WepAttack WLAN 802.11 WEP Key Hacking Tool


WepAttack is a WLAN open source linux WEP key hacking tool for breaking 802.11 WEP keys using a wordlist based dictionary attack.

WepAttack   WLAN 802.11 WEP Key Hacking Tool

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.

What is a WEP Key? Wired Equivalent Privacy (WEP) is a security algorithm for IEEE 802.11 wireless networks. Introduced as part of the original 802.11 standard ratified in 1997, its intention was to provide data confidentiality comparable to that of a traditional wired network.[1] WEP, recognizable by its key of 10 or 26 hexadecimal digits (40 or 104 bits), was at one time widely in use and was often the first security choice presented to users by router configuration tools.

It’s kinda old now, but you still find it used in situations where the equipment isn’t updated very often (old control systems, CCTV, old point of sale systems etc).

Using WepAttack WEP Key Hacking Tool WepAttack needs a dumpfile for attacking networks. If the network data is captured byKismet a dumpfile is generated automatically. This file is in format “Kismet-[date]-[no].dump“ and can be passed to WepAttack.


wepattack -f dumpfile [-m mode] [-w wordlist] [-n network] -f dumpfilenetwork dumpfile to read from -m moderun WepAttack in different modes. If this option is empty, all modes are executed sequentially (default) 64WEP 64, ASCII mapping 128WEP128, ASCII mapping n64WEP64, KEYGEN function n128WEP128, KEYGEN function -w wordlistwordlist to use, without any wordlist stdin is used -n networknetwork number, can be passed to attack only one network. Default is attacking all available networks (recommended) Example on how to use WEP Hacking Tool
