have been performed. It is therefore inevitable that there will be email delivery delays.

As with any cybersecurity solution, there is the potential for false positives. An email attachment may be determined to be malicious when it is actually harmless. In such cases, important business emails may be blocked or deleted. The last main disadvantage is malware often contains code that determines if it has landed on the targeted endpoint or if it is in a virtual environment. If the latter is detected, the malware may delete itself or not perform any of its programmed malicious actions. Considering the cost of a successful cyberattack, the advantages of email sandboxing outweigh the disadvantages, provided the right sandboxing solution is chosen.

SpamTitan Email Security with Sandboxing

SpamTitan is an award-winning email security solution from TitanHQ that provides advanced threat protection at an affordable price.

Malicious File Sandbox for Email

by Jennifer Marsh | Nov 5, 2023 | Network Security, Spam Software |

Multiple layers of security are required to protect against increasingly sophisticated email attacks. A malicious file sandbox for email should be one of those layers to ensure your business is protected against zero-day and stealthy malware threats.

Email: The Most Common Initial Access Vector Used by Cybercriminals

There are many ways that cybercriminals can attack businesses, but email is the most common initial access vector. Most employees have email accounts which means they can be easily reached, and social engineering techniques are used to trick employees into opening malicious attachments or visiting links in emails. Cybercriminals have become adept at exploiting human weaknesses in defenses.

One of the main aims of email campaigns is to deliver malware to provide persistent access to victims’ networks. Executable files may be attached to emails and hidden using double file extensions to make the files appear to be legitimate documents, PDF files, or spreadsheets. Office files may be attached that have malicious macros which, if allowed to run, trigger the download of a first-stage malware payload. The problem for businesses is these campaigns are becoming much more sophisticated, they often bypass standard email security defenses, and they land in inboxes where they can be opened by employees.

Defending against sophisticated email attacks requires a defense-in-depth approach, which should include a spam filter/secure email gateway, a web filter, multifactor authentication, an endpoint detection and response solution, and security awareness training for employees. To improve protection further and defend against new and stealthy malware threats, it is important to have a malicious file sandbox for email.

What is a Malicious File Sandbox?

A malicious file sandbox is an isolated virtual environment where untrusted, suspicious files can be detonated securely without risking network or data security. The sandbox is used for analyzing emails, documents, application files, and other executable files to determine their true nature. When an email is received, it must first pass through a spam filter which looks for the common signatures of spam and phishing emails, performs reputation checks on the sender, analyzes the message content, and scans email attachments using antivirus software. The spam filter will filter out the majority of spam and phishing emails and all known malware variants using the antivirus software.

The problem is many email attacks are stealthy and have been developed to be undetectable, and cyber actors are skilled at getting their emails past email defenses and into inboxes. One way this is achieved is by using polymorphic malware, which cannot be detected by standard email security solutions and antivirus software. A malicious file sandbox is needed to protect against these novel threats.

When suspicious files are received that pass the front-end checks, they are sent to the sandbox for in-depth analysis of their behavior. The malicious file sandbox is configured to look like a real target environment to ensure that when an email is sent to the sandbox any malware acts as it would in the wild and is tricked into determining that it has landed on the endpoint of its intended target. No harm can be caused in the sandbox as the environment is isolated and not set up locally. If malware is detected, a report is generated of any malicious intent or unexpected actions, and actionable insights are provided to allow the threat to be blocked.

The SpamTitan Malicious File Sandboxing Service

SpamTitan is an award-winning anti-spam and anti-phishing solution from TitanHQ that is used by thousands of businesses and managed service providers to protect against email-based attacks. The solution leverages artificial intelligence and machine learning algorithms to detect novel threats and predict new attacks, reputation checks are conducted using SPF, DKIM, and DMARC, users are protected from malicious links in emails, and the solution has dual antivirus engines that scan for known malware.

SpamTitan also includes a Bitdefender-powered malicious file sandbox for blocking zero-day malware threats. The sandbox analyzes a broad range of targets, including emails, documents, application files, and other executable files, and leverages purpose-built, advanced machine-learning algorithms, aggressive behavior analysis, anti-evasion techniques, and memory snapshot comparison to detect sophisticated threats and delivers advanced threat protection and zero-day exploit detection. The sandbox also extracts, analyzes, and validates URLs within files.

The sandbox is not located on the endpoint so there are no performance implications, and strong machine learning and behavior detection technologies ensure that only files that require further analysis are sent to the Sandbox. If a malicious file is detected, the sandbox informs Bitdefender’s cloud threat intelligence service to ensure the threat is instantly blocked globally and will not need to be set to the sandbox for analysis again. The sandbox allows businesses to identify and block malicious files such as polymorphic malware and other threats that have been developed for use in undetectable attacks.

The SpamTitan malicious file sandbox delivers best-in-class detection, advanced anti-evasion technologies, innovative pre-filtering, and MITRE ATT&CK framework support. If you want the best protection from dangerous malware, you need a malicious file sandbox for email, and with SpamTitan you get that and more at a very affordable price.

Quishing: The Fast-Growing Phishing Trend

by Jennifer Marsh | Oct 31, 2023 | Phishing & Email Spam, Spam Advice |

What is Quishing?

Quishing is a fast-growing phishing trend involving QR codes, which are now used in more than one-fifth of phishing attacks. QR Codes, or Quick Response codes to give them their full name, have become a popular way of communicating information, most commonly URLs for websites and PDF files. QR codes were originally developed and used for tracking parts in manufacturing, but their uses have grown considerably and QR codes are now everywhere.

They are also used by restaurants for directing diners to their menus – something that became more common during the COVID-19 pandemic as a way of reducing the risk of virus transmission as well as reducing costs by not having to print menus. They are used by advertisers at bus stops and train stations, in magazines and printed pamphlets, and even TV commercials. They allow advertisers to get smartphone users to quickly and easily visit a website to find out more about products and services and make a purchase.

The ubiquity of QR codes and how they have been embraced by consumers, coupled with the difficulty of distinguishing between a benign and useful QR code and a malicious one has made them perfect for malicious actors for driving traffic to their malicious websites. QR codes are sent via emails, instant messaging services, and on social media sites and direct users to a malicious website where credentials are harvested or malware is downloaded. Another key benefit of QR codes is they are read by smartphones, rather than laptops or desktop computers. Smartphones are far less likely to have security software installed that can detect either the phishing message or the malicious URL that users are directed to.

