Airsnort is a free software for recording data packets and calculating keys in 802.11b - wireless networks .
Airsnort is published by a group called "The Shmoo Group" and is available for Linux and Windows operating systems .
There is no direct connection to the IDS Snort program from Sourcefire - despite the similar name and the adopted mascot (Snort: a piglet with a large, snorting nose; Airsnort: the same piglet with wings).
function
Airsnort uses a weak point in the WEP encryption algorithm described by Scott Fluhrer, Itsik Mantin and Adi Shamir . The software uses a network card to passively record data packets from the wireless network, from which the associated key is calculated. It takes a few minutes.
When the first version was released on August 14, 2001 , Airsnort was one of the first end-user programs to exploit this vulnerability.
In the meantime the development of the program has been stopped.
