More Information
W32/Rbot-APS is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-APS 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-APS 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/Rbot-APS may try to terminate security related processes.
When first run W32/Rbot-APS copies itself to <System>\tcpippui.exe.
The following registry entries are created to run tcpippui.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
tcpippui
tcpippui.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
tcpippui
tcpippui.exe
Registry entries are set as follows:
HKCU\Software\Microsoft\OLE
