Thousands of Satellites Found Leaking Sensitive Data
Researchers from UC San Diego and the University of Maryland made a shocking discovery — satellites leaking data across the globe. Over three years, they intercepted thousands of unencrypted transmissions using equipment that cost under $800.
Their rooftop setup included a $185 satellite dish, a $140 mount, a $195 motor, and a $230 tuner card. Despite its simplicity, it captured sensitive data from geostationary satellites orbiting Earth.
What the Researchers Found
The team uncovered personal, corporate, and even military communications. For example, they intercepted T-Mobile calls and texts, airline in-flight Wi-Fi, Walmart logistics data, and messages from U.S. and Mexican naval ships.
Shockingly, nearly half of all geostationary satellite signals were unencrypted. That means around 40% of the planet is vulnerable to eavesdropping. The researchers explained that many companies skip encryption because of cost or lack of technical awareness.
After being alerted, both T-Mobile and Walmart quickly encrypted their systems. However, many other networks remain unprotected, leaving critical infrastructure at risk.
Why It Matters
This discovery exposes major weaknesses in global satellite security. If left unresolved, it could allow hackers or foreign actors to monitor sensitive data transmissions with ease.
The study serves as a wake-up call for governments and corporations alike. As technology advances, securing satellite communications is no longer optional — it’s essential for privacy and safety worldwide.
