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.

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.

WPA Cracker is a cloud cracking service for penetration testers and network auditors who need to check the security of WPA-PSK protected wireless networks.

WPA-PSK networks are vulnerable to dictionary attacks, but running a respectable-sized dictionary over a WPA network handshake can take days or weeks. WPA Cracker gives you access to a 400CPU cluster that will run your network capture against a 135 million word dictionary created specifically for WPA passwords. While this job would take over 5 days on a contemporary dual-core PC, on our cluster it takes an average of 20 minutes, for only $17.

First release of chopchop. WEP cracker which uses the AP to decipher packets. Easiest one are ARP's. Takes 10-20s. Included within patches for wlan-ng to inject packets in monitor mode (I'll try to do hostap for the next release). That's about it. Bits and pieces are missing here and there (only decodes IP/ARP traffic), but it's pretty complete. Bug reports are welcome.
