More Information
W32/Tilebot-CH is a worm and IRC backdoor Trojan for the Windows platform.
W32/Tilebot-CH can spread via common buffer overflow exploits including LSASS
(MS04-011), RPC-DCOM (MS04-012), and ASN.1 (MS04-007) and to weakly protected
network shares.
W32/Tilebot-CH 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-CH includes functionality to access the internet and communicate
with a remote server via HTTP.
When first run W32/Tilebot-CH copies itself to <Windows>\rasdfgl32.exe.
The following registry entry is created to run rasdfgl32.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
rasdfgl32
<Windows>\rasdfgl32.exe
W32/Tilebot-CH sets the following registry entries, disabling the automatic
