This worm has backdoor capabilities, which enable it to connect to the Internet Relay Chat (IRC) server, fbi.thuggaming.net/MyNiggazPwn.net. Once a connection is established, it joins the IRC channel ##Hellbot3##, where it listens for certain commands from a remote malicious user. It executes these commands locally on an affected system, providing the remote user virtual control over the affected system.
Moreover, it prevents users from accessing several antivirus and security Web sites by redirecting the connection to the local machine.
