I'm seeing a lot of our internal boxes supposedly attacking 18.104.22.168, one of Windows update servers, via sig 5403. The context buffer doesn't have any data. Is any one else seeing false positives with this signature?
We are aware of a false positive situation, but we need more information to diagnose the problem customers are seeing. If possible, could you capture some iplogs of the false alarms and send them to email@example.com.
