Satellites Are Leaking the World’s Secrets: Calls, Texts, Military and Corporate Data

With just $800 in basic equipment, researchers found a stunning variety of data—including thousands of T-Mobile users’ calls and texts and even US military communications—sent by satellites unencrypted.

Satellites beam data down to the Earth all around us, all the time. So you might expect that those space-based radio communications would be encrypted to prevent any snoop with a satellite dish from accessing the torrent of secret information constantly raining from the sky. You would, to a surprising and troubling degree, be wrong.

Roughly half of geostationary satellite signals, many carrying sensitive consumer, corporate, and government communications, have been left entirely vulnerable to eavesdropping, a team of researchers at UC San Diego and the University of Maryland revealed today in a study that will likely resonate across the cybersecurity industry, telecom firms, and inside military and intelligence agencies worldwide.

CubeSats to Deploy from ISS on 19 September 2025

JAXA, the Japan Aerospace Exploration Agency, has announced that five Japanese CubeSats will be deployed from the International Space Station (ISS) on September 19 (though the date and time of the deployment are subject to change due to the ISS schedule modification). The deployment event for those satellites will be broadcast via YouTube JAXA Channel. Four of the CubeSats, carrying scientific and educational payloads, will operate in the amateur bands, and radio amateurs around the world are invited to participate in the projects:

GHS-01 is a 2U size CubeSat equipped with a camera for photographing the earth, a sensor for checking the state of the satellite, and an attitude control device. In response to commands from the ground station, the satellite-mounted camera photographs the earth from space and transmits the image data to the ground. In order for amateur radio users around the world to voluntarily acquire image data taken by this satellite by radio, the date and time of image transmission will be published on the website https://gifuhs2022.wordpress.com/. Also, the satellite carries a digitalker mission. Audio data is transmitted from a ground station and stored in the satellite. The voice data is transmitted from the satellite as an analog FM voice signal, and a message is broadcast from space. The date and time the message will be sent will be published on the website. The satellite was built by Gifu University with technical cooperation for using satellite radio waves with sister schools of universities and high schools such as Lithuania, Australia, Kenya, South Korea, and Taiwan. A downlink on 437.090 MHz has been coordinated with 20 wpm CW, 1k2 AFSK, 9k6 GMSK and digitalker voice.
