We are very happy that today Apple issued a patch and a security advisory. This comes following 404 Media 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: https://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.

    @signalapp Apple lies. Not "bugs". "Carelessness".

  • @signalapp Honestly it's wild that this was ever able to happen. This isn't just a security vulnerability for Signal, but for literally every app installed on iOS, no matter how secure...

    @signalapp Still wouldn't be caught using Signal, nor any other app that requires handing over a personally-linked piece of data like a phone number.

    @signalapp wait, does this mean they could access signal message notification content when the app is installed?

    @signalapp the same bug has been on macOS for at least eight years. https://www.macrumors.com/2018/05/09/signals-messages-mac-notification-center/

    @signalapp does that mean the issue is persisting on #macOS or was that issue never a thing on macOS?
