UPS trojan strikes again

A trojan masquerading as an email notice from UPS, the delivery service, tries to dupe users into clicking on an enclosure to download malware. The trick is not new, but seems to be reemerging.

“It's not a new technique for fooling people into opening a malicious attachment, but clearly the hackers still think it has some legs,” wrote Graham Cluley, senior technology consultant at Sophos, in a post on his blog.

The message claims that a package could not be delivered – that is, UPS did not deliver a package because an incorrect destination address was specified.

The trojan is named TrojanSpy.ZBot.DGI (VirusBuster), Trojan-Dropper.Delf (Ikarus) or VirTool:Win32/DelfInject.gen!J (Microsoft), according to email security firm MX Lab.
The “From” address is spoofed and contains “United Postal Service tracking[at]ups[dot]com.”

“The trojan hides itself inside the file Invoice_8612112.exe once you have extracted the ZIP archive Names and numbers may vary,” said an advisory on the MX Lab blog.
