Hacking WPS Networks with Wifite

Hacking WPS Networks with Wifite

Objective

Learn how to use Wifite, an automated wireless attack tool, to target WPS-enabled networks and understand how to secure such networks against attacks.


Purpose

WPS (Wi-Fi Protected Setup) is a feature that simplifies connecting devices to wireless networks but often contains vulnerabilities that can be exploited. Wifite automates the process of attacking WPS-enabled networks to demonstrate the risks of leaving WPS enabled.


Tools Required

  • Kali Linux (or any Linux distribution with Wifite installed).
  • A Wi-Fi adapter capable of monitor mode and packet injection (e.g., Alfa AWUS036NHA).
  • A test wireless network with WPS enabled.

Lab Topology

  • Kali Linux: Running Wifite.
  • Target Wi-Fi Network: A WPS-enabled test network.

Walkthrough

Task 1: Setting Up Wifite

  1. Verify Wifite Installation:
    • Wifite is pre-installed on Kali Linux. To check:
      wifite --help
      
    • If not installed, install it using:
      sudo apt update && sudo apt install wifite -y
      
  2. Enable Monitor Mode:
    • Identify your Wi-Fi adapter:
      iwconfig
      
    • Enable monitor mode using airmon-ng:
      sudo airmon-ng start <interface>
      

      Replace <interface> with your adapter name (e.g., wlan0).


Task 2: Scanning for WPS Networks

  1. Launch Wifite:
    • Start Wifite:
      sudo wifite
      
  2. Scan for Networks:
    • Wifite will scan for nearby wireless networks.
    • Look for networks with WPS enabled.
  3. Select Target:
    • Choose a WPS-enabled network from the list by entering its number.

Task 3: Attacking the Target Network

  1. Initiate WPS Attack:
    • Wifite will automatically attempt to brute-force the WPS PIN of the target network.
    • Monitor the progress in the terminal.
  2. Capture WPA Key:
    • If successful, Wifite will display the WPA passphrase for the target network.
    • Example output:
      [!] WPA PSK: "password123"
      
  3. Handle WPS Lock:
    • If the WPS PIN attack locks the router:
      • Wait for the lock to reset.
      • Restart Wifite with throttled requests:
        sudo wifite --wps-time 300
        

Task 4: Securing WPS Networks

  1. Disable WPS:
    • Access the router’s administrative interface and disable WPS entirely.
  2. Use Strong WPA2/3 Passwords:
    • Ensure the network password is strong and unique.
  3. Update Router Firmware:
    • Regularly update firmware to patch known vulnerabilities.
  4. Monitor for Suspicious Activity:
    • Use router logs or network monitoring tools to detect unusual activity.

Best Practices

  1. Use Authorized Targets Only:
    • Ensure you have explicit permission to test the network.
  2. Combine Tools for Comprehensive Testing:
    • Use Wifite alongside tools like Aircrack-ng and Reaver for detailed assessments.
  3. Educate Users:
    • Train users on securing home and enterprise networks.
  4. Regularly Audit Networks:
    • Conduct periodic assessments to ensure networks remain secure.

Key Takeaways

  1. Wifite automates the exploitation of WPS vulnerabilities.
  2. Disabling WPS is the most effective way to secure networks against these attacks.
  3. Strong passwords and updated firmware enhance network security.

Troubleshooting Tips

  1. No Networks Detected:
    • Ensure the Wi-Fi adapter is in monitor mode.
    • Verify the adapter supports packet injection.
  2. WPS Lock Issues:
    • Wait for the lock to reset and use throttled requests.
  3. Wifite Crashes:
    • Update Wifite to the latest version:
      sudo apt update && sudo apt upgrade wifite
      

By completing this lab, you now understand how to use Wifite to exploit WPS vulnerabilities and how to secure networks against such attacks.
