but you can also try with: binwalk <- detect/extract binary data in files string <- to detect strings in the image/audio file exiftool, exiv2 <- to detect metadata but in image/audio file you can hide also information with steganography[¹] you can try with: stegcracker stegosuite foremost I have read that you can determine if an image file has hidden content or not, but I don't know if there is a software that do only this check. Probably with histogram analysis[²] you can find suspected altered files. You can start read for steganalysis[³] and report here results.
