More Information

W32/Forbot-R is a worm and backdoor for the Windows platform.

W32/Forbot-R spreads to network shares and by exploiting backdoors opened by other malware.

When run W32/Forbot-R copies itself to the Windows system folder as syscfg32.exe. The worm adds the following registry entries to ensure that the copy is run each time Windows is started.

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Win32 USB2 Driver = "syscfg32.exe"

HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce
Win32 USB2 Driver = "syscfg32.exe"

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Win32 USB2 Driver = "syscfg32.exe"

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Win32 USB2 Driver = "syscfg32.exe"

HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce
Win32 USB2 Driver = "syscfg32.exe"

The backdoor component of W32/Forbot-R may be used to launch distributed denial of service attacks, run a Socks proxy server or obtain information about the infected computer.

W32/Forbot-R attempts to disable other worms, such as members of the W32/Bagle family.
