Aircrack-ng

Scans and recovers Wi-Fi network keys.

If you have forgot the password that you use to connect to Internet using a WiFi connection, you can "reset" the router or use an application like Aircrack-ng to find out. Even though this isn't what most users use this application for.

  Aircrack-ng is part of a group of applications known as packet sniffers, this means, it is an application that intercepts and logs data streams that flow across a net. It will let the user recover the WEP and WPA-PSK key from any wireless connection based on the IEEE 802.11 standard. To manage this it has a group of tools like airbase-ng, Aircrack-ng, airodump-ng, ..., each of these for specific tasks.

  The method implemented by Aircrack-ng is called FMS attack, receiving this name in honor of Fluhrer, Mantin and Shamir that were the first to demonstrate the weakness of WEP ciphering. What's more it includes improvements made to KoreK and others.

  To find out the passwords of wireless webs that aren't properly protects, Aircrack-ng captures the first packs that are transmited by a connection, allowing the user to obtain the passwords and use them to connect to Internet.

  The use of Aircrack-ng requires advanced network knowledge.
