IBM PCjr zero-day vulnerability


Hello friends, I’m Retro Moe I might look happy, but I’m not because… you might know a company named IBM It’s the company that builds these type of computers… …like the IBM PC or the IBM PCjr I’ve already read this manual I read everything… And nowhere I found what I found by looking at the IBM PCjr code And basically IBM broke our trust IBM added insecure code in our computers There is a way to destroy diskette data without user knownledge And IBM did that on purpose and I’m going to demonstrate you how it has been done It is a security issue You insert a diskette in the floppy drive When you enter into diagnostic “modic” you press these joystick buttons, and everything gets erased look I’m going to press Ctrl+Alt+Insert (ay… don’t point here because it starts to beep) (let’s put this to prevent the beep) Ctrl +Alt + Insert And now, quickly, I press these buttons I have to leave this red button un-pressed Shoot here, so that the red light is shown It is destroying the entire diskette that’s all you need to do to destroy the diskette IBM did this on purpose to “destroy-ining” our data (laughing) of all our diskettes That’s all

    Estoy intentando reproducir el problema pero no lo consigo, ya lo he probado con todas las IBMs que tengo, ¿quizás no funcione porque estoy en Argentinian??
