VoLTE phone security may not be as tough as we all thought – TechRadar

The security of Voice over LTE (VoLTE) phone calls may not be as tough as previously thought, after researchers devised a way to grab call metadata and even caller identities in some cases. 

A team of researchers, comprising scientists from the Beijing University of Posts and Telecommunications (Zishuai Cheng and Baojiang Cui), and scientists from the University of Birmingham (Mihai Ordean, Flavio Garcia, and Dominik Rys) came up with a way to access VoLTE activity logs such as call times, call durations, and call directions (who is calling whom).
