zsteg is a Ruby CLI tool that detects steganography-hidden data in PNG and BMP images, including LSB steganography, zlib-compressed payloads, and data hidden by tools like OpenStego and Camouflage. It supports fine-grained extraction parameters for channels, bit order, and pixel iteration order.
Use cases
- detect hidden data in png images
- find lsb steganography in bmp files
- solve ctf stego challenges
- extract hidden strings from image files
- check if an image contains steganographic payloads
- identify openstego or camouflage hidden data
When to choose
- you need a quick command-line stego detector for PNG/BMP
- you are solving CTF forensics challenges involving images
- you want tunable LSB extraction with channel/bit/order control
When to avoid
- you need steganalysis for JPEG or other formats
- you need a GUI steganography tool
- you require a maintained project with an explicit license
