More Information
W32/Forbot-CE is a network worm with backdoor functionality.
When first run W32/Forbot-CE copies itself to the Windows system folder and creates the following registry entries to run automatically on startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
MSN ang = "cssrss.exe"
HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce\
MSN ang = "cssrss.exe"
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
MSN ang = "cssrss.exe"
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
MSN ang = "cssrss.exe"
HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce\
MSN ang = "cssrss.exe"
Each time W32/Forbot-CE runs it tries to connect to a remote IRC server and join a predefined channel. W32/Forbot-CE then listens on the channel for instructions specified by a remote intruder,
W32/Forbot-CE attempts to spread to network computers using various exploits and may try to delete network shares.
