Mastering Network Exploitation & Wi-Fi Hacking

In modern mobile security, the network is the new perimeter. This module provides an in-depth exploration of offensive wireless techniques using Android. We will leverage the device’s portability and inherent trust to perform sophisticated attacks, including creating rogue access points, manipulating client behavior, and cracking modern Wi-Fi security protocols like WPA3. You will learn to assess and exploit the very fabric of wireless communications, providing a critical pivot point into wider network infrastructures.

You Will Learn

Part 1: Building Your Android Wireless Attack Rig

• Kernel & Driver Requirements: Understanding monitor mode, packet injection, and which Android Wi-Fi chipsets support them.

• Rooting for Radio Privileges: Why root access is non-negotiable for raw packet manipulation.

• Essential Tool Installation:

  • Installing and cross-compiling native binaries for ARM (aircrack-ng suite, reaver, pixiewps).

  • Leveraging powerful scripting environments (Termux) for a full Linux-style workflow.

  • Utilizing specialized apps (e.g., WiFi Monitor, NetHunter) and their limitations.

Part 2: Advanced Reconnaissance & Network Intelligence

• Passive Footprinting: Using airodump-ng to map all nearby networks and connected clients without sending a single probe.

• Active Probing & Client Hunting: Forcing hidden SSIDs to reveal themselves and identifying preferred networks of nearby devices.

• Target Profiling: Analyzing signal strength, data rates, and client density to select the most viable targets for exploitation.

Part 3: Attacking WPA/WPA2-Personal

• The PMKID Attack: Capturing the PMKID from the initial EAPOL handshake using hcxdumptool and cracking it offline with hashcat. This often requires no client interaction.

• The Traditional Handshake Capture:

  • Deauthentication Attacks: Using aireplay-ng to forcibly deauth clients from a target network, forcing them to reconnect and capture the 4-way handshake.

  • Efficient Wordlist Management: Using combinator, rule-based, and mask attacks with hashcat on a powerful system to crack complex passwords.

• Wi-Fi Protected Setup (WPS) Attacks:

  • Pixie-Dust Attack: Offline brute-force of the WPS PIN using pixiewps on vulnerable routers.

  • Online Brute-Force: Using reaver or bully for routers not vulnerable to Pixie-Dust.

Part 4: Enterprise & WPA3 Exploitation

• The Rogue Access Point (Evil Twin):

  • Creating a perfect clone of a target network with a stronger signal.

  • Techniques for handling 5GHz networks and multiple SSIDs.

• Attacking WPA-Enterprise:

  • Setting up a rogue RADIUS server.

  • Capturing user credentials during the EAP authentication process (e.g., EAP-PEAP, EAP-TTLS).

  • Downgrade attacks to exploit weak EAP methods.

• WPA3 Transition Mode & Dragonblood Vulnerabilities:

  • Exploiting weaknesses in the WPA3’s Dragonfly handshake.

  • Downgrading a WPA3 network to a vulnerable WPA2 mode through resource manipulation.

  • Capturing and cracking the resulting handshake.

Part 5: Post-Connection Exploitation & Man-in-the-Middle (MITM)

• Network Pivoting: Using the compromised Wi-Fi connection as a gateway to attack other devices on the local network.

• Automated MITM Frameworks:

  • Using BetterCAP on Android to perform seamless SSL stripping, DNS spoofing, and session hijacking.

  • Intercepting and manipulating unencrypted traffic.

• HSTS Bypass & HTTPS Interception: Advanced techniques for dealing with encrypted channels, including installing a custom CA certificate on the target device (via social engineering).
