## What it is
A small shared library that hides a specified process from tools like ps and lsof on Linux by hooking libc functions via the ld.so preloader mechanism. It is primarily a demonstration of LD_PRELOAD-based process evasion techniques.

## Use cases
- hide a process from ps and top on linux
- demonstrate ld preload process evasion techniques
- test whether monitoring tools can detect hidden processes
- learn how /etc/ld.so.preload hooking works
- simulate malware hiding behavior in a lab

## When to choose
- you need a minimal, well-known example of LD_PRELOAD process hiding for research or red-team demos
- you want to test detection capabilities of Linux monitoring or EDR tooling

## When to avoid
- you need a stealthy or maintained tool for production use - it is a simple educational proof of concept with no license and no recent releases
- you want to actually hide processes for legitimate operational reasons - use proper tooling instead

## Facets
- artifact type: library
- maturity: maintenance
- function: security, reverse-engineering
- domain: security, operating-systems
- platform: c
- tags: ld-preload, process-hiding, rootkit, penetration-testing, evasion, linux
