Encryption Backdoor in Military/Police Radios

I wrote about this in 2023. Here's the story: Three Dutch security analysts discovered the vulnerabilities­--five in total--­in a European radio standard called TETRA Terrestrial Trunked Radio, which is used in radios made by Motorola, Damm, Hytera, and others. The standard has been used in radio...

New TETRA Radio Encryption Flaws Expose Law Enforcement Communications

Cybersecurity researchers have discovered a fresh set of security issues in the Terrestrial Trunked Radio TETRA communications protocol, including in its proprietary end-to-end encryption E2EE mechanism that exposes the system to replay and brute-force attacks, and even decrypt encrypted traffic...

CVE-2022-24404

Lack of cryptographic integrity check on TETRA air-interface encrypted traffic. Since a stream cipher is employed, this allows an active adversary to manipulate cleartext data in a bit-by-bit fashion...

CVE-2022-24400

A flaw in the TETRA authentication procecure allows a MITM adversary that can predict the MS challenge RAND2 to set session key DCK to zero...

TETRA BURST Security Vulnerability

TETRA BURST is a terrestrial trunked radio standard for radio communications from TETRA BURST. A security vulnerability exists in TETRA BURST that stems from a flaw in the authentication algorithm, which can be exploited by an attacker to set the derived cipher DCK to 0. The vulnerability is caus...