Malicious actors have embraced QR codes and commonly use them in phishing campaigns. One analysis of phishing emails revealed 22% of phishing emails intercepted in October 2023 used QR codes, many of which used standard phishing lures to get users to scan the QR code, such as a security alert requiring immediate action. Other types of quishing attacks have exploited the “login with QR Code” feature that is now used by apps and websites as a secure way of logging in. In this type of attack, termed QRLJacking, the attacker initiates a client-side QR session of the targeted app or website, and clones the login QR code to display a fake but realistic clone of the targeted app. Social engineering techniques are used to send a user to that page, the user scans the malicious QRL using the mobile application the QRL code was created for, and the attacker gains access to the victim’s account. The app is unaware this is fraudulent access and provides the user’s data to the attacker.

Protecting against these attacks is much harder than protecting against standard phishing attempts since security solutions struggle to detect these malicious QR codes. That said, protecting against QRLJacking is simple. Don’t ever use QRLs for logging in. Avoiding other quishing attacks involves similar advice. Avoid using QR codes entirely, or at least avoid using QR codes from untrusted sources. If a QR code is received via email, the source of the email needs to be verified, and even then it is best to avoid using it and just visit the website of the company that claims to have sent it.

Companies should also consider adding quishing to their security awareness training programs given how commonly QR codes are being used in phishing. That’s easy to do with the SafeTitan Security Awareness Training Platform – just choose the Quishing content and add it to your training program and incorporate the quishing templates into your phishing simulations.

Has AI Surpassed Humans at Writing Phishing Emails?

by Jennifer Marsh | Oct 29, 2023 | Phishing & Email Spam, Spam News |

Has AI surpassed humans at writing phishing emails? A team of researchers at IBM decided to put that to the test and the results are now in. Humans still have the edge, but AI is not far behind and will soon overtake humans.

There has been a lot of press coverage recently about the capabilities of AI and significant concern has been voiced about the threat AI-based systems pose. While there are legitimate concerns that AI systems could turn against humans, one of the most pressing immediate cybersecurity concerns is that cybercriminals could use generative AI tools to devastating effect in their cyberattacks.

Many security researchers have demonstrated that generative AI chatbots such as ChatGPT can write perfect phishing emails, free of spelling mistakes and grammatical errors, and can also create convincing lures to trick humans into opening a malicious email attachment or visiting a malicious website. ChatGPT and other generative AI tools can also be used to write malware code, and there have been demonstrations of AI tools being used to create functional polymorphic malware and ransomware code. One of the key advantages of AI tools such as ChatGPT is the speed at which phishing emails, social engineering lures, and malware code can be generated, which could greatly improve the efficiency and even the quality of a range of malicious campaigns.

Tools such as ChatGPT have guardrails in place to prevent them from being used for malicious purposes such as writing malware or phishing emails. If you ask ChatGPT to write ransomware code or a phishing email, it will refuse to do so as it violates OpenAI’s terms and conditions of use. Those controls can, however, be easily bypassed, plus there are generative AI tools that have been developed specifically for cybercriminal use, such as WormGPT and FraudGPT.

Are Cybercriminals Using AI in Their Campaigns?

Security researchers have shown that it is possible to use generative AI tools for offensive cybersecurity purposes, but are cybercriminals actually using these tools? While there is limited evidence on the extent to which these tools have been used, it is clear that they are being put to use. An August 2023 report by the U.S. cyber defense and threat intelligence firm Mandiant explored this and found threat actors are certainly interested in generative AI but use remains limited. The main area where these AI tools are being used is in information operations, specifically to efficiently scale their activity beyond their inherent means and to produce more realistic content.

Financially motivated threat actors have been using generative AI such as deepfake technology to increase the effectiveness of their social engineering, fraud, and extortion operations, including the use of face swap tools. The main focus currently is on social engineering, such as phishing attacks, for generating convincing lures for phishing emails and greatly reducing the time spent researching potential targets.

Are Generative AI Tools Better than Humans at Phishing?

An IBM X-Force team of social engineering experts recently went head-to-head with a generative AI chatbot to see which was better at creating phishing emails. The researchers would typically take around two days to construct a phishing campaign, with most of the time taken on researching targets to identify potential social engineering lures, such as topics for targeting specific industries, the persons to impersonate, and for creating convincing emails.

They developed 5 simple prompts to get a generative AI chatbot to do this, and the entire campaign was created in just 5 minutes, thus saving a cybercriminal around 2 days of their time. The good news is that the security researchers’ email performed better in terms of a higher click rate and a lower reporting rate, but the margins were very small. Humans still have the edge when it comes to emotional manipulation in social engineering, but AI is not very far behind and is likely to overtake humans at some point.

How to Combat AI-generated Phishing

Generative AI can save cybercriminals a great amount of time and the content generated is almost as good as human-generated content, and certainly good enough to fool many users. The best defense is to provide more extensive and regular security awareness training to employees to improve resilience to phishing attempts and to put cybersecurity solutions in place that incorporate AI and machine learning tools.

TitanHQ’s Email Security solution, SpamTitan, has AI and machine learning capabilities that are used to detect previously unseen phishing threats, such as those generated by AI tools. These capabilities also apply to email attachments, which are sent to an email sandbox for deep analysis of their behavior, allowing SpamTitan to detect and block zero-day malware threats. TitanHQ can also help with security awareness training. SafeTitan is an easy-to-use security awareness training and phishing simulation platform that has been shown to reduce susceptibility to phishing by up to 80%. Combined with multifactor authentication and endpoint detection tools, these solutions can help organizations improve their defenses against cyberattacks that leverage generative AI.

What is Message Sandboxing?

by Jennifer Marsh | Oct 28, 2023 | Spam Advice, Spam Software |

Message sandboxing is a security feature of spam filters, secure email gateways, and other email security solutions where inbound messages are sent to a secure and isolated environment where the messages are subjected to behavioral analysis. File attachments are detonated and analyzed for malicious properties and actions, such as attempted file downloads from the Internet, command-and-control center callbacks, and attempts to write code to the memory.

What is a Sandbox?

In the technology sense, a sandbox is a contained virtual environment that is separate and isolated from other applications, operating systems, data, and internal networks. Sandboxes have several uses. In software development, a sandbox is used for testing new code, where it can be observed for unexpected compatibility issues, allowing software developers to troubleshoot the code without causing any harm to live systems and data.

In cybersecurity, a sandbox is used to open untrusted files, follow potentially malicious links, and analyze suspicious code and malware. If malware was installed and executed on a standard machine, the threat actor would be given remote access, malware may exfiltrate sensitive data, or in the case of ransomware, encrypt files. Since the sandbox is a secure environment, any malicious action has no consequences, and files can be studied in safety.

A sandbox is a virtual environment that is often configured to mimic a genuine endpoint. One of the first actions taken by malware is to explore the environment it is in to check whether it is on a genuine device. If not, it is likely not to run any malicious routines and may self-delete to prevent analysis. By configuring the sandbox to mirror a genuine endpoint, the malware can be tricked into performing its malicious routines, which are detected and logged. The intelligence gathered is fed into the email security solution, and all users of that solution, locally and globally, will be protected from that malware sample in the future.

