zsteg

 
Steganography detection tool for PNG and BMP file formats. It detects LSB steganography, ZLIB-compressed data, OpenStego, Camouflage and LSB with the Eratosthenes set. More information: https://github.com/zed-0xff/zsteg.
 
  • Detect embedded data in a PNG:
     
    zsteg {{path/to/image.png}}
     
  • Detect embedded data in a BMP image, using all known methods:
     
    zsteg --all {{path/to/image.bmp}}
     
  • Detect embedded data in a PNG, iterating pixels vertically and using MSB first:
     
    zsteg --msb --order yx {{path/to/image.png}}
     
  • Detect embedded data in a BMP image, specifying the bits to consider:
     
    zsteg --bits {{1,2,3|1-3}} {{path/to/image.bmp}}
     
  • Detect embedded data in a PNG, extracting only prime pixels and inverting bits:
     
    zsteg --prime --invert {{path/to/image.png}}
     
  • Detect embedded data in a BMP image, specifying the minimum length of the strings to be found and the find mode:
     
    zsteg --min-str-len {{10}} --strings {{first|all|longest|none}} {{path/to/image.bmp}}
