More Information
W32/Rbot-ARO is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-ARO 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), Veritas (CAN-2004-1172), MSSQL (MS02-039) (CAN-2002-0649) and ASN.1 (MS04-007).
W32/Rbot-ARO 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-ARO copies itself to <System>\cnsg.pif.
The following registry entries are created to run cnsg.pif on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Microsoft Intrenet Explorer
cnsg.pif
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Microsoft Intrenet Explorer
cnsg.pif
The following registry entry is set:
HKCU\Software\Microsoft\OLE
Microsoft Intrenet Explorer
cnsg.pif
The following patches for the operating system vulnerabilities exploited by W32/Rbot-ARO can be obtained from the Microsoft website:
