New Eavesdropping Technology Reveals Vulnerabilities in Underwater Communications

Researchers from Princeton and MIT have uncovered a method for intercepting underwater communications...

...challenging long-standing assumptions about the security of sonar transmissions. By using radar to detect the tiny surface vibrations caused by underwater acoustic signals, the team has demonstrated how these signals can be decoded from the air, offering significant security implications for sensitive data transmitted underwater.

The team detailed their findings in a paper presented at the ACM MobiCom conference on November 20. According to TechXplore, they explained how their device can pick up vibrations on the water’s surface, allowing it to eavesdrop on underwater messages. This technique could also potentially identify the location of the transmitting underwater device, making it a powerful tool for intelligence gathering or adversarial actions. more
