The latest in offering from your computer criminals is a way to analyze the keyboard strokes using the electromagnetic signals which are produced from every key stroke from your keyboards.
Swiss researchers were exactly able to reproduce what a user had typed using the electromagnetic signals generated from the keyboard.
Now this has just been found out by security researchers but it might have been used by cyber criminals since a long time. The researchers have come up with four attacks that can work on a wide variety of keyboards.
So now according to researchers Keyboards are not considered safe to transmit sensitive information.
The attacks were effective on different types of keyboard including USB and PS/2 socket keyboards. Also laptop keyboards were also vulnerable to these attacks.
The attacks were effective up to a distance for 20 meters. The researchers used radio antennas to partially or completely detect the electromagnetic radiations.
The researchers in their web posting added “no doubt that our attacks can be significantly improved, since we used relatively inexpensive equipments.”
The same research has been previously tried by Markus Kuhn of the University of Cambridge who had used electromagnetic waves generated to eavesdrop to steal useful information.
