More Information
W32/Rbot-ART is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-ART spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: WKS (MS03-049) (CAN-2003-0812), Veritas (CAN-2004-1172) and ASN.1 (MS04-007) and by copying itself to network shares protected by weak passwords.
W32/Rbot-ART 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-ART copies itself to <System>\tcpippui32.exe.
The following registry entries are created to run tcpippui32.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
tcpippui32
tcpippui32.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
tcpippui32
tcpippui32.exe
Registry entries are set as follows:
HKCU\Software\Microsoft\OLE
tcpippui32
tcpippui32.exe
HKLM\SOFTWARE\Microsoft\Ole

HKLM\SYSTEM\CurrentControlSet\Control\Lsa
