Win32 worm

W32/Sdbot-AE is a worm that spreads on unpatched Windows systems by exploiting the RPC/DCOM vulnerability. The worm also has a backdoor component that allows a remote attacker access to a compromised system via the IRC network.
In order to run automatically when Windows starts up W32/Sdbot-AE creates the following registry entries pointing to the worm binary:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\Windows Service
HKU\Software\Microsoft\Windows\CurrentVersion\Run\Windows Service

The spreading routine of the worm is activated remotely via the IRC control channel.
