Information on the “Happy New Year” malware

Experts at SophosLabs have reminded computer users of the threat posed by unsolicited email following a large scale worm outbreak over the new year holiday period. The W32/Dref-V email worm, first seen on 30 December, hit email systems hard in the last two days of 2006 posing as an electronic greeting celebrating the new year.

With subject lines such as “Happy New Year!”, “Fun Filled New Year!” and “Happy 2007!” the worm spread via email with a malicious executable attachment (called names such as postcard.exe and Greeting Card.exe). This is the Sophos virus database listing for the W32/Dref-V worm:
