Nix 4 Cyber (or n4c) is a framework that uses the Nix package manager to provide reproducible cybersecurity toolkits. The project is organized into categories (e.g., OSINT, Web, Networking), each with a shell.nix file that defines its specific software environment.
This approach ensures that all dependencies are isolated and consistent, allowing users to perform security tasks with a predictable set of tools. The official documentation, including a full tool list and usage examples, is available at n4c.hadi.diy.
To use Nix 4 cyber, you need to have Nix installed on your system. You can then start the shell with the following command:
nix develop --refresh github:nix4cyber/n4c#<toolkit>For example, to start the OSINT environment, you would run:
nix develop --refresh github:nix4cyber/n4c#osintHere are the currently available environments, each providing a curated set of tools for its specific domain:
For web application penetration testing, including directory busting, spidering, and vulnerability analysis. See tools and guides →
A collection of tools for Open Source Intelligence gathering from public sources. See tools and guides →
Utilities for network scanning, traffic analysis, and wireless security. See tools and guides →
Tools focused on password and hash cracking. See tools and guides →
Scripts and tools to help with enumerating and exploiting privilege escalation vectors. See tools and guides →
A suite of tools for digital forensics and file analysis. See tools and guides →
Tools for disassembling and analyzing binaries. See tools and guides →
Utilities to find and extract hidden data within files. See tools and guides →
Add the following in your shell config:
function n4c() {
nix develop --refresh "github:nix4cyber/n4c#${1:-all}" # -c zsh # Escape the $ with ''$ in nix
# mkdir -p /tmp/$(date +"%d%m%y") && cd /tmp/$(date +"%d%m%y") # To create a temporary directory
}Then you can use the following command to start the shell:
