Aim normally connects on tcp 5190 but it can be set to communicate on any
port. Also the data portion of the packet starts with |2A 02|, it may also
start with |2A 05| but this is only for the "unknown" info message, so you
really don't need to capture those packets.
log tcp any any -> any 5190 (content:"|2A 02|";)
log tcp any 5190 -> any any (content:"|2A 02|";)
If I get some time soon I'll try to clean up the rule a little bit. As it
sits you will get some false positives, but it will catch all the aim
traffic on 5190. I put this in because our execs wanted to keep a record of
aim traffic in case we had an info leak, but did not want to ban AIM (trying
to keep the employees happy :)
