New Version of Zeus Malware Evades Detection

Bank-credential-stealing malware Zeus receives an upgrade from hackers, making it undetectable by malware scanners.

A new version of the infamous Zeus malware has been discovered by experts at Malcovery Security. The malware was found attached as a .zip file to spam emails which took on the appearance of legitimate organizations such as ADP, Better Business Bureau, and the British tax authority HMRC.

When downloaded and unpacked, a small application called UPATRE downloads a .enc file used to decrypt a file called GameOver Zeus. Because this files has an extension of .enc and not .exe, malware scanners are having a difficult time flagging it as malicious because technically, it isn’t malware.

Security experts advise administrators to look over their logs for the .enc file extension on any downloaded files.
