After stormy start, worm turns to love in major new attack

January 24, 2007 Sophos Press Release


Some of the subject lines used in the latest malicious email attack

Experts at SophosLabs™, Sophos's global network of virus, spyware and spam analysis centers, have warned of a major new malicious attack occuring against internet users since 14:00 GMT. New variants of the Dorf malware family (earlier incarnations of which purported to be breaking news of deaths caused by European storms) are now using disguises associated with love and greeting cards.

Subject lines used in the spam campaign are many and varied. Some of them include "You're so Far Away", "I Dream of you", "Old Together", "Dream Date Coupon", "Together You and I", "A Bouquet of Love", "So in Love", "Cuddle Up", and "Vacation Love".

Attached to the emails are files called flash postcard.exe or greetingcard.exe, which contain the worm.

Opening the attached files on a PC activates the worm, which then sends itself to other email addresses found on the now infected computer. Sophos analysts believe that the worm code is designed to attempt to download further malicious code from the internet designed to take over the PC, convert it into part of a zombie network, and use it to send spam on behalf of hacking gangs.

Sophos's anti-spam products are intercepting the emails to prevent them from reaching users' inboxes, and anti-virus experts have analyzed and defended customers against the worm using Behavioral Genotype® Protection (which names the malware as Mal/HckPk-A).

"This attack is taking place against internet users right now around the world. Hackers are trying to break into innocent users' PCs to turn them into a proxy for the relaying of spam," said Graham Cluley, senior technology consultant. "People must learn to think before they click. It may be tempting to open an attachment which you think is a greeting card or a message from a loved one, but love can get you into trouble sometimes. The best defense is common sense, combined with up-to-date anti-virus software and email filtering at your gateway."

This week Sophos published its annual Security Threat Report, which detailed the increased use by hackers of targeted Trojan horses in their attempts to infect computer users for the purposes of sending spam.

Sophos recommends companies automatically update their corporate virus protection, and run a consolidated solution at the email gateway to defend against malware, spyware and spam.
