Fast Flux signature changes

Regarding the NSP Signature 0x4880ee00 ( Botnet: Connection to Fast Flux Agent Detected ) :

Was this signature recently updated? Since June 9th I have been seeing thousands of Fast flux agent detected alerts. Exporting a list of all Public IPs is also not so easy with the tools provided in the NSM. However investigating the alerts I see that most of these are NTP requests and being blocked on our Internet facing firewall anyway. So this makes me question if this actually is legitimate threat traffic and just a massive amount of new false positives.

Since these alerts are new in my logs. Has the BTP value Or Severity changed for this alert? Is there a way to audit the signature changes or see a changelog when a new Signature database is installed?

According to this paper ( ) NTP can cause Fast Flux false positives. Some feedback from McAfee would be appreciated regarding these alerts.

Hello @wohlebnt_HZA 

Please raise a Service Request with Support team for a false positive analysis. Along with Service Request, kindly attach 5-7 evidence report of the signature triggered. Following document will be helpful -
