Wired Equivalent Privacy (WEP) is a security protocol for 802.11-based wireless networks.

Wired Equivalent Privacy (WEP) is a security protocol for 802.11-based wireless networks. WEP uses the RC4 stream cipher. The protocol is now known to be flawed, and breaking into networks that use it is considered trivial.

I have been working on decrypting a WEP .cap file using crunch. It has 1268 IVs. I am wondering: Can I get a clue from the captured file to speed the process of brute-forcing? If not, what other ways I can try to decrypt the packet? It is a…

Does use of WEP only open the network to attacks in proximity of the router?

I'm learning about security, and discovered my family's router was set to use WEP, with WPS enabled. I've fixed that, but I couldn't give a great answer for why it was necessary, given that we live in a suburban neighborhood with friendly neighbors…

So recently I managed to implement the Caffe-Latte attack in python. I got stuck for two weeks because the final ICV wouldn't match. After some digging around I found that airbase-ng (which already implemented the Caffe-Latte attack in C) used a…

What will happen if WEP reuses a challenge?

What will happen if a WEP authentication challenge string is reused? If the access point ran out of unique random numbers and reused one then what would happen? I'd think that if challenges were reused then an eavesdropper could intercept the…

Regarding number of packets needed to crack WEP

One of the major weaknesses of WEP is a short 24-bit IV, which means that only 224 packets are needed to exhaust all IVs. 224 translates to about 16.5 million IVs (or packets for that matter). Although we need this many packets to start having…

WEP keystream extraction

After having captured multiple packets with repeated IVs you can perform cipher1 XOR cipher2 which is the same as having cleartext1 XOR cleartext2, and performing cipher1 XOR cleartext1 gives you the keystream... but how can you separate those XORed…