Why is Message Sandboxing Necessary?

Traditional email security solutions check message headers, perform reputation checks of senders, scan email attachments with antivirus engines, follow embedded hyperlinks, and examine the content of the message for known spam and phishing signatures. For many years, these checks alone have been sufficient and ensure that more than 99% of spam and phishing emails are detected and blocked along with all known malware.

Email attacks have been getting much more sophisticated in recent years and new malware variants are being released at never-before-seen rates. A malware phishing campaign, for instance, will not just use one iteration of malware, but many, with each sample differing sufficiently to defeat signature-based detection mechanisms. Cybercriminals are using automation to spin up masses of samples and AI is being used to develop novel phishing methods.

AI and machine learning capabilities are now required in email security for blocking these zero-day threats, and email message sandboxing is necessary for detecting novel malware threats. Advanced email security solutions leverage AI, machine learning, and email sandboxing and protect against the rapidly evolving threat landscape. Without these features, many malicious messages will be delivered.

How to Set Up Message Sandboxing

The easiest way to get started and set up message sandboxing is to use SpamTitan Email Security. SpamTitan has been developed to be easy to set up and use by businesses of all sizes, from small offices and coffee shops to small and medium-sized businesses and large enterprises. Being cloud-based, there is no software to install, just a small configuration change to your MX record (information on how to do this is provided). The solution can be accessed through a web-based interface, and the solution can be configured in just a few minutes.

Users benefit from spam and phishing detection rates of more than 99.99%, a very low false positive rate and a Bitdefender-powered email sandbox. The email sandbox leverages advanced machine learning algorithms, aggressive behavior analysis, anti-evasion techniques, and memory snapshot comparison to detect zero-day threats.

Without an email sandbox, you are likely to be exposed to many malicious messages. With sandbox email protection, you have much better control of the content that reaches user inboxes.

U.S. Federal Agencies Offer Guidance on Combating Phishing

by Jennifer Marsh | Oct 25, 2023 | Phishing & Email Spam, Spam Advice |

Phishing is the most common way that malicious actors gain access to the networks of their victims. A single response to a phishing email by an employee is all it takes for a threat actor to get the foothold they need in the network to conduct a devastating attack. Once initial access has been gained, threat actors escalate privileges, move laterally, and conduct a range of malicious activities. What starts with a phishing email, often ends up with ransomware being deployed, with vast amounts of sensitive data stolen in between. This month, as part of Cybersecurity Awareness Week, the U.S. Cybersecurity and Infrastructure Security Agency (CISA), National Security Agency (NSA), Federal Bureau of Investigation (FBI), and the Multi-State Information Sharing and Analysis Center (MS-ISAC) issued joint guidance on combatting phishing.

Phishing is a term that covers social engineering techniques used by malicious actors to trick people into revealing sensitive information such as login credentials or installing malware. The federal agencies explained that it is all too common for IT security teams to put the blame on employees for clicking links in emails, opening malicious attachments, and disclosing their credentials, but this blame game doesn’t solve the problem. Organizations need to create, implement, and maintain phishing defenses that account for human error, as it is inevitable and impossible to avoid.

Various tactics, techniques, and procedures (TTPs) are used by cyber actors in these campaigns, and different mitigations are required for each type of attack. Credential phishing attacks are usually conducted via email, so one of the most important defenses in an email security solution. Email security solutions will reduce the volume of spam and phishing emails reaching inboxes. SpamTitan, for example, blocks more than 99.99% of spam and phishing emails. The federal agencies recommend using DMARC, Sender Policy Framework (SPF), and Domain Keys Identified Mail (DKIM) for verifying the sending server of received emails by checking published rules and DMARC, SPF, and DKIM, are all incorporated into SpamTitan.

An email security solution that relies on signature-based detection methods such as anti-virus engines will block all known malware but cannot block novel malware threats that have not yet been identified, and more novel malware variants are now being released than ever before. To improve defenses against malware-based phishing, email security solutions should incorporate machine-learning and AI-based detection, which look for the actions performed by emailed files rather than malware signatures. This is usually implemented through email sandboxing. Emails are sent to a safe and secure isolated environment where they are detonated, and their actions are analyzed for malicious actions.

No email security solution will block all malicious emails without also blocking an unacceptable number of genuine messages, and as the federal agencies point out, email security solutions cannot detect and block phishing attempts via SMS, instant messaging services, and voice phishing. It is therefore important to provide security awareness training to all members of the workforce. The purpose of security awareness training is to reduce susceptibility to phishing attempts by teaching employees about the threat of phishing, providing examples to help them recognize phishing attempts, and conditioning employees to stop and think and report any suspicious emails, SMS messages, and voice calls to their security teams.

Over time, employees will improve and get better at identifying phishing attempts, especially when training is combined with phishing simulations. Phishing simulations are a safe way to give employees practice at putting their training to the test, and these internal campaigns allow security teams to identify individuals who have not taken the training on board, as well as types of phishing emails that are proving effective, both of which can be addressed through further training. Security awareness training using SafeTitan has been shown to reduce susceptibility to phishing attempts by up to 80%; however, training will not totally eliminate employee mistakes. Employees are, after all, humans and not machines.

In addition to email security solutions and training, it is vital to add multi-factor authentication (MFA) to accounts. In the event that a phishing email bypasses technical defenses and fools an employee, MFA should prevent the obtained credentials from being used to access accounts. While any form of MFA is better than none, phishing-resistant MFA is recommended – FIDO or PKI-based MFA.

To increase protection against malware execution, denylists should be used to block malicious domains, URLs, and IP addresses, and rules should be implemented to prevent downloads of common executable files from the internet such as scr, .exe, .pif, .bat, .js, and .cpl files. This is easiest to implement with a web filtering solution such as WebTitan. WebTitan will also block all attempted visits to known malicious websites and can restrict access to only trusted, white-listed domains or URLs, or URLs and domains can be blocked by category.

Further information on improving phishing defenses can be found on the CISA website, and TitanHQ’s friendly sales team will be happy to discuss email security, web security, and security awareness training solutions with you and will help get you set up for a free trial of SpamTitan, WebTitan, and/or SafeTitan. The important thing is not to ignore the threat of phishing and to start taking steps to improve your defenses.

How to Sandbox Email Attachments

Do you know how to sandbox email attachments? If you have yet to start using a sandbox for email, you will be exposed to advanced malware and phishing threats. The good news is it is quick and easy to improve protection with a sandbox, and it requires no advanced techniques or skills, but before presenting an easy email sandboxing solution, we should explain why email sandboxing is now a vital part of email security

Email Sandboxing Detects Advanced and Sophisticated Threats

A hacker writes the code for a new malware variant or generates the code using an AI tool, and then sends that malware via email. A traditional email security solution will not block that malware, as it has not detected it before and it doesn’t have the malware signature in its definition list. The email would most likely be delivered, and the intended recipient could open it and infect their device with malware. From there, the entire network could be compromised and ransomware could be deployed.

