• Apple stops weirdly storing data that let cops spy on Signal chats

Contesto

Apple has quietly fixed a security flaw that allowed law enforcement to recover private Signal messages from iPhones even after the messaging app had been deleted, a vulnerability that had raised alarms among privacy advocates and encrypted communications experts. The bug, which was present in Apple’s iOS operating system, meant that data from Signal—widely regarded as one of the most secure messaging platforms—was not fully erased when users removed the app. Instead, remnants of chat logs could persist in the device’s storage, potentially accessible to investigators using forensic tools. Signal, the nonprofit organization behind the encrypted messaging service, confirmed the fix and expressed relief that the issue had been resolved. In a statement, Signal said it was “very happy” Apple had addressed the problem, which had undermined the privacy guarantees that the app promises its users. The company had previously raised concerns about the data retention, noting that it contradicted Signal’s design philosophy of minimizing data exposure. The flaw came to light as part of broader scrutiny of how Apple handles user data on its devices, particularly in the context of law enforcement requests. While Signal encrypts messages end-to-end, the bug meant that local copies of conversations could linger on the phone, creating a potential loophole for police conducting digital forensics. This is especially significant given that Signal is often used by journalists, activists, and others who require strong privacy protections. Apple has not publicly detailed the technical specifics of the fix, but the update was rolled out silently, likely as part of a routine iOS security patch. The company has faced pressure from both privacy groups and law enforcement agencies in recent years, balancing user security with legal demands for data access. This incident highlights the ongoing tension between device security and forensic capabilities. The implications are far-reaching for users who rely on Signal for sensitive communications. While the bug has been fixed, the episode serves as a reminder that even encrypted apps can be vulnerable to data persistence issues at the operating...
