Another MSN worm spreading with the same tactics as usual, “Wanna see my pictures before i send em to facebook?” and so on.
The only really interesting thing about this worm is it sends the message in the language of the locale installed on the infected machine, this is pretty intelligent and is much more likely to work as most of the people on sometimes contact list are probably from the same country or at least use the same language.
The IRCBOT-RB Trojan poses as messages containing links to pictures on social networking sites such as MySpace and Facebook. Typical come-ons involve messages such as “Wanna see my pictures before i send em to facebook?”. Clicking on a link takes users to booby-trapped websites.
Unusually, the polyglot malware changes these messages according to the language of the affected operating system used. Compromised machines are infected by a simple bot agent that leaves the hardware hooked up to a central control server, awaiting instructions.
This would mean it’s much more believable than someone who speaks Portuguese to their friends sending a message in English. As usual please educate people not to blindly follow or click links and definitely don’t accept files sent by friends on MSN/Yahoo! or AIM as they are most likely auto-generated by a trojan.
Do message the person back manually and ask them if they really sent it.
