We've been seeing UUSee software trigger this alert more often than anything else.

I don't know that there's much that can be done, although I've had to disable alerting on this rule as a result.

Hi Mike. Do you happen to have a pcap of some real UUSee traffic? Might be able to find something to exclude from there.

Thanks

Ugh, sorry Matt, forgot to check back here. I'll see if I can scrounge some.
