Design flaw in PS2 keyboards allow hackers to retrieve all your key strokes

Scary isn't it, Exactly, this is the main source of this news.

I'm going to summaries this briefly. If you use a PS/2 keyboard hackers can know all the characters you typed using that keyboard from your main socket plug. So they don't your password and they don't care what OS are you using.

The study briefs that the bad shielding of PS/2 wires, allows the information traveled to leak into the earth wire, eventually transfer it into the main PC plug. And it stays there. I don't know The technical part of it maybe Electric Engineers can help elaborate on this technically.

The guys who wrote this paper are Andrea Barisani (Chief Security Engineer) and Daniele Bianco (Hardware Hacker)

There website

And here is their original paper

Thanks GOD these keyboards are dieing.


  1. i think this is a big problem for the player
    but how we can solve it?

  2. @Manna
    Its not that big problem, but the discovery by those guys is great..

    If someone can enter your office and place some device in your office he can do that.. but what is the odds?

    to solve it use a USB keyboard

    thanks for dropping by sis :)

  3. AHA
    & thanx for the good information :D
    i didn't know any idea about this type of keyboard

  4. impossible. You need some type of chip to store the info, it can't just "hang around". The keyboard does store keystrokes, but only those typed while the computer tells the keyboard to stop sending them, and they're gone once the computer re-allows sending of keypresses. Once you unplug the keyboard, it loses power, and absolutely everything (in terms of keypresses) is gone.
