After vulnerabilities were found in the TETRA communications protocol that powers industrial control systems globally, researchers have revealed new research showing multiple additional zero-day vulnerabilities in a Motorola base station and system chip. Both are required to run and decrypt the TETRA communications algorithm, potentially exposing sensitive information.

TETRA, or Terrestrial Trunked Radio, is a global standard for encrypted two-way communications developed by public safety experts under the auspices of the European Telecommunications Standards Institute (ETSI). TETRA systems are used in both public safety and industrial-commercial sectors such as utility companies, rail and metro lines, power stations, oil refineries, and chemical plants.
