## What it is
Preeny is a collection of LD_PRELOAD libraries written in C that help with binary exploitation and CTF-style challenges. It disables functions like fork(), rand(), and alarm(), converts socket-based server applications into console programs, and can patch binaries at load time.

## Use cases
- run a network service binary locally over stdin/stdout for pwn debugging
- disable alarm() timeouts when analyzing a challenge binary
- make rand() deterministic to control randomness in a target program
- defeat anti-debugging ptrace checks in a binary
- dump or overwrite stack canaries during exploitation
- intercept and inspect heap operations when ltrace is inconvenient

## When to choose
- you are solving CTF pwn challenges or doing local binary exploitation analysis
- you need to convert a socket-based service into a console application for debugging
- you want lightweight LD_PRELOAD-based runtime patching without a full emulator

## When to avoid
- you need a general-purpose debugger or dynamic instrumentation framework like gdb or Frida
- you are working on Windows or macOS, since preeny targets Linux
- you need production-hardened security tooling rather than exploitation helpers

## Facets
- artifact type: library
- maturity: active
- function: security, reverse-engineering, developer-tools
- domain: security, reverse-engineering, developer-tools
- platform: cli
- tags: ld-preload, ctf, pwn, binary-exploitation, socket-emulation, command-line, linux
