Warning over Obama sex scandal spam

The spam campaign alleges to link to a video of Barack Obama

Web monitoring firms are warning IT administrators to update their spam filters after a massive new spamming campaign was detected.

Inboxes are filling up with spam claiming to have a link to a web site that carries video footage of a sexual indiscretion committed by presidential candidate Barack Obama.

It alleges to show footage of him having sex with Ukrainians after a visit to the country last year.

"Users who click the link are shown a pornographic video," said Websense. "While the video plays for 14 seconds, malicious applications are installed on the victim's machine."

The malware consists of a Trojan that allows remote control of the user's machine using an application called 809.exe in the user's Temporary Internet Files folder.

It also installs a Browser Helper Object which steals keystrokes and forwards them to a server controlled by the malware distributors.
