W32/Rbot-API is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-API 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-API 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-API copies itself to <System>\goaw.pif.
The following registry entries are created to run goaw.pif on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Microsoft Intrenet Explorer
goaw.pif
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Microsoft Intrenet Explorer
goaw.pif
The following registry entry is also set:
