Nim-Backdoor

Overview

The provided Python program, Nim-Backdoor.py, generates a Nim program that operates as a backdoor, allowing remote command execution via a netcat-like session. This tool is designed to work on both Linux and Windows systems. Notably, it has been engineered to bypass popular antivirus software such as Microsoft Defender, Bitdefender, and Kaspersky, making it a stealthy solution for maintaining a persistent connection to a target system.
