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.

anwrap is a wrapper for ancontrol that serves as a dictionary attack tool against LEAP enabled Cisco Wireless Networks. It traverses a user list and password list attempting authentication and logging the results to a file.

WEPWedgie is a toolkit for determining 802.11 WEP keystreams and injecting traffic with known keystreams. The toolkit also includes logic for firewall rule mapping, pingscanning, and portscanning via the injection channel and a cellular modem

AirSnort is a wireless LAN (WLAN) tool which cracks encryption keys on 802.11b WEP networks. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.

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).
