This tool is released as a proof-of-concept to demonstrate a weakness in the
LEAP protocol. LEAP is the Lightweight Extensible Authentication Protocol,
intellectual property of Cisco Systems, Inc. LEAP is a security mechanism
available only on Cisco access points to perform authentication of end-users
and access points. LEAP is written as a standard EAP-type, but is not compliant
with the 802.1X specification since the access point modifies packets in
transit, instead of simply passing them to a authentication server (e.g.
RADIUS).

WEP Key Recovery (WEPKR) is an add-on for CommView for WiFi designed for recovering WEP encryption keys for WEP-protected 802.11 a/b/g wireless networks. This application takes advantage of a number of weaknesses found in the WEP encryption algorithm. By analyzing a few hundred thousand data packets captured by CommView for WiFi, WEPKR can obtain a 64-, 128-, 152-, or 256-bit key.

WepAttack is a WLAN open source Linux tool for breaking 802.11 WEP keys. This tool is based on an active dictionary attack that tests millions of words to find the right key. Only one packet is required to start an attack.

We were able to extend Klein's attack and optimize it for usage against WEP. Using our version, it is possible to recover a 104 bit WEP key with probability 50% using just 40,000 captured packets. For 60,000 available data packets, the success probability is about 80% and for 85,000 data packets about 95%. Using active techniques like deauth and ARP re-injection, 40,000 packets can be captured in less than one minute under good condition. The actual computation takes about 3 seconds and 3 MB main memory on a Pentium-M 1.7 GHz and can additionally be optimized for devices with slower CPUs. The same attack can be used for 40 bit keys too with an even higher success probability.
