Hacking Wireless Networks

Hacking wireless networks explores vulnerabilities in Wi-Fi infrastructures. Wireless networks use radio frequency signals accessible to anyone within range, making them potential targets. Attackers typically begin with reconnaissance to identify available networks using tools like Kismet or Aircrack-ng. They capture information including SSIDs, MAC addresses, signal strength, encryption types, and connected clients. Wireless networks commonly employ these security protocols: - WEP (Wired Equivalent Privacy): Oldest, easily cracked through statistical attacks - WPA (Wi-Fi Protected Access): Improved over WEP but vulnerable to dictionary attacks - WPA2: Stronger using AES encryption, but susceptible to KRACK attacks - WPA3: Latest standard with enhanced protection Common attack methods include: 1. Packet sniffing: Capturing unencrypted wireless traffic 2. Evil twin attacks: Creating rogue access points mimicking legitimate networks 3. Deauthentication attacks: Forcing clients to disconnect and reconnect for capturing handshakes 4. PMKID attacks: Targeting the Pairwise Master Key Identifier 5. Brute force/dictionary attacks: Attempting password guessing 6. WPS (Wi-Fi Protected Setup) attacks: Exploiting PIN vulnerabilities Defensive measures include: - Using WPA3 encryption when available - Implementing strong, complex passwords - Disabling WPS functionality - Enabling MAC filtering - Reducing signal broadcast range - Regular firmware updates - Network segmentation - Using VPNs for sensitive communications Forensic analysis of wireless attacks involves examining access point logs, network traffic captures, and system logs to identify unauthorized access attempts. As a CEH professional, understanding these vulnerabilities helps organizations implement appropriate countermeasures to protect wireless infrastructure from unauthorized access.
