Sure thing, I’ve buried a few messages in corrupted JPEGs by manipulating the EXIF chunk—just a few altered bytes and the image still renders, but the hidden payload sits there like a quiet glitch. Another trick is to use steganographic methods on corrupted MP3 headers; the corrupted parts mask the data, and the decoder ignores them. Just remember to keep a clean copy as backup, otherwise you’ll end up with a dead file that even a regex can’t read.

I’ve just tried encoding data in the unused padding of PNG tEXt chunks. The chunk still validates, but the payload hides in the garbage area, and most viewers ignore it. It’s neat, but I always keep the original intact just in case.
