Wi-fi Hacking

Understanding and securing Wi-Fi networks has become a crucial aspect of cybersecurity. Whether you are an aspiring ethical hacker, a network administrator, or a tech enthusiast, gaining a solid foundation in Wi-Fi penetration testing is essential for safeguarding your digital environment.

Wi-fi Hacking Basics

Introduction to Aircrack-ng

Aircrack-ng has many tools for all phases of hacking. This course will teach us the most important commands for performing attacks.

Aircrack-ng focuses on different areas of WiFi security:

Monitoring: Packet capture and export data to text files for further processing by third-party tools.
Attacking: Replay attacks, deauthentication, fake access points and others via packet injection.
Testing: Checking WiFi cards and driver capabilities (capture and injection).
Cracking: WEP and WPA PSK (WPA 1 and 2).

Tool
Airmon-ng: Airmon-ng can enable and disable monitor mode on wireless interfaces.
Airodump-ng: Airodump-ng can capture raw 802.11 frames.
Airgraph-ng: Airgraph-ng can be used to create graphs of wireless networks using the CSV files generated by Airodump-ng.
Aireplay-ng: Aireplay-ng can generate wireless traffic.
Airdecap-ng: Airdecap-ng can decrypt WEP, WPA PSK, or WPA2 PSK capture files.
Aircrack-ng: Aircrack-ng can crack WEP and WPA/WPA2 networks that use pre-shared keys or PMKID.

Module 1 - Airmon-ng

Monitor mode is a specialised mode for wireless network interfaces, enabling them to capture all traffic within a WiFi range.

Monitor mode

Checking for interfering processes

monitor mode on a specific channel

Stopping monitor mode

Module 2 - Airodump-ng

Airodump-ng is a tool for capturing packets, specifically targeting raw 802.11 frames.

Scanning Specific Channels or a Single Channel

Scanning 5 GHz Wi-Fi bands

Saving the output to a file

Module 3 - Aireplay-ng

The primary function of Aireplay-ng is to generate traffic for later use in aircrack-ng for cracking the WEP and WPA-PSK keys.

Testing for Packet Injection

Aireplay-ng to perform Deauthentication

Module 4 - Airdecap-ng

Airdecap-ng is a valuable tool for decrypting wireless capture files once we have obtained the key to a network.

Decrypting WEP-encrypted captures

Decrypting WPA-encrypted captures

Module 5 - Aircrack-ng

Aircrack-ng is a powerful tool designed for network security testing, capable of cracking WEP and WPA/WPA2 networks that use pre-shared keys or PMKID.

Module 6 - Connecting methods

Connecting to Wi-Fi networks using Linux involves a few straightforward steps.

Using CLI

Connecting to WEP Networks

Connecting to WPA Personal Networks

Connecting to WPA Enterprise

Module 7 - Finding hidden SSIDs

In WiFi networks, the Service Set Identifier (SSID) is the name that identifies a particular wireless network.

Watching the Hidden Network

Scanning WiFi Networks

Detecting Hidden SSID using Deauth

Bruteforcing Hidden SSID

Bruteforcing all possible values

Bruteforcing using a Wordlist

Module 8 - Bypassing MAC filtering

Bypassing MAC filtering in Wi-Fi networks is a technique used to circumvent a basic security measure that many wireless routers implement.

Scanning Available Wifi Networks

Scanning Networks Running on 5Ghz Band

Disable wlan0 interface

Changing MAC address

Enable wlan0 interface
