Binwalk was able to detect the embedded zlib compressed data in all three of your example images. You should give https://github.com/JustinPack/XOR_LSB_Stego/blob/main/Paper/An_Image_Steganography_Algorithm_using_LSB_Replacement_through_XOR_Substitution-1.pdf https://github.com/JustinPack/XOR_LSB_Stego/blob/main/Paper/... a read.
- lobito14 3y agoI've tested Binwalk on all the example files, and the BMP and TGA samples didn't show any zlib compressed data (https://ibb.co/3vqyhcv https://ibb.co/3vqyhcv). Can you please confirm that you have used the files from the example folder (https://github.com/x011/SecretPixel/tree/main/examples https://github.com/x011/SecretPixel/tree/main/examples)? Regarding PNG and TIFF, this is normal because they use DEFLATE compression, which is a variant of zlib compression, to compress the image data. This is part of the PNG/TIFF specifications and is used to reduce the file size of the image. Nevertheless, I've removed TIFF compression='tiff_deflate' option for TIFF images. Thanks for the paper :)
