RE: Legality of WEP Cracking

That's a good idea about the war chalking Paul, although I haven't seen much
evidence of it locally. As for the use of WEP, it is most definitely still
in use by organisations of all sizes. Whilst parked up in a high street
recently trying to connect to a hot spot, I picked up approx 20 wireless
networks - only 2 were using WPA, the rest (including the council
headquarters and 2 firms of solicitors!) were on WEP. This lack of education
is obviously a huge problem.

Richard

First of all; good post. I haven't yet read all of the responses but some
valid opinions. 

As a UK customer I wouldn't feel to great about someone cracking my WiFi
network but what would happen if someone malicious got their dirty hands on
it? I have also heard of others chalking symbols near cracked zones. 
Perhaps you should go on a walkabout and take lots of photos and use this
material to circulate amongst your geographic potentials! 

Another point, who still uses WEP in business? Clearly some must in order to
get such a response from your posting. I thought WEP was flawed technology!

Kind regards

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,
