WEP Hacking Tools

AirSnort

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

BSD-Airtools

bsd-airtools is a package that provides a complete toolset for wireless 802.11 auditing. Namely, it currently contains a bsd-based Wired Equivalent Privacy (WEP) cracking application, called dweputils (as well as kernel patches for NetBSD, OpenBSD, and FreeBSD). It also contains a curses based ap detection application similar to netstumbler (dstumbler) that can be used to detect wireless access points and connected nodes, view signal to noise graphs, and interactively scroll through scanned ap's and view statistics for each. It also includes a couple other tools to provide a complete toolset for making use of all 14 of the prism2 debug modes as well as do basic analysis of the hardware-based link-layer protocols provided by prism2's monitor debug mode.

WEPCrack

WEPCrack is a tool that cracks 802.11 WEP encryption keys by exploiting the weaknesses of RC4 key scheduling.

WAP Attack

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

WEPWedgie

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.
