## What it is
Singularity is a stealthy Linux kernel module (LKM) rootkit targeting modern 6.x kernels, using ftrace-based syscall hooking to hide processes, files, network connections, and itself. It is a proof-of-concept offensive security research tool that also demonstrates evasion of eBPF-based runtime security tools, LKRG, audit, and memory forensics mechanisms.

## Use cases
- study ftrace-based syscall hooking on modern kernels
- test EDR and eBPF runtime security tools like Falco and Tracee against kernel rootkits
- research rootkit stealth techniques for red team engagements
- evaluate LKRG and audit subsystem detection capabilities
- learn Linux kernel module development and hooking internals
- demonstrate process, file, and network connection hiding in a lab environment

## When to choose
- you need a modern, actively maintained kernel rootkit PoC for 6.x kernels
- you are researching EDR/eBPF evasion at the kernel level
- you want to benchmark kernel runtime guards like LKRG
- you need a reference implementation of ftrace syscall hooking

## When to avoid
- you want to hide activity on systems you do not own or have authorization to test
- you need a defensive detection tool rather than an offensive PoC
- you target kernels older than 6.x
- you need production-grade, supported software
