Aggressive Malware Threats In Circulation

Some bad malware hombres are out there, and we’ve got the scoop on each of them right here for you.

  • Herbalife or “copier” file Locky variant ransomware

Summary – As of 9/19, Barracuda Advanced Technology Group is monitoring an aggressive new ransomware threat.  It will come as an email from a false source with a subject of “Herbalife” or include a reference to a “copier” file delivery. Victims who pay the ransom will reportedly not receive a decryptor to break the hack. See Barracuda’s blog for examples of how these emails might look.  Barracuda researchers have confirmed that this attack is using a Locky variant with a single identifier.  The identifier allows the attacker to identify the victim so that when the victim pays the ransom, the attacker can send that victim the decryptor.  In this attack, all victims get the same identifier, which means that victims who pay the ransom will not get a decryptor because it will be impossible for the criminal to identify them.

How to protect against this threat:  Be aware of the red flags associated with this particular malware and avoid opening any emails with either of these references. Also, always be sure you’re using solid email cyber security best practices, including:

Assessing the basic ‘legitimacy’ of an email (Any weird grammar usage or misspellings throughout the email, or with the company name itself? Do any included links or graphics used within the email actually point to a seemingly unassociated website?)
Not clicking on links within the email (copy and paste any provided links into a new browser window instead)
Not downloading any files
