Before I go on a wild goose chase, has anyone seen an increase in threat 30419 (RFC2397 Data URL Scheme Usage Detected)?
It seems like these things trip for a while until PA figures out someone's using something novel in a new App. A new application sig comes out and the alerts go away...
I opened a case (00389881) yesterday. They've heard rumblings from customers but hadn't received any pcaps yet.
By chance, I stumbled across someone tripping the sig and called them. They got red-faced when I asked them what they had just done...visited okmagazine.com. Sure enough, I was able to reproduce it and support has a pcap to look at.
