Fluxion: The Future of MITM WPA Attacks

Overview

Fluxion is a security auditing and social-engineering research tool designed to retrieve WPA/WPA2 keys from target access points using social engineering (phishing) attacks. It serves as a remake oflinsetby vk496, aiming to offer fewer bugs and enhanced functionality. The tool is compatible with the latest release of Kali Linux (rolling).

While Fluxion's attack setup is primarily manual, it includes an experimental "auto-mode" that handles certain setup parameters automatically.

Installation

Fluxion is actively maintained with regular updates, new features, improvements, and bug fixes. Contributions, including code, documentation, graphics, design suggestions, tutorials, and wiki content, are welcome via GitHub.

Prerequisites

• Operating System: A Linux-based OS is required. Kali Linux 2025.4 is recommended.
• Hardware: An external Wi-Fi card is recommended for optimal performance.

Installation Methods

1. Git Clone (Recommended)

# Using SSHgitclone[email protected]:FluxionNetwork/fluxion.git# Or using HTTPSgitclonehttps://www.github.com/FluxionNetwork/fluxion.git

2. Switch to Tool Directory

cdfluxion

3. Run FluxionExecute the script to check dependencies and prompt for installation of any missing components:

./fluxion.sh

4. Install/Check Dependencies OnlyTo install or check dependencies without running attacks:

./fluxion.sh-i

5. Arch Linux InstallationFluxion is available in the Arch ecosystem:-Manual Build: Navigate to the Arch binary directory and build the package:

cdbin/archmakepkg

• BlackArch Repo: Install directly via the BlackArch repository:

pacman-Sfluxion

Attack Workflow

Fluxion executes a multi-stage attack to compromise a target network:

1. Scan: Identifies a target wireless network.
2. Handshake Capture: Launches theHandshake Snooperattack to capture the necessary handshake for password verification.
3. Rogue AP: Spawns a rogue (fake) access point that imitates the original target.
4. Jamming: Deploys a jammer to deauthenticate all clients from the original AP, luring them to the rogue AP.
5. DNS Spoofing: Spawns a DNS server that redirects all client requests to the attacker's host.
6. Captive Portal: Launches a web server serving a captive portal. This page prompts users to submit their WPA/WPA2 key.
7. Verification: All authentication attempts at the captive portal are checked against the previously captured handshake file.
8. Termination: The attack automatically terminates once a correct key is submitted.
9. Reconnection: The captured key is logged, and clients are allowed to reconnect to the target access point.

For a detailed guide on theCaptive Portalattack, refer to the project's documentation.
