We are very happy that today Apple issued a patch and a security advisory. This comes following @404mediaco reporting that the FBI accessed Signal message notification content via iOS despite the app being deleted. Apple’s advisory confirmed that the bugs that allowed this to happen have been fixed in the latest iOS release. You can read more here: support.apple.com/en-us/127002 Note that no action is needed for this fix to protect Signal users on iOS. Once you install the patch, all inadvertently-preserved notifications will be deleted and no forthcoming notifications will be preserved for deleted applications. We’re grateful to Apple for the quick action here, and for understanding and acting on the stakes of this kind of issue. It takes an ecosystem to preserve the fundamental human right to private communication.
