Infiltrating Wi-Fi Networks: Software and Techniques Without a Router

Wi-Fi has become an integral part of our daily lives. From homes, workplaces, and cafes, to other public places, Wi-Fi networks provide fast and easily accessible internet connections.

While there are many software and techniques that can be used for hacking Wi-Fi passwords, it’s important to understand the risks and ethics behind these actions:

Infiltrating Wi Fi Networks
  • Legality: Hacking Wi-Fi without a permit is illegal in many countries and can result in severe penalties, including fines and imprisonment.
  • Security: Accessing a network without permission can open up security risks for users and the network. Personal information and sensitive data can be exposed.
  • Ethics: Unauthorized hacking violates the privacy and trust of others. This is not only a legal issue, but also a moral issue.

This article aims to better understand the software and techniques for hacking Wi-Fi passwords without accessing the router. However, it is important to emphasize that this information is provided for educational purposes and increased security awareness. Bardimin does not support or encourage illegal or unethical actions. Bardimin’s main goal is to help readers understand how to protect their Wi-Fi networks and improve their online security.

Aircrack-ng

Aircrack-ng is one of the most well-known tools in the world of Wi-Fi network security. First released in 2006 as part of a network security suite, Aircrack-ng has become the de facto standard for security researchers and ethical hackers looking to test the security of Wi-Fi networks. Its popularity is driven by its powerful ability to decrypt WEP and WPA-PSK passwords and its support for various platforms such as Linux, Windows, and macOS.

Aircrack-ng works with two main steps:

  1. Collecting Data Packets: Aircrack-ng uses the monitor mode of the wireless network adapter to capture all packets sent over the target Wi-Fi network. This mode allows the adapter to capture data packets without connecting to the network.
  2. Brute-force attack: After enough data packets have been collected, Aircrack-ng uses the brute-force method to try various password combinations until it finds the correct one. On the WEP network, Aircrack-ng uses statistical analysis to crack encryption keys. On the WPA/WPA2 network, Aircrack-ng performs a brute-force attack on the captured 4-way handshake.

Basic Tutorial on Using Aircrack-ng

Here are the basic steps to use Aircrack-ng:

  1. To install Aircrack-ng on Linux (for example, Debian-based distributions such as Ubuntu), open a terminal and run the following command:
sudo apt-get update
sudo apt-get install aircrack-ng
  1. Enable monitor mode on your Wi-Fi adapter. For example, if your adapter is wlan0, run the following command:
sudo airmon-ng start wlan0
  1. This will activate monitor mode and change the interface name to wlan0mon (or something similar).
  2. Use airodump-ng to scan the network and collect data packets. Run the command:
sudo airodump-ng wlan0mon
  1. This will display a list of Wi-Fi networks around you. Record the BSSID and channel of the target network.
  2. Start collecting packets from the target network and save them to a file:
sudo airodump-ng --bssid [BSSID] -c [Channel] -w capture wlan0mon
  1. Replace [BSSID] and [Channel] with your target network information. This will save the collected data to a file named capture.
  2. Once you’ve caught the handshake, use Aircrack-ng to perform a brute-force attack:
sudo aircrack-ng -w [wordlist] -b [BSSID] capture-01.cap
  1. Replace [wordlist] with the path to the list of passwords you want to use, and [BSSID] with the BSSID of the target network. capture-01.cap is a previously created packet capture file.
  2. Aircrack-ng will start trying password combinations from the wordlist you provided. If the password is found, it will be displayed on the screen.

Usage Examples

Suppose you want to test the security of your own Wi-Fi network that uses WPA2. You can use an existing wordlist or create a list of passwords that might be used. Once you’ve successfully collected a handshake and run a brute-force attack, you can tell if your password is strong enough or needs to be changed.

With a better understanding of how Aircrack-ng works, you can take more effective steps to protect your Wi-Fi network from potential threats.

Wireshark

Wireshark is one of the most powerful and popular tools for analyzing networks. As a network protocol analyzer, Wireshark allows users to capture and examine data moving through the network in real time. Its main functions include:

  • Capturing Packets: Captures data packets sent and received over the network.
  • Filtering Packets: Filter packets based on various criteria such as IP address, protocol, and more.
  • Analyzing Protocols: Describes and displays the details of the various network protocols used in data packets.
  • Identifying Issues: Detects network issues, such as high latency, packet loss, and network attacks.
  • Forensic Analysis: Assist in network forensic analysis to investigate security incidents.
