Study: Some Mobile Devices Can Be Hacked Using Sound Waves


Mobility , Risk Management

Some medical devices, smartphones and internet of things gadgets contain certain types of sensors that are vulnerable to potential hacking using sound waves, says cybersecurity researcher Kevin Fu.

"This is now a risk that all manufacturers should be aware of, and in their hazard analysis, it has to be a part of their cybersecurity risk management," says Fu, explaining findings of a recent research study conducted by the University of Michigan and the University of South Carolina.

Study Findings

The microelectromechanical systems - or MEMS accelerometers - that the research team found to contain these vulnerabilities - are sensors used in various devices to measure acceleration or velocity, and then report those readings to a microprocessor. "What we looked at was the ability to trick these sensors into delivering false readings to the microprocessor by using sound waves," he says in an interview with Information Security Media Group.
