AIRCRACK-NG

Objective

• The goal is to learn how to attack wifi and also learn the various ways how we can prevent ourselves from such attacks

Skills Obtained

• Wifi Pentesting

Tools

• Aircrack-ng suite

• Aircrack-ng is a comprehensive suite of tools designed for auditing wireless networks. It can be used to monitor, attack, test, and crack Wi-Fi networks, making it an essential tool for security professionals and ethical hackers. Here’s an overview of how to install and use Aircrack-ng on a Linux system

Steps

They are 4 steps you need to keep in mind

Turning your adapter to monitor mode with airmon-ng

Scan for the network you want to exploit and save that pcap file with airodump-ng

Send deauth packets to that network your attacking with airepay-ng

Crack the pcap file with aircrack-ng

• Connect your wifi adapter and verify if its connected by typing 'lsusb'

- You can further check connected devices by typing 'iwconfig'

- Start monitor mode by typing the command below

- Its in monitor mode as you can see

- Scan for available networks close to you with the following command

- Focus on the network your trying to attack, save the pcap file and once deauthentication starts, youll sucessully capture the handshake

- Send deauth packets to that network youre trying to attack (using the same mac address as you used in airodump)

- Crack the password using aircrack-ng (But keep it in mind that this takes long depending on the complexity of the password)

USING airgeddon (Evil Twin Attack)

• This attack is much better compared to bruteforcing that usually takes long
• It involves creating a rogue access point where by its the user who actually types in the password for you then you can compare it with your handshake and if its the correct one, then its a success

Tools

• Airgeddon-ng
• A wifi adapter that supports VIFF(Virtual Inerfaces)
