Delivery package 170SophosLabs has seen a widely spammed-out malware campaign today, designed to trick unsuspecting computer users into infecting their computers with a Trojan horse.

The messages use a variety of subject lines, and appear to contain adaptions depending on whether the criminals believe they are targeting a British or American computer user (Brits are lured into opening the attachment with an email seemingly from the Royal Mail, whereas American-based recipients may believe the message is from USPS).

Package list

The wording can vary, but here are some examples of both the USPS and Royal Mail versions of the malicious email:

Package usps

Package royal mail

Contained inside the ZIP file is a Trojan horse, detected by Sophos products proactively as Mal/Bredo-Q.

The malware is only capable of infecting computers running Windows.
