Brief Description 

    

Sdbot.EXG is a worm that connects to several IRC servers in order to receive remote control commands, acting as a backdoor. It can be instructed to download and run files, launch DoS (Denial of Service) attacks, add or remove shared resources, search for vulnerable computers, etc.

Additionally, Sdbot.EXG installs its own FTP (File Transfer Protocol) and TFTP (Trivial File Transfer Protocol) servers on the affected computer in order to spread to other systems.

Sdbot.EXG exploits the vulnerabilities LSASS, RPC DCOM, Workstation Service, Plug and Play and SQL Server Resolution Service to spread across the Internet.

 

It is highly recommendable to download the security patches for the vulnerabilities LSASS, RPC DCOM, Workstation Service, Plug and Play and SQL Server Resolution Service from the Microsoft website.

Visible Symptoms 

    

Sdbot.EXG is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.
