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.

WEPCrack is an open source tool for breaking 802.11 WEP secret keys. This tool is is an implementation of the attack described by Fluhrer, Mantin, and Shamir in the paper "Weaknesses in the Key Scheduling Algorithm of RC4".

Lucent Orinoco Client Manager stores SSID and WEP secret for all
known profiles in the Windows registry. The WEP secret is encrypted
but the security relies on the secrecy of the algorithm, not a key.
Compaq does also use the same algorithm.

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.
