Beware of Emotet

News Desk

Emotet, a malicious Trojan, is dwarfing the impact and financial losses of previous Trojans, is currently cutting a path of destruction across the world.

This is according to Linda Morris of Smart Technology Centre (STC), a leading internet service provider (ISP) and IT technology partner, who says it was initially intended as a banking Trojan.  “Emotet is constantly evolving to gain access to unsuspecting victims’ computer systems,” she adds.

Often disguised as a financial-related file, it is spread through spam e-mails and will arrive in your inbox containing familiar branding and malicious script, a malicious link or a macro-enabled document file that could look like a word or an excel document.

If you click on the attachment or the link, the code downloads and installs the malware on the host system, from where it contacts its port of call to deliver the payload that it was intended for.

What makes Emotet scary, is that it could launch a host of attacks ranging from ransomware and banking Trojans, through to stealing banking and sensitive information; in addition to raiding your contact list.  It perpetuates the vicious cycle by sending your contacts infected e-mails from your e-mail address, adding a guise of legitimacy to unsuspecting victims.

Emotet employs polymorphic evasion tactics to fly under the radar of anti-malware products.  It literally changes itself every time it is downloaded, which makes it hard for signature-based cyber security systems to detect it.  Its worm-like capabilities also means that it can spread through a network of connected computers.

“In our hyper connected world where we are dependent on technology for virtually every aspect of our business and lifestyle transacting, no business is safe unless security and protocols are a top priority.  In terms of the human element, do not open any strange links or attachments, especially if you are not expecting it, no matter how legitimate the e-mail may appear to be.  If you feel uneasy, pick up a phone and check with the person whether they sent anything to you.

“Make sure that security protection is deployed and up to date and that your IT partner runs regular checks.  Smart Technology Centre recommends the Sophos product set, one of the best in class internet security solutions according to Gartner, which incorporates artificial intelligence to proactively block malicious viruses, malware, exploits and ransomware attacks,” concludes Linda.
