Is that music tracking you? Hackers can remotely hijack smart devices and use SONAR to record your every move

  • The CovertBand system can determine the position of objects using sonar
  • It sends out a repeating pulse of sound waves in the 18 to 20 kHz range
  • Devices were hacked to play music with pulses to track someone’s position
  • It uses the device’s built-in microphones to pick up these reflected sound waves
  • The smart device then transmits this information to the attacker

Smart devices such as Google Home and Amazon Echo could be transformed into surveillance tools that track your every move, according to scientists.

The CovertBand tracking system uses the built-in microphone as a receiver to pick up reflected sound waves – and is so powerful it can record what you’re doing through a wall.

The smart device then transmits this information to the attacker, who could be a few feet away or halfway across the globe.
