W32/Tilebot-X 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) and by copying itself
to network shares protected by weak passwords.
W32/Tilebot-X 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-X includes functionality to :
- setup a SOCKS4 server
- enumerate all drives and processes on the infected computer
- access the internet and communicate with a remote server via HTTP
- create new AOL Instant Messenger profiles
- perform port scanning
- steal information including POP3, Hotmail usernames and passwords
as well as tfrom the Protected Storage area
W32/Tilebot-X createsalso the file \rofl.sys. The file rofl.sys is
detected as Troj/RKPort-Fam.
The following patches for the operating system vulnerabilities
exploited by W32/Tilebot-X can be obtained from the Microsoft website:

When first run W32/Tilebot-X copies itself to <Windows>\smrss.exe and
creates the file <System>\rofl.sys.
The file rofl.sys is detected as Troj/RKPort-Fam.
The file smrss.exe is registered as a new system driver service named
"Windows Smrss Service", with a display name of
"Windows Smrss Service" and a startup type of automatic, so that it
is started automatically during system startup. Registry entries are
created under:
