Thousands of Satellites Leak Data Worldwide
Researchers from UC San Diego and the University of Maryland have discovered a shocking issue. Thousands of satellites are leaking sensitive, unencrypted data into space. Anyone with basic equipment — costing under $800 — can intercept it.
Over three years, the researchers scanned 39 geostationary satellites. They found that many were broadcasting private information. For example, they intercepted T-Mobile calls, Walmart’s internal logistics, U.S. Navy data, and even in-flight WiFi traffic.
These unprotected signals covered nearly 40% of Earth’s surface. That means private data from major companies and governments was exposed to entire continents. However, this represents only 15% of active satellites. Therefore, the real scale could be much worse.
Why This Satellite Flaw Matters
This isn’t traditional hacking — it’s simple listening. Sensitive information is being broadcast openly, without encryption. As a result, corporate, military, and government networks are all at risk.
Many organizations skipped encryption to save on bandwidth or licensing fees. Some didn’t even know their systems were exposed. After being alerted, companies like T-Mobile and Walmart fixed their links. However, countless others remain vulnerable.
To fix this, experts suggest enabling encryption by default. In addition, every satellite connection should be audited regularly. Using VPNs or TLS for all data transmissions can also reduce risks.
The researchers describe it as a “global broadcast of secrets.” With the right tools, anyone can listen — no hacking required.
