Cross-Platform Reverse HTTP Remote Access Tool
A Python 3–powered open-source project that establishes controlled reverse HTTP communication between host and client across Windows, Linux, Android, and macOS. Built strictly for ethical hacking education.
Backdoor is a cross-platform, open-source Remote Access Tool (RAT) engineered using Python 3. It leverages reverse HTTP requests to create a persistent communication channel between a controlling host and a remote client — bypassing traditional firewall restrictions that block incoming connections.
Unlike conventional access tools, the client initiates all connections, making it adaptable to NAT and firewalled environments. This is the core concept behind many real-world attack vectors — understanding it is critical for any security professional.
Client initiates outbound HTTP requests to the host, circumventing NAT and firewall rules that block inbound connections.
Runs natively on Windows, Linux, macOS, and Android — covering the full spectrum of common operating environments.
Maintains continuous communication channels with reconnect logic, ensuring stable long-term remote access sessions.
Execute shell commands on the client machine through the secure channel, demonstrating full remote control capability.
Built entirely in Python 3 with minimal dependencies — easy to read, audit, modify, and learn from. No black boxes.
Fully open-source codebase. Every line is auditable, customizable, and free to study under ethical use guidelines.
Backdoor was designed with one goal: to make the mechanics of remote access transparent and understandable. Security professionals need to know how attackers think — this project provides a safe, controlled sandbox for exactly that.
Strictly for Educational Use. This tool must only be deployed on systems you own or have explicit written permission to test. Unauthorized access is illegal and unethical.
Learn how reverse connections bypass perimeter security — a fundamental concept in penetration testing.
Examine how Command & Control infrastructure operates over standard HTTP to blend into normal traffic.
Use in controlled lab environments and Capture The Flag competitions to sharpen offensive security skills.
Understanding the attacker's perspective is the fastest path to building better defenses and detection rules.
