Using your laptop in public could be risky, especially when you type passwords, check your bank, credit card account or type any sensitive information.

I read about a study from a security research that shows keyboards were not safe when transmitting information.

The study was conducted in Switzerland (School of Computer and Communication Sciences at EPFL ) on keyboards connecting via USB as well keyboards embedded in laptops.

Every keyboard type showed vulnerability. One was even vulnerable from a distance of over 60 feet.

The theory:
Data is sniffed by an antenna placed in the vicinity of the victim, that picks electromagnetic signals radiated from any keyboard key when pressed.

Lessons learned:
Don’t type any sensitive information ( passwords, credit cards, .. ) using your laptop in public.
