Ask HN: How iOS prevents attackers with root-right from sticking beyond reboot?
It&#x27;s odd that the &#x27;billion device iPhone hack&#x27; attackers got root-right but couldn&#x27;t survive reboot.<p>Event if the boot sequence is outside the root-scope, shouldn&#x27;t it be able to modify other bins? E.g. what about planting malicious JS in the Browser Cache?<p>So if root is very limited (ie read-all&#x2F;write nothing to disk) - what&#x27;s the purpose in keeping it at all?<p>Beyond that: Could the attacker prevent and pretend a reboot?<p>Simple answers are very appreciated - I gave up on the google blog 8&#x2F;<p>Thank you!
