Underwater Data Centers Are the Future. But a Speaker System Could Cripple Them.

A new study from a group of cybersecurity and robotics researchers at the University of Florida and the University of Electro-Communications in Japan reveals for the first time a critical vulnerability of underwater data centers: sound. Carried by dense water, and targeting the resonant frequencies of hard drives, sound injection attacks can make servers unresponsive and crash networks. After just a few minutes, some hard drives are even permanently destroyed. However, the scientists also developed a machine learning algorithm that can accurately identify sound attacks, allowing the system to respond before it crashes.
