[Bro] Quick smtp-url-extraction question

I submitted a pull request last week for this. You could technically grab the script and run it. Since I’m not part of the Bro team though, I can’t promise that this will continue to work.


I run a variation of this script in my production environment right now. Keep in mind that it is normally a bad plan to extend an internal Bro module. Since there’s a pretty high demand for it, if you’d like to modify this to not extend the internal SMTP modules and be separate, it is a relatively short task (about 15 minutes).

Lastly, this is provided as-is with no warranty, etc. etc.

I just wanted to add that I think that script that logs SMTP URLs would get a lot of use in our environment as well.  It’s been an elusive data point, but one we really would like to have.  We’ve been having high-level discussions on how to implement something that does this exact process in our office, so I’d be very interested in using this script once it’s ready as well.

Much of that should be handled automatically by the mime analyzer (I'm not sure of the limits of that offhand).

I'll see if I can get to it soon.