How could a new, previously unseen threat be blocked? The answer is email sandboxing. When a file passes initial checks, such as AV scans, the attachment is sent to an email sandbox where its behavior is analyzed. It doesn’t matter if the malware has not been seen before. If the file performs any malicious actions, they will be detected, the threat will be blocked, and if that threat is encountered again, it will be immediately neutralized.

Email sandboxing is now an essential part of email security due to the sheer number of novel malware variants now being released. That includes brand new malware samples, malware with obfuscated code, polymorphic malware, and known malware samples that differ just enough to avoid signature-based detection mechanisms. Without behavioral analysis in a sandbox, these threats will be delivered.

TitanHQ’s Email Sandbox Service

by Jennifer Marsh | Oct 10, 2023 | Phishing & Email Spam, Spam Software |

Businesses are now targeted by advanced persistent threat actors looking for proprietary data, financially motivated threat actors looking to steal sensitive data and conduct extortion attacks, and hacktivist groups that aim to disrupt business operations.

Many of these attacks see initial access to internal networks and accounts gained via email. Credential phishing and malware phishing attempts serve a similar purpose and allow threat actors to obtain initial access to allow them to achieve their objectives, whether that is to gain persistent access for espionage purposes, to steal data, use ransomware, or wipe devices.

Email techniques such as phishing and spear phishing for credential theft or the use of malspam emails for delivering malware can be sophisticated and difficult for end users to detect. Further, advances in artificial intelligence have led to generative AI solutions that are capable of producing flawless phishing emails and generating novel social engineering techniques to trick users into taking the required actions – following a link, disclosing sensitive data, or downloading and executing malware.

Spam filters and secure email gateways have long protected businesses against these threats, but increasingly sophisticated techniques are now used that can bypass the protections of traditional email security solutions and reach end users. To combat these threats email security solutions have had to adapt. Cutting-edge email security solutions such as SpamTitan Email Security have AI and machine learning capabilities that are capable of detecting advanced and sophisticated attacks, in addition to DMARC, SPK, and DKIM reputation checks, and blacklists of known malicious IP addresses and domains.

One of the biggest threats comes from malware, either attached to emails or downloaded from URLs that are linked in email messages. For many years, antivirus engines have been effective at detecting and blocking malware threats, and while they still provide a degree of protection, AV engines are signature-based. When a new malware sample is detected, a unique signature is detected and added to a malware definition list. When a new file is received, it will be checked against all known signatures. If that signature is detected, the file will be quarantined or deleted.

New malware samples, which are being released at an incredible rate, will not be detected as malicious, as their signature has yet to be created and added to the list. These files will therefore not be detected as malicious and will be delivered to inboxes. To protect against this, advanced email security solutions use email sandboxing.

Email sandboxing involves creating an isolated, protected environment for analyzing suspicious emails. If front-end checks are passed, the email is sent to the sandbox for deep analysis. The sandbox is a protected environment where no harm can be caused, and files can be safely analyzed for malicious behavior.

TitanHQ’s Email Sandbox Service

In response to growing threats, TitanHQ added a next-generation email sandbox to its SpamTitan Email Security solution in 2019 to better protect users against malware, spear-phishing, advanced persistent threats (APTs), and to provide security teams with insights into new threats.

TitanHQ’s email sandbox service incorporates award-winning machine learning and behavioral analysis technologies, allowing security teams to safely detonate suspicious files in a secure environment that mirrors production endpoints. Malicious actors are tricked into thinking their malicious payloads have reached their intended target, and the malicious activities are detected. The sandbox analyzes documents, spreadsheets, application files, and executable files, and can detect malware, including polymorphic malware, and other sophisticated threats that have been developed for use in undetectable targeted attacks.

The TitanHQ email sandbox service leverages purpose-built, advanced machine learning algorithms, decoys and anti-evasion techniques, anti-exploit, and aggressive behavior analysis, and all results are checked against an extensive array of online repositories. The analysis takes from a few seconds to a few minutes, and if a malicious file is detected, the results will be uploaded to a cloud threat intelligence service and all users will be protected. If that threat is detected on any device globally, it will not need to be sent to the sandbox again and will be instantly neutralized.

How Does a Sandbox Work?

by Jennifer Marsh | Oct 5, 2023 | Phishing & Email Spam, Spam Software |

Sandboxing is a security feature that protects against malicious code. Rather than execute potentially unsafe code in a standard environment, it is sent to the sandbox – an isolated environment where no harm can be caused.

How Does a Sandbox Work?

A sandbox is an important cybersecurity tool for protecting host devices, operating systems, and data from being exposed to potential threats. The sandbox is a highly controlled system that is used to analyze untrusted applications, files, or code. The sandbox is isolated from the network and real data, and there are only essential resources that are authorized for use. It is not possible for a sandboxed file to access other parts of the network, resources, or the file system, only those specifically set up for the sandbox.

Sandboxes can have different environments. One of the most common implementations uses virtualization. A virtual machine (VM) is set up specifically to examine suspicious programs and code. Some sandboxes include emulation of operating systems to mimic a standard endpoint. Some malware samples perform checks of their environment before executing malicious routines to make sure they are not in a VM. If a VM is detected, the malware will not execute malicious routes and may self-delete to prevent analysis. By emulating a standard endpoint, these checks can be passed to allow analysis. Some sandboxes have full system emulation, which includes the host machine’s physical hardware as well as its operating system and software. These sandboxes provide deeper visibility into the behavior and impact of a program.

In email security, files, attachments, URLs, and programs are sent to the sandbox to check whether they are benign or malicious. The analyses can take between a few seconds to a few minutes, and if any malicious activity is detected, the file will be either quarantined and made available for further study or it will be deleted. Any other instances of that file will be removed from the email system, and any future encounters will see the file, attachment, URL, or program deleted.

SpamTitan Email Sandboxing

SpamTitan Email Security includes a Bitdefender-powered email sandbox to ensure users are protected against zero-day threats. All emails are subjected to a barrage of checks and tests, including scans using two different antivirus engines. SpamTitan features strong machine learning, static analysis, and behavior detection technologies to ensure that only files that require deep analysis get sent to the sandbox. This is important, as deeper analysis may take several minutes, so verified clean and safe messages will not be unduly delayed.

Files that are sent to the sandbox for deep analysis are executed and monitored for signs of malicious activity, with self-protection mechanisms in place to ensure every evasion attempt by a piece of malware is properly marked. The sandbox has purpose-built, advanced machine learning algorithms, decoys and anti-evasion techniques, anti-exploit, and aggressive behavior analysis. All results are checked across known threats in an extensive array of online repositories. If a malicious file is detected, the sandbox updates the Bitdefender’s cloud threat intelligence service – the Bitdefender Global Protective Network – and the sandbox will never have to analyze that threat again as it will be blocked globally.

