15 minutes to crack a WEP key

As if you needed any further warnings that WEP is rubbish, here is a
short demo of a wireless WEP attack. This is a very interesting
technique, where packets are injected to the access point, making it
release weak IVs. You’ll think twice about WEP after this! This is
really important: even though there is not much traffic on the AP, we
generate our own by replaying a single packet over and over again! more
