Reaver exploits these vulnerabilities to recover WPA/WPA2 passphrases. Process: - Identify WPS-enabled networks. - Use Reaver to perform a brute-force attack on the WPS PIN. - Retrieve the WPA/WPA2 passphrase if successful. 3. WPA/WPA2 Handshake Capture and Cracking Capturing the handshake process during a device connection allows attackers to attempt password cracking offline. Procedure: - Use airmon-ng to enable monitor mode. - Capture handshake packets with airodump-ng. - Use aircrack-ng to perform dictionary or brute- force attacks on the captured handshake. 4. Deauthentication Attacks Deauthentication attacks force clients to disconnect from the network, often used to capture handshakes or perform man-in-the-middle attacks. Method: - Use aireplay-ng to send deauth packets. - Capture the handshake when the client reconnects. 5. Evil Twin Attacks An evil twin is a malicious access point that mimics a legitimate Wi-Fi network to intercept user data. Steps: - Set up a rogue AP with same SSID as the legitimate network. - Use tools like airbase-ng to create the fake access point. - Encourage clients to connect, capturing traffic or injecting malicious payloads.
