More Information
W32/Codbot-R is a worm and IRC backdoor Trojan for the Windows platform.
W32/Codbot-R spreads:
- to other network computers by exploiting common buffer overflow vulnerabilites, including: LSASS (MS04-011), RPC-DCOM (MS04-012), WKS (MS03-049) (CAN-2003-0812) and MSSQL (MS02-039) (CAN-2002-0649)
- by copying itself to network shares protected by weak passwords
W32/Codbot-R 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-R copies itself to <System>\Netmon.exe and creates the clean file <Temp>\terminate.bat.
The file Netmon.exe is registered as a new system driver service named "Netmon", with a display name of "Net Functions Monitoring", a description of "Monitors all active network connections to intercept failures." and a startup type of automatic, so that it is started automatically during system startup. Registry entries are created under:
HKLM\SYSTEM\CurrentControlSet\Services\Netmon\
