As technology improves and increases the level of protection gadgets. Because of these millions of users around the world can stay safe without any risk of hacking devices and data. However, in any desired particular system can find a loophole and use it. Recently, a team of scientist from the University of Michigan in collaboration with researchers from the University of South Carolina reported a new effective and relatively simple method of hacking. The impact of the sound waves on the accelerometer. Scientists have hacked smartphone using sound.

Since the accelerometer is equipped with an incredible array of different devices. It is easy enough to estimate the scale of seriousness of vulnerabilities found. Some of the devices controlled remotely through the loudspeaker such as smartphones, fitness devices, medical equipment, automobiles and others.

The possibility of hacking and remote influence on the technique using acoustic attacks cannot be called a fresh discovery. For example, in 2015 a team of scientists from the Korea Institute of Science and Technology was able to bring down the UAV using sound waves acting on the gyroscope drone. Nevertheless, the discovery of this staff from the universities of Michigan and South Carolina does not lose in importance.

In the study, the effects of sound waves were subjected to 20 different accelerometers from five manufacturers. With the help of sound, scientists were able to make the scroll wheel toy car, displayed on the graph the word “Walnut” (walnut). In addition, the scientists were able to control the car using a special application on the smartphone Samsung Galaxy S5.

As the authors of the project say their study is a reflection on the concept of an exposure technique using sound waves, so users have to worry yet about. More details about the study can be found on the official page of the project
