More Information
W32/Rbot-AEI is a worm with IRC backdoor functionality for the Windows platform.
W32/Rbot-AEI runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.
W32/Rbot-AEI is capable of spreading to computers on the local network protected by weak passwords after receiving the appropriate backdoor command.
W32/Rbot-AEI may also spread by exploiting the following vulnerabilities for which patches can be obtained from the Microsoft website :
MS04-011
MS04-012
MS03-049
MS02-039
When first run W32/Rbot-AEI copies itself to <Windows system folder>\cgywin32.exe.
The following registry entries are created to run cgywin32.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Cgywin
cgywin32.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Cgywin
cgywin32.exe
The following registry entry is set:
HKCU\Software\Microsoft\OLE
Cgywin
cgywin32.exe
