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

The latest scam to hit Facebook is trying to trick users into spreading spam with the offer of a "dislike" button, Graham Cluley, senior technology consultant at anti-virus firm Sophos, said in a blog post Monday. Many users have been clamoring for such a capability, as they could use the button to give a thumbs-down to other posts, links or uploads of which they are not fond. A "like" button already exists. The scam entices users to click on a link and install a rogue Facebook application, Cluley said. If the app is given permission to run, it posts spam messages from the user's account and prompts them to complete an online survey that makes money for the perpetrators. — AM

Researchers at anti-spam firm Red Condor are warning users of malicious emails crafted to look like a legitimate thread of forwarded messages discussing Adobe software vulnerabilities. The thread begins with an email supposedly coming from an employee in Adobe's Risk Management department that warns recipients of a denial-of service-vulnerability and urges them to apply a patch. Adding legitimacy to the campaign, the emails appear to have been forwarded by people of higher positions in the recipient's organization. The messages contain a link to an executable, which has been identified as a trojan. Adobe, in a Wednesday blog post, advised people to ignore the email. — AM

Researchers identified the malware, an ".exe" file instead of a legitimate ".crx" extension, as a trojan that attempts to block access to Google and Yahoo pages and redirect users to fake versions of those sites. — AM

The bogus messages, which have been spoofed to make it look like they are coming from Facebook, falsely inform recipients that their password has been changed due to safety concerns. They are encouraged to click on a ZIP attachment to view their new password. However, that file actually contains a poorly detected executable that installs additional malware on the victim's computer and joins it as part of the Bredolab botnet. -- DK
