This video tutorial demonstrates how to crack WEP in Windows using AirPcap and Cain and Abel.
Note: It is possible to get this working by using the cheaper “Classic” AirPcap, in conjunction with the old 2.0 Beta Tx Drivers for AirPcap, to enable packet injection capability, but this is entirely unsupported, and is not guaranteed to work. YMMV.
- To begin ARP injections, AirPcap must capture at least 1 ARP request from a system on the target AP. You can usually force this by sending a Deauth to a connected client.
- Make sure you have over 250,000 IVs before attempting to crack the WEP key.
- In my tests, the old AirPcap (silver-grey) appears to perform significantly faster than the new AirPcap (dark-grey). I think it’s about 10x faster.
