W32/Tilebot-P is a worm and IRC backdoor Trojan for the Windows platform.
W32/Tilebot-P spreads to other network computers by exploiting common buffer overflow vulnerabilites, including:
LSASS (MS04-011) and RPC-DCOM (MS04-012) and by copying itself to network shares protected by weak passwords.
The following patches for the operating system vulnerabilities exploited by W32/Tilebot-P can be obtained from the Microsoft website:
MS04-011
MS04-012
W32/Tilebot-P 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/Tilebot-P includes functionality to access the internet and communicate with a remote server via HTTP.
When first run W32/Tilebot-P copies itself to <Windows>\msconfig32.exe and creates the file <System>\rdriv.sys.
The file rdriv.sys is detected as Troj/Rootkit-W.
