Bah, I'm talking wan IP and service not Lan IP and service, thought I was
clear on that.
What we want is to track the cookie, this MIGHT lead to some mistakes on the
intruders part. Yes, the intruder/s will most likely use someone else's
internet drop to use those identifiable credentials, but what if it's a
internet café? A school library? Another victim? Not only is it fun and
educational to track this info, it's also a possible benefit for others.
Open up the door, give them a cookie and track it's use. Ummm, seems like
there's gonna be some feedback there eh? And bet I would give it a chance to
out weigh any given effort and time. Maybe we need more effort and time?
I have no idea of the resources of the original poster. Besides, the initial
investment is very small. The crux is the tracking of the cookie once it has
been snatched, at it's simplest it's monitoring a log file of the service.
Honestly, this is a small project. Initial setup is under one hour and
checking for the credential use in a log file is automated with a little
bash skill set.
Have fun,

So setup a duplicate of the previously vulnerable wireless

the ip, then get law enforcement and the what I think will be a local ISP
involved.
We are talking about wireless, right? Because in such a scenario, logging
the IP address won't make much of a difference since any IP that the
intruder has would be *one that your DHCP server leased to him*. There is
no ISP to involve here. Unless of course the intruder accesses the
FTP/POP3/whatever server from a different connection, in which case he may
very well be on someone *else's* WLAN and you'll end up expending a great
deal of effort and time (both yours and others') and be no closer to knowing
the identity of your malefactor than you were before.
Yeah, I think hoping that the intruder would be daft enough to access his
Hotmail account is about the best you can hope for here.
