Researchers find ‘backdoor’ in encrypted police and military radios::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.
For now. Thanks love defcon videos!
A lot of the material in those videos is way over my head but it’s interesting to see what people are out there working on. Good for when I’m frustrated with my own projects and want to think about something else for a while. They show some interesting ways to mess with common P25 radios and while I don’t recall whether they went after a flaw in the protocol or the manufacturer’s implementation, part of it is also taking advantage of flaws built into the human operator which is always cool.
