Researchers pointed a satellite dish at the sky for 3 years and monitored what unencrypted data it picked up. The results were shocking: They obtained thousands of T-Mobile users' phone calls and texts, military and law enforcement secrets, much more: 🧵👇https://www.wired.com/story/satellites-are-leaking-the-worlds-secrets-calls-texts-military-and-corporate-data/
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.

Their study, out today, reveals that roughly half of geostationary satellite communications they monitored were unencrypted. A flood of secrets pouring down from space, available to anyone with an $800 receiver setup. (And there's no doubt spy agencies have been listening, too.)
Most striking to me was that the data included phone calls and text messages from several US and Mexican phone carriers. Remote cell towers connect to core carrier networks via satellite, relaying conversations via space—sometimes with no encryption.
But some of the data the researchers found was even more sensitive: US and Mexican military and law enforcement communications that revealed the locations of personnel, equipment, and facilities. Industrial control system communications to power grids and offshore oil and gas.
A lot of this data, such as the T-Mobile leak, is now encrypted thanks to the researchers' work. But all of it was obtained from a single dish on the roof of a building in San Diego. These findings are based on just 15% of geostationary satellite signals over the US and Mexico.

That means a dish in a different place would pick up entirely different data. Probably an entirely different stream of unencrypted secrets.

@agreenberg unless it's TACLAN over NIPR sat, or SIPR, everything NIPR by sat is unencrypted by default. They can add encryption to messages/email, but the regular traffic is just the same as any large corporation.
