Aircrack-ng
What is Aircrack-ng?
Aircrack-ngAn open-source Wi-Fi auditing suite used to capture 802.11 traffic and recover WEP and WPA/WPA2 pre-shared keys from handshakes.
Aircrack-ng is a free, GPL-licensed collection of command-line tools maintained by Thomas d'Otreppe and the Aircrack-ng team for assessing the security of Wi-Fi networks. The suite includes airmon-ng to put adapters in monitor mode, airodump-ng to capture packets, aireplay-ng to inject deauthentication and ARP-replay frames, and aircrack-ng itself to crack WEP keys or run dictionary attacks against WPA/WPA2 four-way handshakes. It is the de facto reference toolkit for wireless penetration testers and is bundled in Kali Linux and Parrot OS. Defenders use it to validate strong passphrases, detect rogue access points, and confirm the migration to WPA3-SAE.
● Examples
- 01
Capturing a WPA2 handshake with airodump-ng and cracking it offline against a wordlist.
- 02
Using aireplay-ng to inject deauth frames during a red-team wireless engagement.
