More Information
W32/Codbot-O is a worm with backdoor functionality for the Windows platform.
W32/Codbot-O spreads to other network computers by exploiting common buffer overflow vulnerabilites, including: LSASS (MS04-011), RPC-DCOM (MS04-012) and MSSQL (MS02-039) (CAN-2002-0649). The following patches for the operating system vulnerabilities exploited by W32/Codbot-O can be obtained from the Microsoft website:
W32/Codbot-O 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.
When first run W32/Codbot-O copies itself to <Windows system folder>\dxdmain.exe.
W32/Codbot-O is registered as a new system driver service named "dxdmain", with a display name of "DirectX Graphics" and a startup type of automatic, so that it is started automatically during system startup. Registry entries are created under:
HKLM\SYSTEM\CurrentControlSet\Services\dxdmain\
