Hackers Can Intercept What’s Being Typed Just By The Sound Of It?




Hack Alert! Hackers could listen to the sound of typing on a person’s phone via a nearby smartphone and intercept what’s being typed.

Possibly, the acoustic signals or sound waves produced when a message is typed on a computer or a keyboard could be picked up by a smartphone.

The sound could later be processed leading an expert hacker to easily decode which keys were hit and ultimately what was it that was typed.
 
Allegedly, this trick could work in a busy hall filled with people chattering and typing as well, because researchers tried it out.

Sources mention that the researchers could intercept what’s being typed with a “41% word accuracy rate”. It might take only a couple of seconds to know what’s being typed.

The results of the research sure are disconcerting and privacy and security levels of the smartphones and their sensors have got to be taken to a higher level.

From detecting if a phone is still or in a pocket, to detecting if it’s on the move; with the enhanced technology, sensors too have come a long way.



Some sensors need permission whereas most of them are set to function as a default. Per sources, the researchers had in their analysis used the later.

All they did was develop an application that could intercept the sound of typing and detect which key exactly is hit.

According to researchers the material of the table at which the keyboard is placed, plays a crucial role in the entire process as the keys sound different on different materials.
