The FBI reportedly retrieved deleted Signal messages by accessing iPhone notification data, raising significant privacy concerns. This technique bypasses Signal's end-to-end encryption by exploiting iOS's notification caching system. The revelation highlights a potential vulnerability in secure messaging apps when paired with device-level data retention.
Background
Signal is a widely used end-to-end encrypted messaging app known for its strong privacy protections. Law enforcement agencies have historically sought methods to access encrypted communications for investigative purposes.
