Banking Trojans have long posed a threat to businesses, but one in particular has stood head and shoulders above the rest in 2020: The Emotet Trojan.
Emotet: The Biggest Malware Threat in 2020
The Emotet Trojan first appeared in 2014 and was initially a banking Trojan, which was used to steal sensitive data such as bank account information from browsers when the user logs into their bank account. The Emotet Trojan has since been developed and it has now evolved into a much bigger threat.
Emotet is now far more effective at spreading to other devices, using a worm like element to infect other devices on the network as well as hijacking the user’s email account and using it to send copies of itself to victims’ contacts. Infected devices are added to the Emotet botnet, and have been used in attacks on other organizations. The operators of Emotet have now joined forces with other cybercriminal operations and are using their malware to deliver other Trojans such as TrickBot and QakBot, which in turn are used to deliver ransomware.
Data from HP Inc. revealed Emotet infections increased by 1,200% from Q2 to Q3, showing the extent to which activity has increased recently. Data from Check point show Emotet is the biggest malware threat, accounting for 12% of all infections in October 2020. TrickBot, which is delivered by Emotet, is the second biggest threat, accounting for 4% of infections.
Emotet and TrickBot are Driving the Increase in Ransomware Infections
The Emotet and TrickBot Trojans are driving the increase in ransomware infections globally, especially attacks on healthcare organizations. The healthcare industry in the United States is being targeted by ransomware gangs due to the increased chance of the ransom being paid. In many cases, the recent ransomware attacks have been made possible due to previous Emotet an TrickBot infections.
Unfortunately, due to the efficient way that Emotet spreads, removing the malware can be problematic. It is probable that more than one device has been infected, and when the Trojan is removed from one device, it is often reinfected by other infected devices on the network.
Emotet is primarily spread via phishing emails, most commonly using malicious macros in Word documents and Excel spreadsheets, although JavaScript attachments are also known to be used. The lures used in the phishing emails are highly varied, often using topical lures linked to recent news events, COVID-19, and holiday season lures in the run up to Halloween, Black Friday, and Cyber Monday.
The best way of preventing attacks is stopping the Emotet emails from reaching inboxes and making sure that employees are trained how to recognize phishing emails.
How SpamTitan Can Protect Your Organization
SpamTitan use a wide range of different techniques to identify phishing emails that are used to deliver malware such as Emotet. These measures provide layered protection, so should one check fail to identify the threat, several others are in place to provide protection.
SpamTitan uses dual antivirus engines to identify previously seen malware variants and email sandboxing to identify new (zero day) malware threats. Suspicious email attachments are sent to the sandbox where they are subjected to in depth analysis to identify malicious actions such as command and control center callbacks.
Users can set controls to quarantine or reject messages with certain types of email attachments, and while blocking Word and Excel documents and spreadsheets is not practical for most businesses, setting rules to quarantine these files for manual review if they have macros is certainly wise, as is blocking JavaScript files and other file types commonly used to install malware.
SpamTitan uses Sender Policy Framework (SPF) and DMARC to block spoofing and email impersonation attacks, which are used to convince employees to open attachments and click malicious links. SpamTitan also includes outbound scanning, which detects devices that have potentially been infected and prevents messages from spreading Emotet internally and to business contacts.
There are many cybersecurity solutions that can provide protection against malware, but finding one that is easy to use, effective, and reasonably priced can be a challenge.
SpamTitan ticks all of those boxes. It is the most and best ranked email security solution on Capterra, GetApp and Software Advice, has achieved a rating of 4.9 out of 5 on Google reviews, and is listed in the top three in the email security gateway, MSP email security, and email security for Office 365 categories.
