The malware we’re talking about is a new version of the FacexWorm. This malware is nothing new. It was first spotted roaming Messenger in August 2017, infecting computers with adware.Here’s how it works. It is spread with malicious messages sent through Messenger. The message appears to have been sent by someone in the victim’s contact list.

The malicious messages typically contain a link that takes the victim to a fake YouTube site. If a victim is using Google Chrome, the scammers will try and trick the victim into downloading a malicious Chrome extension.Note: The extension is currently named “Koblo.” However, the criminals behind the scam could change the extension name at any time in the future as well. 

Old worm, new tricks

FacexWorm’s new trick is, instead of just simply adware, the worm has gained more dangerous abilities.For one, it can now steal the credentials and passwords of its victims across multiple websites. It can also hijack traffic from trading platforms and steal cryptocurrency funds. And lastly, it can cryptojack your computer by injecting malicious cryptomining code on a webpage.From there, it can spread even further by sending more malicious messages to a victim’s Messenger contacts.
