So ok...I have udp port 135 block anyways, but I wanted to see if this would fly...so far this hasn't seemed to work: alert udp $EXTERNAL_NET any -> $HOME_NET 135 (msg:"Popup Spam Attempt"; content:"|F8 91 7B 5A 00 FF D0 11 A9 B2 00 C0 4F B6 E6 FC|";)
I have just looked at some of my automatically generated signatures (using Honeycomb[1] and honeyd) for UDP port 135 and this looks correct. I do see some signatures that do not contain the last byte (0xFC), but otherwise they match perfectly. It should work.
