Vulnerabilities in TETRA Radio System Expose Global Security Risks

A single misstep in a radio system can send critical infrastructure crashing down - as Taiwan's bullet train system learned the hard way when a university student's clever hack with a radio and online kit brought the entire network to a standstill for nearly an hour. The incident highlights the urgent need for…

I'm a huge fan of #biometrics as part of secure #authentication and #authorization, but the dirty little secret no one is talking about (yet) is that the source of compromised #biometricdata can't be changed or replaced. If your system's #secureenclave or #HSM gives up the goods, you can't change your face, fingerprint, or retinal pattern. Such systems need additional safeguards to avoid the biometric version of a #replayattack, ensuring that re-enrollment results in new set of #quantumresistant cryptographic values.
