TypePacket sniffer and injector; WEP encryption key recovery

Aircrack-ng is a network software suite consisting of a detector, packet sniffer, WEP and WPA/WPA2-PSK cracker and analysis tool for 802.11 wireless LANs. It works with any wireless network interface controller whose driver supports raw monitoring mode and can sniff 802.11a, 802.11b and 802.11g traffic. The program runs under Linux, FreeBSD, macOS, OpenBSD, and Windows; the Linux version is packaged for OpenWrt and has also been ported to the Android, Zaurus PDA and Maemo platforms; and a proof of concept port has been made to the iPhone.

In April 2007 a team at the Darmstadt University of Technology in Germany developed a new attack method based on a paper released on the RC4 cipher by Adi Shamir. This new attack, named 'PTW', decreases the number of initialization vectors or IVs needed to decrypt a WEP key and has been included in the aircrack-ng suite since the 0.9 release.

Aircrack-ng is a fork of the original Aircrack project. It can be found as a preinstalled tool in many security-focused Linux distributions such as Kali Linux or Parrot, which share common attributes as they are developed under the same project (Debian).


The aircrack-ng software suite includes:

Name Description
aircrack-ng Cracks WEP keys using the Fluhrer, Mantin and Shamir (FMS) attack, PTW, Korek, dictionary attacks, and WPA/WPA2-PSK using dictionary attacks.
airdecap-ng Decrypts WEP or WPA encrypted capture files with known key.
airmon-ng Places different cards in monitor mode.
aireplay-ng Packet injector (Linux, and Windows with CommView drivers).

airtun-ng Virtual tunnel interface creator.
packetforge-ng Creates encrypted packets for injection.
ivstools Tools to merge and convert.
