Aircrack
From charlesreid1
Aircrack is listed as one of the Kali Top 10 programs.
Aircrack/WEP Cracking: This was my first introduction to Aircrack was using it to crack a WEP-encrypted wireless network. The actual cracking process took about three minutes. It was amazing to be able to do this so easily, and it was a great learning process.
Aircrack/WPA Cracking: This was my next step in learning aircrack: cracking a WPA wireless network. The cracking process was pretty fast, again.
Aircrack/Packet Injection Testing: Before doing packet injection, you may want to run some of these tests.
