Aircrack-ng

Aircrack-ng will help to display any activity of your or someone else's Wi-Fi channel. With this software package you can test the network for various vulnerabilities, tracking all traffic movements (network audit). After all, modern encryption algorithms are far from ideal to provide maximum security.

Among the main features are WEP and WPA-PSK keys, including their recovery. The program contains a number of useful tools. For example, Airodump-ng will help with the analysis of data packets and give you full information about the network. And wesside-ng will restore the WEP keys automatically. Other tools can be found on the developers' website.

Speaking of implicit advantages, it is worth mentioning that the unfortunate vulnerability in OpenSSL (Heartbleed) did not affect the algorithm of the program.

Before proceeding to install the utility, you should carefully study the official documentation describing the network commands and additional functions. The program is focused on wireless networks only.
