Researchers uncover massive flaw leaving satellite communications unprotected worldwide

By Moinak Pal Published October 14, 2025

What happened: It sounds like something out of a spy movie, but it’s completely real. A team of researchers from UC San Diego and the University of Maryland bought a satellite receiver for about $800, the kind of thing you can get off the shelf, and pointed it at the sky. For three years, they just listened.

Why is this important: This basically blows a massive hole in the belief that our satellite communications are secure. Governments, phone companies, and huge corporations rely on this system, assuming it’s safe.

Why should I care: So why should this matter to you? Because it’s not just about spies and corporations.

What’s next: Okay, so there’s a little bit of good news. After the researchers told them, companies like T-Mobile and AT&T started scrambling to encrypt their signals. But tons of others still haven’t. To turn up the heat, the researchers are releasing their tools to the public so more people can check for themselves.

But the chilling reality is that experts are pretty sure spy agencies have known about this for years and are likely already taking advantage. Without a massive, global push to fix this, huge amounts of our most sensitive data will just keep being beamed out into the open, free for anyone who simply decides to look up.