If you want to improve protection against zero-day threats, give the TitanHQ team a call to find out more about SpamTitan. SpamTitan is available on a free trial to allow you to test it out in your own environment before making a purchase decision.

What is Sandbox Security?

by Jennifer Marsh | Oct 1, 2023 | Phishing & Email Spam, Spam Software |

What is sandbox security? In an IT sense, sandbox security refers to the use of an isolated environment for testing potentially malicious or unsafe code. The sandbox is an environment that resembles the organization’s real environment. The sandbox is made to look like it is a legitimate rather than a virtual environment; however, the sandbox is totally isolated from other systems and contains no real data.

A sandbox is used for malware analysis, testing potentially unsafe code, or as a guest environment with a tightly controlled set of resources, with no ability to inspect the host system or gain access to the networks, therefore not exposing any threats to real systems or data. For example, if a file needs to be opened and it is unclear whether it contains malicious code, it is opened in a sandbox. Security teams can assess the behavior of the file to determine if it is benign or malicious, and if it is the latter, no harm will be caused.

Sandboxes are commonly used for testing new code to determine whether it is safe and compatible with other systems, without actually putting those systems at risk. The sandbox is used to perform troubleshooting to identify any problematic parts of the code. One of the main benefits of sandbox security is blocking cyberattacks, and sandboxing has become indispensable for email security.

Email Sandboxing

Email sandboxing is the use of a sandbox environment for inbound email, which can be used to protect against phishing and malware threats. When an email is received that contains an attachment or a hyperlink, these can be evaluated in the sandbox before the message is released for delivery to the end user’s inbox. Phishing is one of the most common ways that malicious actors gain initial access to internal networks. Emails are often sent that contain hyperlinks to URLs that host phishing kits that steal credentials or sites hosting malware. These emails can be sent to a sandbox where the links can be followed, and the content of the URLs assessed. If a file download is triggered, the file can be analyzed to determine its behavior.

The same applies to email attachments. An email attachment such as a Word document or Excel spreadsheet may contain a malicious macro or other malicious code, which could provide a threat actor with remote access to the device and network. By opening the attachment in the sandbox, the behavior of the file can be analyzed safely. If found to be malicious, all other instances of that malware can be removed and if the file is received again, it will be automatically deleted. Security teams can also safely study malware to determine the nature of the threat and learn important information about the adversary and their intentions.

Why Is Email Sandboxing So Important?

Traditional email security solutions are effective at detecting and blocking known malware threats. They use one or more antivirus engines for scanning email attachments for known signatures of viruses and malware. If these signatures are detected, the threat will be blocked. The problem with signature-based detection is the signature must be known. While virus definition lists are updated on a daily or even hourly basis, new malware threats are constantly being released. If a new malware variant is received for which there is no signature, it will not be detected as malicious and will be delivered to an inbox where it can be executed.

Sandbox security plugs this security gap. If an attachment passes AV checks, it is sent to the sandbox for deep analysis of its behavior, allowing zero-day malware threats to be detected and blocked. Cybercriminals do not just use one version of a malware sample, they use many different versions, each differing sufficiently to evade AV checks. Without sandbox security, organizations are at risk of infection with these malware variants.

TitanHQ’s SpamTitan Email Security solution features dual antivirus engines for detecting known malware threats, and a Bitdefender-powered email sandbox for detecting zero day malware and phishing threats and provides security teams with valuable insights into new threats to help them mitigate risks. Give the TitanHQ team a call to find out more about how SpamTitan with sandbox security can improve your security posture. SpamTitan is also available on a free trial to allow you to put the product to the test and see for yourself the difference it makes.

Email Sandboxing is the Key to Blocking More Malware Threats

by Jennifer Marsh | Sep 27, 2023 | Phishing & Email Spam, Spam Software |

https://www.spamtitan.com/blog/email-sandboxing-key-blocking-malware-threats/Email security solutions with email sandboxing block more malware threats than traditional spam filters, even novel malware variants that have yet to be identified as malicious. Without this important feature, emails with malicious attachments will likely be delivered to inboxes where they can be opened by employees. All it takes is for one employee to open a malicious file for malware to be installed that gives a threat actor the foothold they need for a comprehensive attack on the network.

What is an Email Sandbox?

In cybersecurity terms, a sandbox is an isolated, virtual machine where potentially unsafe code can be executed in safety, files can be subjected to deep analysis, and URLs can be visited without risk. In the sandbox, the behavior of files, code, and URLs is inspected, and since the sandbox is not networked and there is no access to real data or applications, there is no risk of causing any damage. Email sandboxing is used to identify malicious code and URLs in emails. The email sandbox mirrors standard endpoints to trick malicious actors into thinking that they have reached their intended target. Emails may pass front-end tests that look at the reputation of the sender, email headers, the content of the messages, and subject attachments to signature-based anti-virus tests, but there is no guarantee that the emails are safe without sandbox-based behavioral analysis.

Why is Email Sandboxing Important?

Cyber threat actors have been developing techniques for bypassing standard email security solutions such as embedding malicious URLs in PDF attachments, hiding malicious content in compressed files, using multiple redirects on hyperlinks, and including links to legitimate cloud-based platforms such as SharePoint for distributing malware. Traditional email security solutions can filter out spam and phishing emails, but they often fail to block more sophisticated threats, especially zero-day malware threats. Email sandboxing provides an extra layer of protection against sophisticated threats such as spear-phishing emails, advanced persistent threats (APTs), and novel malware variants.

A few years ago, new malware variants were released at a fairly slow pace; however, threat actors are now using automation and artificial intelligence to generate new malware variants at an alarming rate. Malware samples are used that deviate sufficiently from a known threat to be able to bypass signature-based detection mechanisms, ensuring they reach their intended targets. Rather than just using one version of malware in their email campaigns, dozens of versions are created on a daily basis. While security awareness training will help employees identify and avoid suspicious emails, threat actors have become adept at social engineering and often hoodwink employees.

The SpamTitan Email Sandbox

The SpamTitan email sandbox is a powerful next-generation security feature with award-winning machine-learning and behavioral analysis technologies. Powered by Bitdefender, the SpamTitan sandbox for email allows files to be safely detonated where they can do no harm. Email attachments that pass the barrage of checks performed by SpamTitan are sent to the sandbox for deep analysis. The sandbox is a virtual environment that is configured to appear to be a typical endpoint and incorporates purpose-built, advanced machine learning algorithms, decoys and anti-evasion techniques, anti-exploit, and aggressive behavior analysis. Files are also subjected to checks across an extensive array of online repositories, with the sandbox checks taking just a few minutes. That ensures that genuine emails are not unduly delayed. If malicious properties are detected in the sandbox, the threat intelligence is passed to Bitdefender’s Global Protective Network (cloud threat intelligence service). If the threat is encountered again, it will be detected and blocked without having to be analyzed again in the sandbox.

