interesting but i doubt it will give you good impression? can you
imagine that someone has broken your wep , he comes to you and say
"look what we have broken your wep,now we can offer you our services
to secure your networks"

will you accept his service?don't you think its illegal?

there is some validity to that conclusion.  Now, what you do with the

they "offended company" could make your life MISERABLE and cost you TON
of money.  I'd be eager to watch somebody else fight that battle and see
what happens;)

Subject: Legality of WEP Cracking

During an internal business development meeting yesterday we were
discussing
new ways of picking up pen testing clients. One of our junior engineers
suggested that we go war driving, crack some WEP keys and then approach
each
company offering services to make them more secure. The idea was put
down
straight away on the basis that without prior approval we would be
breaking
the law. However, upon further discussion a case was made that (moral
issues
aside) provided we only captured traffic passively, and as long as we
did
not try to connect or send any packets to any devices - would the law be
broken?

Does the law state anywhere that we can not analyse air traffic that is
broadcast into the public domain? (if so surely we would all be breaking
the
law every time we picked up a network other than our own) and is it
against
the law to know someone else's WEP key when they have not made that
information available to you?

What are your thoughts on this?

Kind regards,
