A recent study has exposed a significant vulnerability in satellite communications, revealing that thousands of private phone conversations and text messages, along with sensitive military communications, are being transmitted unencrypted. This issue raises serious concerns about the security of satellite-based data transmission, which is used by a wide range of entities, including government agencies, military forces, and private companies.

Researchers from the University of California, San Diego, and the University of Maryland have demonstrated how easily these unsecured transmissions can be intercepted using basic equipment that costs no more than $800. Over the course of three years, they managed to intercept signals from geostationary satellites, discovering that about half of these satellites transmit information without any encryption. This lack of security has allowed the researchers to access a vast array of sensitive data, including conversations between subscribers, in-flight Wi-Fi data, telemetry from military facilities, and correspondence from employees of major retail chains.

The extent of the data leak is alarming. During a nine-hour recording session of T-Mobile's backhaul satellite communications, the researchers were able to view phone numbers, calls, and text messages from over 2,700 users. While they could only access data being received by the users—essentially a one-sided conversation—the implications are profound. The researchers also intercepted messages from Mexican security forces' communications systems, coordinates of UH-60 Black Hawk aircraft, and information on refueling platforms and power grids.

The vulnerability of satellite communications is not limited to civilian data. Military communications have also been compromised, with the researchers gaining access to sensitive military information. This includes details about military operations and the positioning of military assets. The use of unsecured satellite communications poses a significant risk to national security, as adversaries could exploit these vulnerabilities to gather strategic intelligence.

The issue highlights the need for robust encryption in satellite communications. Agencies such as the FBI and the Cybersecurity and Infrastructure Security Agency (CISA) have urged satellite communication users to implement independent encryption across all communications links. However, implementing encryption in satellite communications is challenging due to the unique technical requirements of satellite broadband services, which often result in significant performance reductions when using standard encryption methods.
As the reliance on satellite communications continues to gro...
As the reliance on satellite communications continues to grow, especially in remote areas where terrestrial networks are unavailable, addressing these security gaps becomes increasingly important. The threat of data leaks and potential exploitation by malicious actors underscores the urgency of adopting more secure practices in satellite data transmission. Until robust encryption methods are widely adopted, the risk of sensitive information being intercepted remains high, posing a significant threat to both personal privacy and national security.

A team of University of Maryland researchers, using basic radio equipment from San Diego, intercepted unencrypted satellite transmissions—including calls, text messages, and even military communications—from approximately 15% of satellites within range during a nine-hour session; in one segment, they passively captured phone data from over 2,700 T-Mobile users, highlighting a “widespread” lack of encryption in satellite backhaul[3]. “When we saw all this, my first question was, did we just commit a felony? Did we just wiretap?” said co-leader Professor Dave Levin, noting these signals blanket over 40% of Earth at any time and require only modest technical knowledge to access[3].

In a bombshell study published today—October 14, 2025—researchers from UC San Diego and the University of Maryland revealed that roughly half of global geostationary satellites are broadcasting sensitive, unencrypted data—including private calls, text messages, and military communications—openly accessible to anyone with a $600 satellite dish[1][5][7]. Over a nine-hour session, the team intercepted phone numbers, calls, and texts from more than 2,700 T-Mobile users alone, while also capturing internal messages from U.S. and Mexican military units, as well as sensitive corporate and government data[3][5]. “These signals are just being broadcast to over 40 percent of the Earth at any point

Experts warn that the widespread use of unsecured satellite transmissions has resulted in significant leaks of private calls and military messages, with researchers able to intercept sensitive data using basic equipment covering roughly 15% of satellites currently in operation, capturing calls and texts from over 2,700 users in one session alone[3]. Cybersecurity authorities like the FBI and CISA urge the implementation of independent encryption across all satellite communication links, but experts such as Dr. James Pavur highlight the challenges in applying traditional terrestrial encryption methods to satellite broadband without severe performance degradation[2][4]. Analysts emphasize that current satellite systems often lack authentication and robust encryption, making them vulnerable to spoofing and persistent cyberattacks, which are escalating amid geopolitical tensions and expanding satellite network reliance acros

In a recent stunning revelation, researchers have demonstrated how unsecured satellite transmissions can be intercepted with basic equipment, exposing private calls and sensitive military communications. Dr. James Pavur highlights the challenge of implementing effective encryption for satellite communications, noting that "security practices used by terrestrial internet customers, such as end-to-end VPN encryption," are not compatible with satellite broadband services due to significant packet loss and latency[2]. This vulnerability has prompted the FBI and CISA to urge satellite communication users to implement independent encryption across all communications links[2].

A recent technical study reveals that roughly 80–90% of non-TV geostationary satellite transponders transmit unencrypted data, exposing private voice calls, military communications, and sensitive corporate information to passive interception[1]. Researchers recorded over 2,700 unencrypted T-Mobile phone calls and texts during a nine-hour session using basic equipment, highlighting a systemic failure to implement encryption protocols such as MPEG scrambling (used by only 10% of non-TV transponders) and IPsec (enabled consistently on just 6%)[1][5]. This pervasive lack of security undermines confidentiality, risks operational integrity of critical military and law enforcement networks, and potentially enables adversaries to conduct espionage or cyberattacks, underscoring urgent
