MSN Messenger worm turn PCs into zombies
by Nikola Strahija on February 5th, 2005 A worm spreading via MSN Messenger is turning infected Windows PCs into zombie drones. The Bropia-F worm spreads by offering "sexy image files" to IM contacts of infected users.
Instead of sexy pictures, users who accept and open infected files get a comical photo of a roasted chicken with a bikini tan line. In the background, Bropia-F installs a variant of the Agobot (aka Pahtbot or Rbot) worm, opening a backdoor on infected systems. The bot can then be used to collect system information, log keystrokes and relay spam.
Bropia-F arrives in a file about 184 KB in size. It tries to spread to other MSN Messenger users by sending a copy of itself under one of these filenames: bedroom-thongs.pif, hot.pif, lmao.pif, lol.scr, naked_drunk.pif, new_webcam.pif, rofl.pif, underware. pif and webcam.pif.
Sightings of the worm have been reported in Taiwan, China, Korea, Costa Rica and the US since it began spreading earlier this week. Anti-virus firms rate the worm as a medium risk.
Users are also advised to apply the principles of safe computing and to exercise caution in the programs they allow to self-install on their PCs. Windows users are also advised to update their antivirus signature files to detect the worm, just in case.
