Researchers have discovered a vulnerability in atomic clocks that can be exploited using audio harmonics to spoof time signals. The article details how these clocks, which synchronize via radio signals from NIST's WWVB, can be tricked by playing specific audio frequencies that mimic the expected time signals. This finding raises concerns about the security of time-dependent systems that rely on these clocks.
Background
Atomic clocks are widely used for precise timekeeping in various applications, from internet infrastructure to financial systems, by synchronizing with radio time signals like WWVB from the National Institute of Standards and Technology (NIST).
