Of course this only applies to the .com domain (and with a slight change, the .net domain). Do you have any signatures for the other domains? We had quiet a few on Bleeding, but these triggered not only on responses from the root-servers reporting the authoritative gTLD and ccTLD servers, but also on responses from those TLD servers on who is the authoritative name server and on responses from those name servers. We finally removed them again a couple day ago.
No, I don't have any more - I want to get some feedback before rolling out additional signatures for other domains. Also, we're going to completely miss if the attacker decides to just poison google.com instead of the whole TLD.
You said you're not getting false positives. Have you actually caught TRUE positives with this sig?
