I just happened to take a look at the IPS report for today on my V8 beta test box and saw something interesting.
Rule ID: 16460
Rule Description: WEB-MISC text/html content-type without HTML - possible malware C&C
Rule Group: Server / HTTP / Common
Packets: 412
The source IP's of these attacks are 64.191.223.35 and 64.191.223.36, which just so happen to be addresses for Commtouch. Due to this, I'm not sure if the AntiSpam reputation information is getting updated or not. Just thought I'd let somebody know.
