Mytob.BD is a worm with backdoor characteristics that connects to an IRC server in order to receive remote control commands, such as delete, download and run files.
It downloads other malware to the affected computer, such as the worm detected as Faribot.A.
Aditionally, it prevents users from accessing certain web pages, belonging to antivirus companies.
Mytob.BD uses different means to spread:
- It spreads via e-mail, in a message with variable characteristics.
- It exploits the LSASS vulnerability to spread across the Internet.
- It attempts to access network shared resources using passwords that are typical or easy to guess.
If you have a Windows XP/2000 computer, it is highly recommendable to download the security patch for the LSASS vulnerability from the Microsoft website.
Mytob.BD is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.
