[Snort-sigs] UDP Strangeness Signatures -- ISC

Subject: [Snort-sigs] UDP Strangeness Signatures -- ISC
Date: Sat, 11 Dec 2004 00:29:43 -0500
The intrepid Incident Handlers at http://isc.sans.org are on the trail of the recent UDP strangeness noted in the last couple days Diary Entries.

http://isc.sans.org/diary.php?date=2004-12-10

Erik Fichtner put great effort into writing signatures to detect this very complex traffic they're investigating. They've asked that we distribute these rules and ask that you report the details of any hits.

The signatures are posted in the current bleedingsnort.com ruleset. We'll keep them there until ISC has enough information.

PLEASE!!! Report any hits. They don't require disclosing any sensitive information to do so.

The signatures are available for review here:
http://www.bleedingsnort.com/cgi-bin/viewcvs.cgi/Stable/ISC_RESEARCH_UDP_Frags

Again, they're posted to the main rulesets so update if you're willing to help out.
