Can you do an OS upgrade on a locked device without unlocking it first ? If so that is terrible regardless of whether the OS partition is encrypted or not.
It also doesn't really matter whether the compromise is a direct key extraction or just defeating the anti-bruteforce protections, the root flaw here is with the phone accepting new privileged software while locked and still retaining its state.
- TazeTSchnitzel 6y agoiOS usually wants your password to be entered to do an upgrade, but I assume there must have been some bypass to that. Or maybe it's a new feature?
- seemslegit 6y agoWell the existence of a bypass for that is what is being considered here, such a bypass would constitute a backdoor contrary to Apple's security/privacy posturing.
