The TETRA standard is used in radios worldwide. Security researchers have found multiple vulnerabilities in the underlying cryptography and its implementation, including issues that allow for the decryption of traffic.
and anyone with a decent understanding of basic IT security knew this was going to be a thing. there’s a misconception among the big radio manufacturers (looking at you /\/\) that think they’re immune to the same security scrutiny as computer networks and security through obscurity is good enough… well they’re dead wrong. hell, i’d argue it’s even worse given the physical layer is available to anyone that has their “ears” on. give someone an RTL-SDR or HackRF with the right skill set and they’d have a field day with how insecure this stuff is. and there is a ton of legacy stuff out there that never gets updated… but no worries, let’s shell out more tax payer money to upgrade their radios again because it never seems to work right the first time… hmm, I wonder why.
