🔐 LEAK-FILE: Ethical File Download Trap Tool by Linuxndroid
LEAK-FILE is an advanced yet beginner-friendly ethical hacking tool developed by @Linuxndroid. It simulates a file download trap using a simple Python Flask app. This tool can be a powerful part of your cybersecurity learning, testing environments, or Red Team demonstration setups.
This guide will show you how to clone the tool, host the fake download link on your browser, forward the link publicly using LocalToNet, and share it to simulate a phishing-like trap. The main idea is to understand how attackers might use seemingly harmless download links to gather victim data — so you can defend better in the real world.
⚠️ DISCLAIMER: This tool is strictly for educational, research, and ethical hacking awareness purposes only. Do not use it on real users without informed consent.
🧰 What You’ll Need
- 💻 A Laptop/PC (Windows, Linux, or macOS)
- 🐍 Python 3.11+ installed
- 🌐 Working Internet Connection
- 📦 LocalToNet account for HTTP port forwarding
- 🧠 Basic knowledge of Python and terminal usage
🚀 Step-by-Step Guide to Use LEAK-FILE
📥 Step 1: Clone the GitHub Repository
Start by cloning the official LEAK-FILE GitHub repo:
git clone https://github.com/linuxndroid/LEAK-FILE
cd LEAK-FILE💻 Step 2: Run the Flask App
Now, run the Python app using this command:
python3 app.pyThis will start a Flask web server on localhost:5000.
🌐 Step 3: Open the Web Page Locally
Open your browser and go to:
http://127.0.0.1:5000
You will see a custom file download trap interface.
🌍 Step 4: Publicly Host Using LocalToNet
To share your trap link over the internet, use LocalToNet:
./localtonet http 5000This generates a public URL like:
https://yourname.localtonet.com
🔗 Step 5: Share the Link for Demonstration
Now you can share the link (only in test/lab environments). Anyone visiting the link will see a download file page. With minor customization, you can track visitors' IP, browser, time, and log their interaction with the file download button.
🎯 Why Use LEAK-FILE?
There are several use cases for this tool in ethical hacking and cyber awareness:
- ✅ To demonstrate how dangerous file links work in phishing
- ✅ For teaching students about browser-based traps
- ✅ To simulate Red Team file bait techniques
- ✅ For building and testing your own improved versions
- ✅ To raise awareness among employees or teens about clicking unknown files
This simulation teaches valuable real-world lessons on verifying links, avoiding suspicious downloads, and recognizing red flags in URLs or email attachments.
🎨 Customization Ideas
LEAK-FILE is very lightweight and written in Flask (Python). You can easily modify it to:
- 🎥 Add webcam access permission (browser-based)
- 📍 Capture location/IP using third-party APIs
- 📁 Log the exact time of access and file click
- 🔁 Redirect users to actual download files after logging
- 🕵️ Add decoy file names (e.g., "Free Movie", "Cracked App")
With just a few lines of code, you can enhance the trap for educational cybersecurity workshops or labs.
