W32/Forbot-AD is a network worm with backdoor Trojan functionality.
W32/Forbot-AD 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-AD copies itself to the Windows System folder as WPSVR.EXE. In order to run automatically each time Windows is started, W32/Forbot-AD sets the following registry entries:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Wireless Provider Server = wpsvr.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce\
Wireless Provider Server = wpsvr.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
Wireless Provider Server = wpsvr.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Wireless Provider Server = wpsvr.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce\
Wireless Provider Server = wpsvr.exe
W32/Forbot-AD creates a service named "LocalSystem" with the display name "Wireless Provider Server".
The worm runs continuously in the background providing backdoor access to the infected computer through IRC channels.
The backdoor component of W32/Forbot-AD may be used to:
delete network shares.
start a SOCKS4 and SOCKS5 proxy.
start an HTTP and TCP proxy.
list and stop existing processes and services.
download and run files.
modify the registry.
add and delete services.
steal the product keys of popular games and applications.