The SpamTitan sandbox is used for a wide range of attachments, including office documents to check for malicious URLs, macros, and scripts, and all executable and application files. The sandbox allows SpamTitan to detect polymorphic malware and other threats that have been designed for use in undetectable targeted attacks. If a malicious file is detected, the email is not sent to a spam folder where it could be opened by an end user, it is quarantined in a directory on the local email server which only an administrator can access. Administrators may wish to conduct further investigations to gain insights into how their organization is being targeted.

Threat actors are conducting increasingly sophisticated attacks, so email security solutions need to be deployed that are capable of detecting these advanced threats. With zero-day threats on the rise, now is the ideal time to improve your email defenses with SpamTitan.

Commonly Asked Questions About Email Sandboxing

by Jennifer Marsh | Sep 15, 2023 | Phishing & Email Spam, Spam Software |

Commonly asked questions about email sandboxing so you know what to expect from an email security solution with a sandbox, and why this advanced feature is vital for email security.

What is an Email Sandbox?

One of the commonly asked questions about email sandboxing is what is an email sandbox? Like the children’s equivalent, it is a safe space for building, destroying, and experimenting. In cybersecurity terms, it is an isolated environment where harm cannot be caused to anything outside of that environment. An email sandbox is an isolated virtual machine that is used for performing risky actions, such as opening unknown attachments and analyzing files and URLs in depth, rather than using a real machine where there is a risk of harm being caused such as file encryption by ransomware, theft of sensitive information, or wiping of data.

Why is an Email Sandbox Important?

Email is the most common vector used in cyberattacks. Through emails, cyber threat actors can gain initial access to a protected network from where they can steal sensitive data or move laterally for a more comprehensive attack. One of the most common ways of gaining remote access is through malware. Once malware is downloaded, an attacker can remotely perform commands and gain full control of an infected device. While businesses use antivirus software to detect and remove malware, these solutions are signature-based. In order to detect malware, the signature of the malware must be in the definition list used by the anti-virus solution, which means the malware must have previously been encountered. Novel malware variants that have not yet been determined to be malicious will not be identified as such and will therefore be delivered to inboxes where they can be executed by employees. An email sandbox is used to safely detonate suspicious files and inspect their behaviors. The behavioral analysis allows previously unknown malware samples can be identified and blocked. This is important due to the volume of new malware samples that are now being released.

How Does an Email Sandbox Protect Against Malware?

Email security solutions with sandboxing perform the same front-end checks as traditional email security solutions and will identify and block many malicious messages. If the initial checks are passed, and the messages are determined to potentially pose a risk, they will be sent to the sandbox for behavioral analysis. Once inside the safety of the sandbox, the attachments will be opened and subjected to various tests. The sandbox is configured to appear to be a normal endpoint, so any malware will be tricked into running malicious commands as it would if it had reached its intended target. The actions of the file are assessed, and if they are determined to be malicious they will be sent to a quarantine folder. By performing these checks, new malware variants can be identified and blocked before any harm is caused.

Will Sandboxing Delay Message Delivery?

Performing standard checks of messages is a quick process, often causing imperceptible delays in mail delivery. Performing in-depth analysis takes longer, so there will be a delay in message delivery. Many emails will not need to be sent to the sandbox and will be delivered immediately, but if sandboxing is required, there will be a delay while the behaviors of the email and attachments are analyzed. Some malware has built-in anti-analysis capabilities and will delay any malicious processes to combat sandboxing. Time is therefore required to ensure full analysis. With SpamTitan, the delay will be no longer than 20 minutes.

How Can I Avoid Message Delivery Delays?

SpamTitan incorporates artificial intelligence and machine learning capabilities which minimize the number of emails that are sent to the sandbox, and SpamTitan will check every 15 seconds to ensure that emails are delivered as soon as the sandbox analysis is complete. SpamTitan’s sandbox is part of Bitdefender’s Global Protective Network, which ensures rapid checks of suspicious messages. To avoid delays, certain email addresses and domains can be added to a whitelist, which means they will not be sent to the sandbox for analysis, ensuring rapid delivery.

What are the Benefits of Email Sandboxing?

The sandbox provides an important extra layer of protection against malware threats and malicious links. It will detect advanced attacks early and prevent breaches, reduce incident response costs and efforts, reduce the threat-hunting burden, and increase the detection rate of elusive threats in the pre-execution stage, including APTs, targeted attacks, evasion techniques, obfuscated malware, custom malware, ransomware.

How Does the SpamTitan Sandbox Work?

SpamTitan will subject all inbound emails to a battery of front-end tests, and if these are passed but the email is still suspicious, the message and attachment will be sent to the sandbox and the user will be informed that the message is in the sandbox for review. The email and attachments will then be opened in an isolated cloud platform or a secure customer virtual environment. If malware is detected, the email is blocked and assigned ATP.Sandbox and will be listed under “Viruses” in the relevant quarantine report and the intelligence gathered will be used to protect all users from that threat in the future. After twenty minutes of interrogation, if no malicious actions are identified, the file is marked clean and the email is passed onto the recipient.

How Can I Find Out More About Email Security and Sandboxing?

If you have unacceptable numbers of spam and malicious messages being delivered to inboxes, are receiving large numbers of queries about suspicious emails from your employees, or if you have experienced a malware infection via email recently, you should speak with TitanHQ about improving email security with SpamTitan.

DarkGate Malware Infections Increase via Microsoft Teams Phishing and Malvertising Campaigns

by Jennifer Marsh | Sep 15, 2023 | Phishing & Email Spam |

Infections with DarkGate malware have been increasing in recent weeks. DarkGate malware was first identified in 2017 but was only used in limited attacks as the developer chose to use the malware privately against highly specific targets; however, over the summer the malware started being advertised on Russian-language cybercriminal forums and the developer has recruited a limited number of affiliates under the malware-as-a-service model. Reportedly, the developer offered the malware for sale to 10 people for an annual cost of $100,000.

DarkGate malware is written in Delphi and primarily serves as a malware loader, capable of downloading and executing other malware payloads. Typically, the malware payloads are executed in the memory which makes them hard to detect, since no files are written to the disk. The malware can also steal browser histories and Discord tokens and has a Windows Defender exclusion, reverse shell, hidden VNC, and keylogging capabilities.

The malware uses a variety of mechanisms to evade detection, including conducting checks for identifiers used by virtual machines, sandboxes, and anti-virus solutions and will alter its behavior based on the results of the checks, and has persistence mechanisms to ensure it is reloaded on reboot.

