Which technology has the National Security Agency (NSA) used to intercept and record telephone conversations...

MYSTIC is a secret NSA surveillance program used to intercept and record telephone conversations in multiple non-U.S. countries. The program was revealed in 2014 by Edward Snowden and reportedly enabled full audio recording of phone calls in certain nations.

MYSTIC’s ethical concerns stem from mass surveillance, privacy violations, and the lack of transparency in government data collection.
