Trend Micro Virus Alert: WORM_CHOD.D

WORM_CHOD.D is a non-destructive, memory-resident worm that propagates via email and MSN Messenger. It spreads via email by sending copies of itself as an attachment to email messages,by gathering addresses from the Windows registry of affected machines. It spreads via MSN Messenger by sending a URL to all available contacts in the messaging application. Once the users click the URL, they are immediately redirected to a Web site, where this worm automatically downloads itself. This worm is currently spreading in-the-wild and infecting computers running Windows ME, NT, 2000, XP and Server 2003.

Upon execution, it creates a randomly generated folder in the Windows system folder and drops files in this created folder. It also modifies a particular registry entry to disable the services used by Trend Micro products.

The worm's backdoor capabilities attempt to open port 37737 to connect to a certain Internet Relay Chat (IRC) server. If it fails to open the port, it attempts to open random TCP ports. It then joins a particular IRC channel, where it waits for malicious commands from a remote malicious user. It also tries to use a password recovery tool to retrieve passwords available on an affected system. It can send the obtained information to the malicious user using its backdoor capabilities.
