W32/Forbot-BB is a worm and backdoor for the Windows platform. The worm spreads using network shares.

The backdoor component listens for instructions from a remote attacker.

W32/Forbot-BB copies itself to the Windows system folder as aim.exe and adds the following registry entries:

Aim Quick Start = "Aim.exe"

Aim Quick Start = "Aim.exe"

Aim Quick Start = "Aim.exe"

Aim Quick Start = "Aim.exe"

Aim Quick Start = "Aim.exe"

The worm also installs itself as a service named "Aim Quick Start".

The backdoor allows a remote attacker to control the infected computer, providing functions such as:

File transfer
Service control
