More Information
W32/Rbot-ATI is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-ATI spreads to other network computers by exploiting common buffer overflow
vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012), WKS (MS03-049)
(CAN-2003-0812), MSSQL (MS02-039) (CAN-2002-0649), PNP (MS05-039) and ASN.1 (MS04-007) and by copying itself to network shares protected by weak passwords.
W32/Rbot-ATI 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/Rbot-ATI copies itself to <System>\crease.exe.
The following registry entries are created to run crease.exe on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Windows Media Updater
crease.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Windows Media Updater
crease.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Windows Media Updater
crease.exe
Registry entries are set as follows:
HKLM\SOFTWARE\Microsoft\Ole
EnableDCOM

HKLM\SYSTEM\CurrentControlSet\Control\Lsa
