Researchers at web security firm Websense have discovered a new Koobface campaign that is spreading on Facebook via direct messages sent from compromised accounts. Those behind the latest campaign have attempted to obfuscate the URL in each message to avoid detection by security software or Facebook security controls, researchers said Friday. Recipients of the message are told to follow a link to view a video in which they appear. After clicking the link, users are directed to a malicious site, where they are instructed to download a "missing Flash plug-in" to play the supposed video. The download is actually a variant of the Koobface worm. - AM
A new wave of malicious emails containing a fake Microsoft Windows security update began hitting inboxes in an effort to spread malware, researchers at anti-virus firm Sophos have warned. The messages, which appear to be sent from Microsoft's security team and contain the subject line "Update your Windows," advise users to update their operating system by downloading an attached executable file, Graham Cluley, senior technology consultant at Sophos, wrote in a blog post Tuesday. The attached file, called "KB453396-ENU.zip," is actually an AutoRun worm. Users should be advised that Microsoft never distributes security updates via email attachments, Cluley said. - AM
Researchers at the nonprofit Shadowserver Foundation believe they have identified a new version of either the Storm or Waledac worm, thanks to a large-scale influx of New Year's-themed spam. The emails purport to be a New Year's greeting card but contain a link to a malicious domain, claiming to host a fake Flash Player that actually is an exploit. The evil domains use fast-flux techniques to hide the host server. "The whole point of this botnet is to install malware onto systems of unsuspected visitors," researcher Steven Adair wrote on the Shadowserver blog. Storm first appeared on the scene in 2007, capitalizing on current events and holidays, and was effectively replaced by Waledac in 2009. - DK

Researchers at ESET are tracking yet another outbreak of the insidious Koobface worm. The malware is spreading through Facebook messages that claim to offer hidden cameras showing erotic video. Users are asked to click on a link, which leads to a request to download a fake Adobe Flash update. If infected, machines are hit with a potent trojan cocktail that can block access to security websites, change DNS settings, install rogue anti-virus software and steal passwords. One unique feature of the ruse is that users can only click on the malicious link once — the next time they reach an error page. "It's assuming you're a security researcher trying to do research on it," Randy Abrams, director of technical education at ESET, told SCMagazineUS.com on Wednesday. — DK
