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

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.

WepLab is a tool designed to teach how WEP works, what different vulnerabilities it has, and how they can be used in practice to break a WEP protected wireless network. So far, WepLab more than a Wep Key Cracker, is a Wep Security Analyzer designed from an educational point of view. The author has tried to leave the source code as clear as possible, running away from optimizations that would obfuscate it.

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.

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.
