SID 1447 - MISC MS Terminal server request (RDP)
AFAIK, this sig is for simple Terminal Server connections, and nowhere does it mention 'malformed' requests. This rule works without even being logging in, but simply the Remote Client talking to the TS as telnetting doesn't produce the same alert. I just tested on a production server by connecting and not logging in or touching anythign at that point, and I received a single alert as usual. Proceeding to use TS produces 0 extra alerts. hth, John -----Original Message----- From: Parker, Ian [mailto:parker.ian () syncrude com] Sent: Friday, December 20, 2002 1:28 PM To: 'snort-users () lists sourceforge net' Subject: [Snort-users] MS Terminal Server Requests I was wondering who created the experimental Snort rule for detecting malformed RDP packets in an MS terminal server request, SID 1447, and how they came up with that particular payload. The reason I'm curious is that every RDP packet to my terminal servers has this payload, so the rule gets triggered all the time.