The advertising campaign appears to have been successful as distribution of the malware has increased significantly through spamming and phishing campaigns. One of those phishing campaigns uses compromised Office 365 accounts to send phishing messages that deliver DarkGate malware via Microsoft Teams messages.

Researchers at TrueSec identified messages that tricked recipients into clicking a link in the message that directs the or a SharePoint-hosted file called “Changes to the vacation schedule.zip” with the message advising employees that due to circumstances out of the company’s control, vacation time for certain employees has been canceled. The Zip file contains a malicious LNK file which masquerades as a PDF file with the same name as the zip file. Clicking the file will launch a VBScript file that will ultimately lead to the downloading and execution of DarkGate malware. Microsoft has security features to block attacks such as this – Safe Attachments and Safe Links – but neither of these features identified the file or link as malicious.

Other distribution campaigns have been detected in recent months, including a malvertising campaign that uses Google Ads to direct web users to a malicious site where the malware is hosted. The web page used in this campaign offered a legitimate network scanning tool, and while that tool was provided, extra files were bundled with the installation file that executed DarkGate malware.

Businesses are encouraged to defend against attacks through a defense-in-depth approach, involving multiple layers of protection such as an advanced AI-driven spam filtering solution, web filter, and endpoint protection software. Web filters will protect against malvertising campaigns, redirects to malicious websites, and malicious file downloads from the web. The increases in the use of SMS, Teams, and instant messaging services for distributing malicious links means these methods of link distribution should be incorporated into your security awareness training programs.

Email Sandboxing and Message Delivery Delays

by Jennifer Marsh | Sep 10, 2023 | Phishing & Email Spam, Spam Software |

Email sandboxing is important for security, as it will block threats that traditional email filters fail to detect. While sandboxing is now considered to be an essential element of email security, one disadvantage is that it will delay the delivery of emails. In this post, we will explain why that is and how email delivery delays can be minimized or avoided altogether.

What Does Queued for Sandbox Mean?

If you use SpamTitan or another email security solution with email sandboxing, you may see the message “email queued for sandbox” from time to time. The queued for sandbox meaning is the message has been determined to warrant further inspection and it has been sent to the sandbox for deeper analysis. This is most likely because the email includes an attachment that is determined to be risky, even though it has passed the initial antivirus scans.

While email sandboxing is important for security, there is a downside, and that is processing messages in a sandbox and conducting behavioral inspection takes a little time. That means there will be a delay in delivering messages that have been sandboxed while behavioral checks are performed. Messages will only be delivered once all sandbox checks have been passed. If a large volume of suspicious emails are received at the same time, messages will be queued for analysis, hence the queued for sandbox message being displayed.

Sandbox Delays for Inbound Emails

The processing of messages in a sandbox can take a little time. Cyber threat actors do not want their malware and malicious code analyzed in a sandbox, as it will allow their malware to be identified. Further, once a malware sample has been identified, details will be shared with all other users of that security solution, which means no user will have that malicious file delivered to their inbox. SpamTitan’s email sandbox is powered by Bitdefender, so all members of the Bitdefender network who subscribe to its feeds will also be protected.

Many malware samples now have anti-sandbox technologies to prevent this. When the malware is dropped on a device it will analyze the environment it is in before launching any malicious actions. If it senses it is in a sandbox it will terminate and may attempt to self-delete to prevent analysis. One technique often seen is delaying any malicious processes for a set time after the payload is delivered. Many sandboxes will only analyze files for a short period, and the delay may be sufficient to trick the sandbox into releasing the file. It is therefore necessary to give the sandbox sufficient time for a full analysis.

Are Your Sandbox Delays Too Long?

Conducting analyses of emails in a sandbox is resource-intensive and can take several minutes and there may be delays to email delivery that are too long for some businesses. There are ways to avoid this, which we will discuss next, but it may be due to the email security solution you are using. The SpamTitan email sandbox is part of Bitdefender’s Global Protective Network, which was chosen not only for cutting-edge threat detection but also the speed of analysis. If you are experiencing long delays receiving emails, you should take advantage of the free trial of SpamTitan to see the difference the solution makes to the speed of email delivery for emails that require sandbox analysis.

How the SpamTitan Sandbox for Email Minimizes Delays

SpamTitan does not send all messages to the sandbox to avoid unnecessary email delays. If a message is suspicious and the decision is taken to send it to the sandbox for analysis, SpamTitan will check to see if the analysis has been completed every 15 seconds to ensure it is released in the shortest possible time frame. Employees will be aware that they have received a message that has been sent to the sandbox as the message delivery status is displayed in their history. Provided all sandbox checks are passed, the email will be delivered. This process will take no longer than 20 minutes. If a file is determined to be legitimate, details are retained by SpamTitan so if the attachment or message is encountered again, it will not be subjected to further analysis in the sandbox.

How to Avoid Sandbox Delays to Message Delivery

There are ways to avoid messages being placed in the queue for sandbox inspection. While it is not always advisable for security reasons, it is possible to whitelist specific email addresses and domains. This will ensure that emails from important clients that need a rapid response will be delivered without delay and will not be sent to the sandbox. The problem with this approach is that if a whitelisted email address or a domain is compromised and used to send malicious messages, they will be delivered.

What Happens if a Message is Misclassified as Malicious?

False positives do occur with spam and phishing emails as email filtering is not an exact science. While this is rare with SpamTitan, any misclassified emails will not be deleted as they will be sent to a quarantine folder. That folder can be configured to be accessible only by an administrator. The administrator can then check the validity of the quarantined messages and release any false positives. Since SpamTitan has artificial intelligence and machine learning capabilities, it will learn from any false positives, thus reducing the false positive rate in the future.

How Does an Email Sandbox Block Malware?

by Jennifer Marsh | Sep 5, 2023 | Phishing & Email Spam, Spam Software |

You may have heard that email sandboxing is an important security feature, but how does an email sandbox block malware and why is this security feature necessary? In this post, we explain what an email sandbox is, why it is now an important element of email security, and how email sandboxes work.

An email sandbox is a secure and isolated environment where emails and their attachments are subjected to behavioral analysis. In the sandbox, malicious files and code can be safely detonated where no harm can be caused. Say an email is received that contains malicious code that is used to drop and execute ransomware on a device. Executing that code on a standard machine would initiate the process that ends with file encryption. Execute that code in an email sandbox and the malicious behavior would be detected and no harm would be caused. The email and code will then be eradicated from the email system, and the threat intelligence gathered will be sent to a global network to ensure that if the email or code is encountered again it will be immediately blocked.

