Hi all
We've been asked to perform a vulnerability assessment for a company that
has a Wireless LAN. The W/LAN is running WEP with a random key generated,
rather than a dictionary word.
Are there any tools out there that can brute force a WEP.
Take this example. A person parks the car in the car park and sniffs the
air waves with a product like NetStumbler. He discovers the W/LAN but with
WEP.
Is there a tool he can use to discover the WEP key (possible by brute force)
If there isn't such a tool, how does this sound for an idea.
Run a app that starts at binary 0's and counts upto 128bits of 1's
For each sequence listen to see if there are any sensible packets or even
send out a DHCP discover request to see if you get a reply. This would then
possibly give you the WEP key.
Any comments
Ian....
