Wi-Fi Hacking: A Beginner’s Guide
Wi-Fi hacking involves unauthorized access to wireless networks, exploiting vulnerabilities for malicious or ethical reasons like penetration testing. Techniques include packet sniffing, Evil Twin attacks, de-authentication attacks, brute force, and WPS PIN exploits. Protect networks by using WPA3 encryption, disabling WPS, updating firmware, and employing strong passwords.
Welcome to the "Wi-Fi Hacking" Capture The Flag (CTF)! In this challenge, you'll be testing your knowledge and skills on Wi-Fi security, vulnerabilities, and hacking techniques. This CTF is designed to introduce you to wireless network penetration testing, common vulnerabilities like weak encryption, and tools used by ethical hackers. By the end of this CTF, you will have a better understanding of how Wi-Fi networks can be exploited and how to secure them effectively.
WiFi Security Tips
1. Use a Strong Password – Always use WPA3 (or WPA2 if WPA3 is unavailable) with a complex password.
2. Disable WPS (WiFi Protected Setup) – WPS is vulnerable to brute-force attacks.
3. Change Default Router Credentials – Hackers often exploit default usernames/passwords.
4. Enable MAC Address Filtering – Restricts network access to specific devices.
5. Hide Your SSID (Service Set Identifier) – Prevents your network from being visible to casual users.
6. Use a VPN (Virtual Private Network) – Encrypts your internet traffic for extra security.
7. Keep Firmware Updated – Updates patch security vulnerabilities in routers.
8. Enable Firewall & Intrusion Detection – Many routers have built-in security features.
9. Limit DHCP Range – Assign a specific range of IP addresses to prevent unknown devices from connecting.
10. Monitor Connected Devices – Regularly check your router’s admin panel for unknown devices.
