+# AIM - AOL instant messenger (OSCAR and TOC)
+# Pattern attributes: good slow notsofast
+# Protocol groups: chat proprietary
+# Wiki: http://www.protocolinfo.org/wiki/AIM
+#
+# Usually runs on port 5190
+#
+# This may also match ICQ traffic.
+# 
+# This pattern has been tested and is believed to work well.

+# See http://gridley.res.carleton.edu/~straitm/final (and various other places)
+# The first bit matches OSCAR signon and data commands, but not sure what
+# \x03\x0b matches, but it works apparently.
+# The next three bits match various parts of the TOC signon process.
+# The third one is the magic number "*", then 0x01 for "signon", then up to four
+# bytes ("up to" because l7-filter strips out nulls) which contain a sequence
+# number (2 bytes) the data length (2 more) and 3 nulls (which don't count), 
+# then 0x01 for the version number (not sure if there ever has been another 
+# version)
+# The fourth one is a command string, followed by some stuff, then the
+# beginning of the "roasted" password
+
+# This pattern is too slow!
