7 # Usually runs on port 5190
9 # This may also match ICQ traffic.
11 # This pattern has been tested and is believed to work well.
14 # See http://gridley.res.carleton.edu/~straitm/final (and various other places)
15 # The first bit matches OSCAR signon and data commands, but not sure what
16 # \x03\x0b matches, but it works apparently.
17 # The next three bits match various parts of the TOC signon process.
18 # The third one is the magic number "*", then 0x01 for "signon", then up to four
19 # bytes ("up to" because l7-filter strips out nulls) which contain a sequence
20 # number (2 bytes) the data length (2 more) and 3 nulls (which don't count),
21 # then 0x01 for the version number (not sure if there ever has been another
23 # The fourth one is a command string, followed by some stuff, then the
24 # beginning of the "roasted" password
26 # This pattern is too slow!
