New IM Worm Talks In Tongues
Although the Kelvir.hi worm is not an extremely high-level risk -- Symantec, for example, lists it as a "2" in its 1 through 5 ranking -- it takes a unique tack to language, for it speaks in tongues.
Ten to be exact.
Kelvir.hi, which spreads via Microsoft's MSN IM network, checks for the system's default language, then periodically blasts out messages in that language to contacts hijacked from the victim's machine. If Dutch is the default language, for instance, the message reads "lol ik heb je foto gevonden;" if English, "haha i found your picture!"
The message may also contain a link to the worm; if the recipient clicks on the link, his machine's infected.
Kelvir.hi also drops a copy of Spybot onto the PC; this spyware-style bot hides in the background and listens for commands transmitted by the attacker. Those commands can tell the bot to scan for specific files, download or upload files, steal passwords, or even log all keystrokes.
Other languages detected and used by Kelvir.hi include French, German, Greek, Italian, Portuguese, Swedish, Spanish, and Turkish.
Most anti-virus vendors have already updated their definition files to detect and delete Kelvir.hi.
