: Only target assets, networks, and systems that you legally own or have written authorization to test.
In its early days, GitHub was primarily used by developers to host and manage their open-source projects. The platform provided a simple, user-friendly interface for creating and managing Git repositories, making it easy for developers to collaborate on software projects. As the platform gained popularity, GitHub began to add new features, such as issue tracking, project management tools, and code review capabilities.

A dynamic numbered terminal selection menu will load. Below is the workflow to create a reverse TCP executable for Windows:
: It uses various encoding and obfuscation techniques to help payloads evade signature-based detection by antivirus programs. fatratgithub
Generates lightweight scripts designed to execute entirely in memory.
It natively links with the Metasploit Framework, automating the setup of listener nodes (reverse shells) to catch the incoming connection from a target machine [1].
While static signatures can be bypassed via encoding, the behavior of a Meterpreter shell (e.g., lsass.exe dumping, unexpected network connections from powershell.exe ) will be caught by modern EDR solutions like CrowdStrike, Microsoft Defender for Endpoint, or SentinelOne.
Enter your local IP address (the IP of your attacking machine). : Only target assets, networks, and systems that
Users can generate payloads targeting Windows, Android, macOS, and Linux operating systems [1].
Using this tool on systems without explicit permission is illegal. Its purpose is to demonstrate how malicious payloads are constructed, allowing security defenders to build more robust detection mechanisms. Common Issues and Active Development
TheFatRat can go beyond simply generating stand-alone Trojans. It can inject malicious code into legitimate files, a technique known as backdooring:
FatRat relies on social engineering. The malware usually arrives disguised as an invoice, a resume, or a "free software crack." Train employees never to run executable files from unknown senders. As the platform gained popularity, GitHub began to
The FatRat is an incredibly potent utility. It must be used for authorized penetration testing, security research, and educational purposes. Running unauthorized payloads on infrastructure or devices you do not own—or do not have explicit, written permission to test—is a severe violation of cyber laws globally (such as the Computer Fraud and Abuse Act in the US). Proactive Next Steps
On the other hand, the features that make it great for testing—specifically its —make it a highly attractive weapon for cybercriminals. The tool has been discussed widely in underground forums and is often a first step for novice "script kiddies" to launch attacks. Security research has documented that malware samples created by TheFatRat, which initially show no detections on services like VirusTotal, can eventually be flagged, but the window of zero-detection can be significant, posing a serious risk.
: Creates executables for .exe (Windows), .apk (Android), and .macho (Mac).
Only run it in an isolated virtual machine (VMware or VirtualBox) with no internet access or in a controlled lab environment. Never point it at a real IP address.
Infected machines can become part of a botnet, used to launch DDoS attacks on government or corporate websites.
