I've created a signature for capturing file transfers on odd ports (e.g., via netcat) using the magic number of particular file types that I'm interested in. I haven't figured out how to turn this into an event that I can then use to automatically capture the file in a script. Has anyone done something similar? I have had lots of success with basic file-extract in http/ftp/smtp/irc but the non-standard transfers are eluding me.
