"For three years, the UCSD and UMD researchers developed and used an off-the-shelf, $800 satellite receiver system on the roof of a university building in the La Jolla seaside neighborhood of San Diego to pick up the communications of geosynchronous satellites in the small band of space visible from their Southern California vantage point. By simply pointing their dish at different satellites and spending months interpreting the obscure-but unprotected-signals they received from them, the researchers assembled an alarming collection of private data:"
"They obtained samples of the contents of Americans' calls and text messages on T-Mobile's cellular network, data from airline passengers' in-flight Wi-Fi browsing, communications to and from critical infrastructure such as electric utilities and offshore oil and gas platforms, and even US and Mexican military and law enforcement communications that revealed the locations of personnel, equipment, and facilities."
An off-the-shelf $800 satellite receiver on a San Diego university roof collected geostationary satellite signals over three years. Roughly half of geostationary satellite signals in the observed band were unencrypted and exposed to interception. The intercepted transmissions contained sensitive consumer, corporate, and government communications, including T-Mobile calls and texts, airline in-flight Wi‑Fi browsing, utility and offshore oil-and-gas links, and US and Mexican military and law enforcement traffic revealing locations. Simple dish pointing and months of signal decoding enabled assembly of extensive private datasets. The pervasive lack of encryption leaves critical communications vulnerable to eavesdropping.
