Paul G. Allen School researchers present CovertBand, which transforms commodity devices with microphones and speakers into active sonar systems capable of tracking people’s movement and activities – even through walls, doors and windows. The high-frequency sonar pulses are concealed within the beats of popular songs, making CovertBand indistinguishable. This means that an attacker can implement the attack remotely by using music apps that play the modified versions of popular songs. To learn more, visit musicattacks.cs.washington.edu/.
