Re: Legality of WEP Cracking

Hi Richard;

Pen testing without permission is dangerous. I would advise against it
both from a marketing an a legal perspective (IANAL).

Marketing: What you are proposing stinks like a protection racket. I
know that is not your intent, but that is what a customer is going to
think. Wardriving, looking for WEP connections may be OK from this
perspective provided that you don't do any further action (like key
cracking). I would also say that you may be able to get further
permission to demo the problems, and then it would be OK first. (Just
ask first ;-) )

Legal (IANAL): Whenever you crack anything without permission you may be
argued to be tresspassing. This may mean that you have to plead your
case in court right or wrong. If you want a legal opinion, however, I
would suggest hiring an attourney.

Be careful, contact an attourney, and also run mock sales pitches by
others who are not technically savvy to see how they respond.

I am leaving the original email below as a point of reference to the
proposal I am warning about.

Best Wishes,
Chris Travers
