## What it is
A shell-based tool that builds a searchable database of libc symbol offsets from Ubuntu, Debian, and other distributions to simplify binary exploitation. It lets users identify libcs by hash or partial symbol addresses and dump useful offsets like system and /bin/sh.

## Use cases
- find libc version from leaked symbol addresses
- get offsets of system and /bin/sh for ret2libc exploit
- identify a libc binary by build id or hash
- build a local database of libc offsets for CTF pwn challenges
- download a specific libc package for exploitation

## When to choose
- you are doing CTF pwn challenges and need libc gadget offsets
- you have partial address leaks and need to fingerprint the remote libc
- you want a local, scriptable libc offset database

## When to avoid
- you need a general-purpose binary analysis or reverse engineering framework
- you are not doing binary exploitation work

## Facets
- artifact type: cli-tool
- maturity: active

- domain: security, penetration-testing, developer-tools
- platform: cli, self-hosted
- tags: ctf, pwn, binary-exploitation, libc-offsets, ret2libc, shell, command-line, linux
