Cracking WEP

ivlist

Tom’s Networking is running a two part series on how to crack WEP. WEP was pretty much broken from the early days of wireless networking. For starters the key length is misleading; a 64-bit key only has 40 unique bits. Some manufactures implemented poor random number generation. The seeds for the numbers are also reused which would never happen in good cryptography. This article covers the techniques the the feds used when they cracked a WEP key in three minutes. This works by grabbing a properly encrypted packet and then constantly sending it back to the access point generating more traffic. The more traffic you can capture the faster you can crack the network. Check out the article. I’ll be trying this out in the future when I get a Prism2 card and that DirecTV antenna wired up.
