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.

First airodump is started to gather the packets; herefore channel and MAC-filter are asked, yet the user does not need to know them per se (instead 0 and p may be inputted respectively). Then, AirCrack is started, the file just created by airodump is accessed, a 0 needs to be entered and the program determines the key.

Tools such as AirSnort or Aircrack-ng can quickly recover WEP encryption keys. [139] Because of WEP's weakness the Wi-Fi Alliance approved Wi-Fi Protected Access (WPA) which uses TKIP. WPA was specifically designed to work with older equipment usually through a firmware upgrade. Though more secure than WEP, WPA has known vulnerabilities.

Typically, illegal Internet wiretapping is conducted via Wi-Fi connection to someone's Internet by cracking the WEP or WPA key, using a tool such as Aircrack-ng or Kismet. [39] [40] Once in, the intruder relies on a number of potential tactics, for example an ARP spoofing attack, allowing the intruder to view packets in a tool such as Wireshark ...
netsniff-ng is a free Linux network analyzer and networking toolkit originally written by Daniel Borkmann. Its gain of performance is reached by zero-copy mechanisms for network packets (RX_RING, TX_RING), [ 3 ] so that the Linux kernel does not need to copy packets from kernel space to user space via system calls such as recvmsg() .
