More Information
W32/Forbot-BK is a network worm with backdoor Trojan functionality.
W32/Forbot-BK spreads through network shares and by exploiting the LSASS (MS04-011) software vulnerability. The Trojan may also spread through backdoors left open by other malware.
When first run W32/Forbot-BK copies itself to the Windows system folder as MVSECN.EXE. In order to run automatically each time Windows is started, W32/Forbot-BK sets the following registry entries:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Win32 USB Driver = "mvsecn.exe"
HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce\
Win32 USB Driver = "mvsecn.exe"
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Win32 USB Driver = "mvsecn.exe"
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Win32 USB Driver = "mvsecn.exe"
HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce\
Win32 USB Driver = "mvsecn.exe"
W32/Forbot-BK creates a service named "blargh" with the display name "Win32 USB Driver".
The worm runs continuously in the background providing backdoor access to the infected computer through IRC channels.
The backdoor component of W32/Forbot-BK can be used to:
start an FTP and HTTP server.
delete network shares.
start a SOCKS4, SOCKS5, HTTP, TCP and GRE proxy.
list and stop existing processes and services.
download, run and delete files.
modify the registry.
add and delete services.
steal the product keys of popular games and applications.
scan other computers for open ports and attempt to exploit them.
take part in distributed denial of service (DDOS) attacks.
flush the DNS cache.
logoff, reboot and shut down the computer.
W32/Forbot-BK may delete the ADMIN$, IPC$, C$ and D$ network shares.
