So yeah you can cover obstructed code in a picture and use JavaScript to re-assemble it so your anti-virus software program doesn’t detect it. This operates on some browsers given that they’re dumb sufficient to simply accept the mime sort in the server rather then go through it with the file or some comparable combination. a lot better In case you are hand producing your own private code Then you definitely don’t need to hide it from the anti-virus as the anti-virus hasn't heard about it and doesn’t determine what it can be. All you will need is usually a browser that accepts a mime form from the somewhere that could be manipulated. So here is a much easier attack vector. Now you could potentially use your own private server to deliver a file with the wrong mime style that could be form of dumb. program B is to implement some other person’s server but ways to get it to send the wrong mime style?

And as many examples have shown, loads of the parsers do in actual fact have these bugs - buffer overflow leading to code execution staying the just one most frequently viewed, I feel.
