WEP Attack

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.

The  requirements:

The network data has been captured by a WLAN card in monitor mode. A network sniffer captures the data to a dumpfile. The use of a Lucent Orinoco Gold Card in combination with Kismet seems to work without any problems.

A working WLAN card is required to work with WepAttack.

WepAttack accepts every dumpfile of pcap structure. Every Tool that can handle dumpfiles in pcap format, as Kismet, Tcpdump or Ethereal does, can be used for sniffing data. Kismet is highly recommended because it offers lots of convenience.
