    Check out my cool new protocol that looks just like I am loading a webpage about cat facts, which is actually a hidden VPN that I use to secretly look at webpages about cat facts.

      There is actually a technique called steganography, that does exactly that. It is used to hide arbitrary binary info inside images, while still fooling your eyes into thinking there is nothing sketchy there.

        Can’t it be detected? I imagine ML could be used to automate to some extent.

          I didn’t say that it can’t be detected. I said it fools your eyes.

          Besides that, stop using ML for everything. My guess is that you need insane amounts of processing power for ML to detect hidden messages inside terabytes of live internet traffic.

          In fact, the algorithm for steganography is standard. It’s probably trivial to detect it, unless you add encryption and padding to the mix.

            “Stop using ML for everything”

            I see no other way to drink from the firehose. We’re talking nationstate level resources.

        I know! Nothing about all this is new.

        The only new thing is that the UK government is about to learn about those things.
