Description: 

This worm spreads by dropping copies of itself in available network shares. It also takes advantage of the Windows vulnerability whose description is found in the following Microsoft Web page:

It also drops a file detected by Trend Micro as TROJ_ROOTKIT.E in the Windows system folder.

It generates IP addresses and spreads by attempting to drop a copy of itself in target addresses' default shares. If the said shares are password-protected, it uses a hardcoded list of user names and passwords as its login credentials to gain access.

Using a random port, it connects to an Internet Relay Chat (IRC) server and joins a specific channel, where it listens for commands from a remote malicious user. The said commands are executed locally on affected machines.

Moreover, this worm performs denial of service (DoS) attacks against target sites using different flood methods.
