3. Reaver

Description:
Reaver is a tool used to recover WPA/WPA2 passphrases by exploiting the WPS (Wi-Fi Protected Setup) feature on routers. It performs a brute-force attack on the WPS PIN until it finds the correct one, allowing the recovery of the passphrase.

Examples:

• 1. Put Interface in Monitor Mode:
     • airmon-ng start wlan0

Explanation: Places the wireless interface wlan0 into monitor mode, which is required for Reaver.

• 1. Start Reaver Attack:
     • reaver -i wlan0mon -b 00:11:22:33:44:55 -c 6 -vv

Explanation: Uses wlan0mon to target the access point with BSSID 00:11:22:33:44:55 on channel 6. The -vv flag increases verbosity to provide more information about the attack progress.

• 1. Specify the WPS PIN:
     • reaver -i wlan0mon -b 00:11:22:33:44:55 -p 12345678

Explanation: Uses the provided WPS PIN (12345678) to attempt to recover the WPA/WPA2 passphrase. This can be useful if the WPS PIN is already known.
