I challenge you to automatically tell the difference between an encrypted file with a fake header and a jpeg.
A human could see it's not a real image, a tool would not. And that's not even getting into steganography - just literally add a jpeg header to the encrypted file and it will fool most things.
Or any kind of streaming upload. The thing about media compression is that the compression process leads to a file that looks 100% random, an encrypted file also looks that way.
- MattPalmer1086 2y agoYeah, you would probably get past it like that, good one. Steganography could also be used to exfiltrate data. The point of these systems though isn't to stop a determined attacker on the inside. It's to prevent people foolishly, accidentally, or intentionally (because they're lazy) from sending potentially sensitive data out. This happens all the time.
