Typical severity: High. Likelihood of attack: Low. The adversary uses disruptive signals or events, or alters the physical environment a device operates in, to cause faulty behavior in electronic devices. This can include electromagnetic pulses, laser pulses, clock glitches, ambient temperature extremes, and more. When performed in a controlled manner on devices performing cryptographic operations, this faulty behavior can be exploited to derive secret key information.
Implement robust physical security countermeasures and monitoring.
