Cracking WPA and WPA2 Routers.

Cracking WPA and WPA2 networks is possible due to vulnerabilities in how these protocols handle authentication. Specifically, during the connection process between a device and a router, a 4-way handshake is exchanged to confirm the password and generate encryption keys. This handshake can be captured and cracked offline using dictionary or brute-force attacks, allowing an attacker to test millions of password combinations without alerting the network. If the Wi-Fi password is weak or common, it can be cracked using pre-built wordlists like rockyou.txt. Tools from the Aircrack-ng suite make this process possible. First, airmon-ng is used to put your wireless card into monitor mode, enabling it to listen to all wireless traffic. airodump-ng is then used to locate target access points and capture the 4-way handshake. Once a client connects (or reconnects) to the network, aireplay-ng can perform a deauthentication attack to force the client to reconnect, thereby triggering the handshake exchange. This captured handshake can then be analyzed with aircrack-ng, which compares the hash of passwords in a wordlist to the one captured in the handshake. This process is shared strictly for educational purposes and was tested in a controlled home environment with explicit permission. Unauthorized access to networks is illegal and unethical. These tools are intended to teach network security professionals how to assess the strength of their own Wi-Fi networks and reinforce the importance of using strong, unique passphrases to prevent unauthorized access. Commands Used: 1. Enable monitor mode airmon-ng start wlan0 q 2. Scan for networks airodump-ng wlan0mon 3. Target a network and capture handshake airodump-ng --bssid router_bssid -c channel -w capture wlan0mon 4. Deauthenticate a client to force handshake aireplay-ng --deauth 10 -a router_bssid -c client_mac wlan0mon 5. Crack the captured handshake aircrack-ng -w /usr/share/wordlists/rockyou.txt capture-01.cap