Many Email Security Solutions Fail to Detect the Most Serious Threats

Traditional email security solutions perform many tests on emails to determine the likelihood of them being spam or malicious. DMARC and SPF are used to check the legitimacy of the sender, checks are performed on the reputation of an IP address/domain, and the subject, title, and body of a message are analyzed for signs of phishing and spam. Email attachments are also subject to anti-virus checks, which will identify and block all known malware variants. The result? Filtered emails contain no known spam, no known malicious hyperlinks, and no known malware.

The problem with traditional email security solutions is they are unable to detect unknown spam, phishing attempts, and malware. If a threat actor uses a previously unseen phishing email, which includes either a link to a fresh URL or a site with a good reputation, that email will most likely be delivered. If a new malware variant is sent via email, its signature will not be present in any virus or malware definition list and will similarly be delivered to an end user’s inbox. Threat intelligence is shared with email security solutions and they are constantly updated as new threats are found but there is a lag, during which time these threats will be delivered to inboxes. That is why an email sandbox is needed.

How an Email Sandbox Works

Antivirus scans will block the majority of malware, but not novel (zero-day) malware threats. When an email security solution has email sandboxing, the same checks are initially performed, and if they are passed, emails are sent to the sandbox for further analysis. The email sandbox is an isolated environment on a virtual machine that is configured to look like a genuine endpoint. As far as the threat actor is concerned, their email will have reached their intended target and the file should execute as it would on a standard machine.

In the sandbox, emails and attachments are opened and links are followed and behavior is analyzed in detail to determine if any malicious or suspicious actions occur such as a command-and-control center callbacks, attempted file encryption, or scans for running processes. If a Word document is opened that contains no hyperlinks, no macros, and no malicious scripts, and nothing suspicious occurs in the time it is present in the sandbox, the file will be determined as benign and the email will then be delivered to the intended recipient. If any malicious actions are detected, the file will be sent to a local quarantine directory where it can only be accessed by the administrator. The intelligence gathered will be sent to the global network and all users will be protected almost instantly. All copies of that message and the attachment will also be removed from the entire mail system.

Email Sandboxing and AI-Driven Threat Detection are Now Vital

Email sandboxing is now vital for email security as new malware variants are being released at an incredible rate and signature-based detection methods cannot detect new malware threats. In addition to email sandboxing, artificial intelligence must be leveraged to look for novel phishing messages, as phishing attempts are also increasing in sophistication. These AI-based checks look for messages that deviate from the typical messages received by a company, and greatly reduce the volume of spam and phishing emails that reach inboxes.

The threat landscape is constantly changing so advanced email defenses are now essential. If you are still using an email security solution without email sandboxing and AI-driven threat detection, your company is at risk.

Email Sandboxing, Pattern Filtering, and Other Much-Loved SpamTitan Features

by Jennifer Marsh | Sep 1, 2023 | Network Security, Spam Software |

SpamTitan is a next-generation anti-spam, anti-phishing, and anti-malware solution for businesses that incorporates AI-based threat detection, email sandboxing, and many other advanced email security features. Some of the most important and best-loved features of SpamTitan are explained below:

Email Sandboxing in SpamTitan

Email sandboxing is a vital element of email security, yet many email security solutions lack this feature. An email sandbox is a secure, virtual machine where links can be followed and attachments opened where they cannot cause any harm. A malicious link that leads to an automatic malware download can be followed in safety, and even the nastiest piece of malware can be executed without risk as the sandbox is isolated, not connected to any network, and contains no real data.

The sandbox is configured to appear to be a genuine endpoint in order to trick malicious actors into thinking malware has reached its intended target. When a file is opened in the sandbox it is subject to deep analysis, and any malicious or suspicious actions are detected. Emails are subject to a battery of front-end checks, including scans using two anti-virus engines, and any emails that pass these checks but are determined to potentially pose a risk are sent to the sandbox for behavioral analysis. That includes emails along with any attached documents, spreadsheets, and executable files.

Sandboxing for email is important because of the speed at which novel malware samples are used in attacks. Rather than just use one version of a keylogger in a campaign, a threat actor will use dozens of versions of that keylogger, each differing slightly to evade signature-based detection mechanisms. AI and automation are used by threat actors to churn out new malware variants rapidly, and signature-based detection alone is no longer good enough. With sandboxing, email protection is greatly improved against these zero-day threats which would otherwise be delivered to end users’ inboxes.

Pattern Filtering in SpamTitan

One of the most loved features of SpamTitan is Pattern Filtering. It saves IT security teams a considerable amount of their precious time by ensuring spammy and phishy emails are not delivered. The Pattern Filtering feature allows administrators to use their own terminology to block inbound emails. Simply set a word or phrase through Pattern Filtering, and SpamTitan will search the subject line and message body and can be configured to generate a warning or quarantine the email if the word or phrase is found.

An example of where this can be useful is combating the Nigerian scam/419 fraud, a type of advanced fee fraud. The 419 comes from Section 419 of the Nigerian Criminal Code which prohibits this kind of scam. While the scam is common with Nigerian cybercriminals, cybercriminal groups in many different countries also conduct this type of scam. While the themes of the emails vary, they all have the same aim. An example would be a prominent person who has substantial funds in their account has been unable to transfer the funds out of the country due to unfair restrictions. They offer to transfer these funds to the user’s account to get the money out of the country in exchange for a percentage of those funds as payment, which may be as high as 20%, which is a life-changing amount of money. The catch? In order to proceed, charges need to be covered and they must be paid in advance. The Pattern Filtering option can be used to block these emails by incorporating phrases commonly used in these emails.

Geo-Filtering in SpamTitan

SpamTitan also incorporates geo-filtering, which allows users to block emails from specific countries. If you never do business with countries in Africa, for example, you can simply block all emails coming from African IP addresses with a few clicks of a mouse, rather than manually blocking IP addresses from which you get a lot of spam emails. This feature saves IT teams a considerable amount of time. One user who has benefited greatly from this feature is Benjamin Jeffrey, IT manager at M&M Golf Cars. His company was receiving many requests from countries that the company does not do business with and was getting flooded with spam emails from a specific IP subnet in a country. He configured the geo-filtering and instantly blocked all those messages. When he checked 6 months after configuring that feature, around 12,000 emails had been blocked. Geo-blocking is also useful for blocking malware quickly. Malware distribution campaigns are often launched from a handful of countries, and geo-filtering can be used to block those messages with ease.

AI and Machine Learning in SpamTitan

SpamTitan has AI and machine learning capabilities to improve the detection of spam and phishing emails. These technologies learn about the emails that are typically received by a company and create a baseline against which new emails can be measured. When emails deviate from the norms, they are flagged as risky and are subjected to more stringent security checks or are quarantined for manual inspection. These technologies greatly improve spam and phishing email catch rates and allow SpamTitan to improve day-by-day. These technologies are a vital defense against zero-day phishing threats – new threats that have not been encountered on the 500+ million endpoints from which threat intelligence is gathered.
