## What it is
Reptile is a Linux kernel module (LKM) rootkit written in C that provides privilege escalation, file/process/network connection hiding, persistence, and a port-knocking backdoor with a full TTY shell. It is intended solely for security research, education, and defensive testing in controlled environments.

## Use cases
- study how linux kernel rootkits work
- test rootkit detection tools
- security research on lkm rootkit techniques
- red team lab training environment
- analyze rootkit hiding techniques
- build defensive detections for kernel rootkits

## When to choose
- you need a well-known reference rootkit for malware analysis or detection research
- you are running an isolated lab VM to study kernel-level hiding and backdoor techniques
- you want to evaluate antivirus or EDR detection of LKM rootkits

## When to avoid
- you want to secure a production system - this is a rootkit, not a defense tool
- you lack explicit authorization for the target system
- you need a supported or licensed project - it has no license and dual-use legal risk
- you run non-Linux or unsupported kernel versions

## Facets
- artifact type: library
- maturity: active
- function: security, cryptography
- domain: security, operating-systems, penetration-testing
- platform: cpp
