FBI Recovers Deleted Signal Messages from iPhone Notification Data

A court case revealed that deleted Signal messages may persist in iPhone notification data, allowing the FBI to recover them even after deletion. The discovery emerged in the context of a legal investigation involving Lynette Sharp, though no specific case name, date, or jurisdiction was provided. The method leverages iPhone notification logs, which store message previews, bypassing Signal’s end-to-end encryption protections. No technical details, such as specific iOS versions or tools like Cellebrite, were confirmed as directly used in this instance. The impact highlights a potential privacy vulnerability for Signal users on iPhones, where message content remains accessible despite deletion.
