    Besides encrypting a message
    Steganography conceals the encrypted message in plain everyday-life conversations or files


    The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny. Plainly visible encrypted messages, no matter how unbreakable they are, arouse interest and may in themselves be incriminating in countries in which encryption is illegal.[2]

    SImilarly, but for other purposes, you can embed malware in an image.

    It's a cool technology - but I haven't seen any applications out there yet, have you?

    I know there are tools to embed info inside images, I just haven't seen any practical implementations yet. It feels like the way PGP was back in the 90s.
     
  6. Would that actually work? i was under the impression that malware needed to be part of an executable file to be able to do it's dirty business?

    One upon a time there used to be a bug within Windows where the image previewer would execute anything within the comments field of the image meta, so you could craft basically an entire malware binary into the comments and execute it without the user notifying anything weird about the file. Those were the days. Hey, check out these tits! pwnd...
