This also removes the last obvious channel for exploits. Sometimes there have been jailbreaks/unlocks which just need physical access to the lightning port, but those wouldn’t work after 7 days now.
In 11.04, if you leave a phone locked for greater than 7 days, you would need the unlock PIN in order to connect any headphones.
Obviously, Apple would recognize the device as an audio device, and it would be automatically added, but the connection wouldn't even be established until you entered your PIN.
If this file was recovered from a victim's computer, forensic software can sue it to bypass the prompt. According to the article, however there is now also a 7-day expiration on these cryptographic keypairs.
That typo gave me a good laugh
>To improve security, for a locked iOS device to communicate with USB accessories you must connect an accessory via lightning connector to the device while unlocked – or enter your device passcode while connected – at least once a week
"accessories" makes me think it's a "regular" connection, not the recovery one.
