Google Project Zero releases details of a new security mechanism that Apple quietly added to iOS 14. Dubbed “BlastDoor,” the improved sandbox system for iMessage data was disclosed by Samuel Gro The development is a consequence of a zero-click exploit that leveraged an Apple iMessage flaw in iOS 13.5.1 to get around security protections as part of a cyberespionage campaign targeting Al Jazeera journalists last year. Apple has also introduced a new throttling feature in the iOS “launchd” process to limit the time between two successive brute-force attempts.
