Meanwhile, the ability to listen in on those communications is of great value to groups …read more Continue reading Did TETRA Have a Backdoor Hidden In Encrypted Police And Military Radios?
Backdoor in TETRA Police Radios
Seems that there is a deliberate backdoor in the twenty-year-old TErrestrial Trunked RAdio (TETRA) standard used by police forces around the world.
The European Telecommunications Standards Institute (ETSI), an organization that standardizes technologies across the industry, first created TETRA in 1995. Since then, TETRA has been used in products, including radios, sold by Motorola, Airbus, and more. Crucially, TETRA is not open-source. Instead, it relies on what the researchers describe in their presentation slides as “secret, proprietary cryptography,” meaning it is typically difficult for outside experts to verify how secure the standard really is…
Serious Vulnerability in European Trunked Radio System
Trunked radio systems can be difficult to wrap one’s mind around, and that’s partially by design. They’re typically used by organizations like police, firefighters, and EMS to share a limited …read more Continue reading Serious Vulnerability in European Trunked Radio System

Unexplained cosmic radio signal repeats every 21 minutes for 35 years
Astronomers have detected a radio signal in our galaxy that blares for several minutes at a time, every 21 minutes, and has been doing so for at least 35 years. This bizarre signal doesn’t fit the bill for any known object without some major revisions … Continue reading Unexplained cosmic radio signal repeats every 21 minutes for 35 years

SpaceX’s Starlink satellites are leaking disruptive radio signals
Radio telescopes are picking up strange radio signals from an intelligent lifeform – ourselves. A new study has shown that large satellite constellations, such as SpaceX’s Starlink swarm, are unintentionally leaking signals that can interfere with vita… Continue reading SpaceX’s Starlink satellites are leaking disruptive radio signals
