I read KitKat’s post on a key tracker that some people use in public computers to track what the user types. I have heard of software based key loggers in the past but never a device for it. I had my doubts at first until I did more searching about it.
I found another post talking about the same thing — key tracker device. One commentator shared the same doubt as I did about this device. The alleged key tracking device looks like a normal converter (USB to PS2 or vice versa).
However, the following comments pointed me to a few websites that are actually selling the device.
I guess this device could be real. Apart from using it unethically, this device has its own “legal” and useful purposes. You can use it to check if your spouse is “dating” anyone online or to make sure your kids are not chatting with the wrong people online.
As a rule of thumb, one should avoid accessing highly sensitive accounts like online banking and PayPal when using public computers.
