Aircrack is a program which helps you choose strong WPA-PSK passwords by helping you find vulnerabilities in your current network setup.
Recovering lost or forgotten WEP and WPA-PSK keys on wireless networks just got a lot easier with aircrack-ng. The program works by capturing packets sent and received by a wireless WLAN network and recovers the keys through a variety of known working attacks. It runs a standard FMS attack along with some improvements like KoreK attacks.
The program also now features a brand new PTW attack, thus making it much faster compared to other, well-known WEP decoders.
Aircrack-NG is a great set of tools for network auditing and could save you from nosey neighbours or nearby coffee shop patrons looking to spy on your network.
Aircrack-NG also contains many recent improvements including expanded operating system support (Windows XP, Windows Vista, Windows 7 32-bit and 64-bit), new WEP dictionary attacks, support for more wifi cards, new tools available from their web site (airtun-ng, packetforge-ng, wesside-ng, easside-ng, airserv-ng, airolib-ng, airdriver-ng, airbase-ng, tkiptun-ng and airdecloak-ng).
Your wireless LAN wifi driver should be up to date before running this software.
