# 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!
