Fluxion: Automated Phishing Attacks

🛠️ 1 – What is Fluxion?

Fluxion is a popular, open-source security tool for **ethical hacking** and penetration testing. It automates the entire process of an **Evil Twin attack** by combining various scripts and utilities into a single, user-friendly interface. This tool is valuable for cybersecurity professionals and students in controlled lab environments to demonstrate the risks of insecure Wi-Fi networks and phishing attacks. It handles everything from scanning networks to creating a fake access point and a convincing phishing page.

💻 2 – Prerequisites for Using Fluxion

To use Fluxion, you need a specific hardware and software setup, as many internal Wi-Fi cards don't support the required features.

  • Operating System: Fluxion is designed to run on a Linux-based OS, with **Kali Linux** being the most recommended due to its pre-installed tools and compatible drivers.
  • Wireless Adapter: You need a Wi-Fi adapter that supports **monitor mode** and **packet injection**. Popular adapters with Atheros or Realtek chipsets are often used for this.
  • Dependencies: Fluxion requires various tools from the Aircrack-ng suite. The script typically checks and installs these dependencies automatically upon its first run.

🚀 3 – Step-by-Step Guide

Step 1: Installing Fluxion

First, you need to clone the Fluxion repository from GitHub and then run the installer script. 

git clone https://github.com/FluxionNetwork/fluxion.git
cd fluxion
sudo ./fluxion.sh
  • git clone ...: Downloads the Fluxion tool from its official repository.
  • cd fluxion: Navigates into the newly created Fluxion directory.
  • sudo ./fluxion.sh: Executes the main Fluxion script with root privileges.
Cloning and starting Fluxion

Step 2: Selecting an Attack Vector

Once the script starts, it will present a menu and guide you through the process.

  1. Select Wireless Interface: Choose the wireless adapter you want to use for the attack from the list provided.
  2. Scan for Target Networks: Fluxion will automatically start scanning for networks in your area.
  3. Select Target Network: After the scan, a list of available Wi-Fi networks will be displayed. You must choose a legitimate network that you have explicit permission to test.
  4. Select Attack Method: Fluxion offers several attack methods. The most common is the **Evil Twin attack with a captive portal**.

Step 3: Generating and Deploying the Phishing Page

This is where Fluxion automates the complex parts of the attack. It will:

  • **Deauthenticate clients** from the legitimate network to force them to reconnect.
  • **Create a fake access point** with the same name as the target network.
  • **Set up a DHCP and DNS server** to redirect all web traffic to a fake login page (the captive portal).
  • **Serve a fake login page** that looks identical to a real network login portal. Fluxion has templates for various popular Wi-Fi providers.

When a user connects to the fake network and enters their password on the fake page, Fluxion captures the password and stores it for analysis.

Note: This process is strictly for use in a controlled, legal lab environment where you have explicit permission to test systems. Using these tools on unauthorized networks is illegal and unethical.

🛡️ 4 – Ethical Use and Prevention

While Fluxion is a powerful tool, it must be used responsibly.

  • For Defense: Understanding how tools like Fluxion work is the best defense. Users should be taught to verify network authenticity, use a VPN on public Wi-Fi, and never enter sensitive information on unencrypted web pages.
  • For Ethical Hacking: Fluxion allows penetration testers to quickly and effectively demonstrate a network's vulnerability to phishing and social engineering attacks. This highlights the need for stronger security policies and user awareness training.
