New IM Worm On The Loose

elfarto writes "Techweb is reporting that a new worm that spreads via Microsoft's instant messaging client began badgering users Monday, several security firms said. Dubbed Funner, the worm propagates by sending itself to all the contacts listed in the user's copy of MSN Messenger, Microsoft's IM client. There is an analysis on Symantec Security Response Site; apparently the worm tries to download stuff from www.78p.com and adds entries to the hosts file pointing to more that 400 Chinese porn sites. The worm also sends itself to the whole contact list as funny.exe so it requires the user interaction to actually execute it. "
