More Information
W32/Tilebot-CV is a worm and IRC backdoor Trojan for the Windows platform.
W32/Tilebot-CV spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012), PNP (MS05-039) and ASN.1 (MS04-007), by copying itself to network shares protected by weak passwords and by AOL Instant Messenger.
W32/Tilebot-CV 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-CV includes functionality to access the internet and communicate with a remote server via HTTP.
When first run W32/Tilebot-CV copies itself to <Windows>\msoevc.exe.
The file msoevc.exe is registered as a new system driver service named "Microsoft Regulator", with a display name of "OSdebug" and a startup type of automatic, so that it is started automatically during system startup. Registry entries are created under:
HKLM\SYSTEM\CurrentControlSet\Services\Microsoft Regulator\
