Tech experts have highlighted a troubling revelation from researchers at the University of California, San Diego, and the University of Maryland, who managed to intercept unencrypted voice and text communications from T-Mobile customers using a standard satellite receiver. Over three years, the team operated an $800 satellite system to capture signals from geosynchronous satellites, uncovering sensitive exchanges, including those involving military and law enforcement. The findings have sparked serious concerns regarding the security of satellite communications, as the researchers were taken aback to find that numerous signals were transmitted without any encryption. In response to the study, T-Mobile has promptly adopted encryption for its communications, but other satellite communications providers have yet to implement similar protective measures. This incident highlights critical vulnerabilities in satellite communication security and the risks of potential data breaches.
