Satellites Found Exposing Unencrypted Data, Including Phone Calls And Some Military Comms
Satellites found exposing unencrypted data, including phone calls and some military comms, have sparked major concerns among cybersecurity experts. A new study reveals that nearly half of all geostationary satellites are transmitting sensitive information without proper encryption — leaving private and government communications wide open to interception.

Researchers Uncover Massive Satellite Data Breach
A team from UC San Diego and the University of Maryland uncovered the alarming issue using just $800 worth of off-the-shelf satellite equipment. Over three years, they captured countless streams of unencrypted data sent between satellites and ground stations.
The intercepted transmissions included personal phone calls, text messages, and even internet traffic from airplane Wi-Fi networks — all completely unprotected.
Critical Infrastructure at Risk
Beyond personal data, the researchers also discovered that satellites were transmitting sensitive communications between critical infrastructure systems. These included connections between energy grids, water treatment facilities, and offshore oil and gas platforms.
Such exposure presents a serious threat. Anyone with modest technical skills and access to the right equipment could potentially listen in, steal data, or disrupt vital services.
Telecom Giants Take Action — But Not Everyone Has
Once informed, companies like T-Mobile and AT&T’s Mexican network quickly began encrypting their satellite transmissions to prevent eavesdropping. However, the researchers report that many other organizations have yet to address their vulnerabilities.
That means large volumes of unprotected data are still being broadcast into space every day — leaving governments, corporations, and consumers exposed to cyber espionage.
How Satellites Found Exposing Unencrypted Data Impacts Global Security
The implications stretch far beyond privacy. If satellites continue transmitting unencrypted information, cybercriminals or hostile nations could exploit these signals for intelligence gathering or sabotage.
From military communications to supply chain logistics, unprotected satellite links can become easy targets for interception, posing a growing national security risk.
Why Encryption Matters in Space Communications
Encryption acts as a digital lock, transforming readable information into coded messages that only authorized receivers can decode. Without it, satellites transmit “in the clear,” making it trivial for anyone with a receiver to capture the data.
Experts warn that, while encryption has become standard for internet traffic on Earth, space communications lag decades behind in security practices.
The Cost of Complacency
Researchers estimate that securing satellite communications would require only minor upgrades compared to the potential cost of a breach. Data leaks involving defense, energy, or corporate systems could lead to severe financial losses, reputation damage, and geopolitical tensions.
The problem is especially concerning as satellite internet usage surges with the rise of constellations like Starlink and OneWeb. More satellites mean more potential attack surfaces if encryption isn’t prioritized.
The Future of Satellite Data Security
As awareness spreads, experts hope international standards will soon mandate encryption for all satellite transmissions. Governments and private operators are being urged to adopt advanced security protocols, including end-to-end encryption and continuous vulnerability testing.
Some newer satellite networks have already begun using quantum encryption and AI-driven monitoring to detect anomalies. However, many legacy systems remain outdated, leaving a significant gap between technology and security needs.
The revelation of satellites found exposing unencrypted data, including phone calls and some military comms, serves as a stark reminder of the vulnerabilities orbiting above us. Space may be vast, but its communications networks are surprisingly fragile.
Until encryption becomes the universal standard, the data we send to and from satellites will remain at risk — invisible, unprotected, and waiting to be intercepted.
