MySpace.com pages are being infected with a link to a computer virus, and another may be targeting Skype’s text chat for the first time, security firm F-Secure announced on Tuesday.

User pages at the well-known social networking site MySpace are being modified by versions of the Zlob Trojan, which is installing code that overlays its own window on top of the page, F-Secure Corp.’s chief researcher Mikko Hypponen wrote in the company’s security blog.

The F-Secure blog states: “Some older Warezov variants have used other Instant Messaging client in a similar fashion, but not Skype.”

The messages looked like this:

The blog further adds: “We detect the binary at that download location as Warezov.ly.”

There’s something new spreading on MySpace.

It ends up modifying existing profiles, overlaying the content with a message which reads:

“If you follow the link, you’ll end up with a download. This is a Zlob variant.”

F-Secure has not yet completed their analysis on this, however it seems that when run it tries to modify the MySpace page to include a code snippet that is responsible for the malicious download link.

Skype users had alerted F-Secure that they had received links to files infected with a worm called Warezov.

“Some older Warezov variants have used other instant messaging [clients] in a similar fashion, but not Skype,” Hypponen wrote.

Warezov gathers e-mail addresses it finds on infected computers and sends itself as an attachment to those recipients. It also tries to download newer versions of itself from the internet.
