Emotet gang takes their operation to a whole new level, showing why they’re today’s most dangerous malware. It would seem it now has taken on new tactics in the form of hijacking users old email chains and then responding from a spoofed address to portray legitimacy, this additional tactic can heighten a hackers chances when stealing financial information once a victim has been lured into clicking on said malicious content. Targeted emails appears to affect both private and public sectors, including government, particularly those that provide financial and banking services.
Emotet is a known banking Trojan, discovered five years ago, first in Europe and the USA. It started out stealing information from individuals, like credit card details. It has been lurking around since 2014 and has evolved tremendously over the years, becoming major threat that infiltrates corporate networks and spreads other strains of malware.
It injects itself into a user’s device via malspam links or attachments, with the intent to steal financial data. It targets banking emails and can sometimes deploy further attacks once inside a device.
The Emotet malware gang is now using a tactic that has been previously seen used by nation-state hackers.
The U.S. Department of Homeland Security published an alert on Emotet in July 2018, describing it as “an advanced, modular banking Trojan that primarily functions as a downloader or dropper of other banking Trojans,” and warning that it’s very difficult to combat, capable of evading typical signature-based detection, and determined to spread itself. The alert explains that “Emotet infections have cost SLTT (state, local, tribal, and territorial) governments up to $1 million per incident to remediate.”
This campaign targeted mainly Chile and used living off the land techniques (LotL) to bypass Virus Total detections. This up and coming tactic uses already installed tools on a users’ device to remain undetected for as long as possible.
