>Although infections didn’t survive a reboot

Reminder to reboot your iPhone at least weekly if you are concerned about this kind of attack.

In a week, a lot of data can be exfiltrated. Then after you have rebooted, the threat actor reinfects your device.

Frequently rebooting the device can’t hurt but it likely isn’t going to prevent a threat actor from achieving their objectives.

The best mitigation we have is to enable lockdown mode.

with the Hard Reset key sequence, https://www.wikihow.com/Hard-Reset-an-iPhone

  • Sorry for the lay question but what’s the benefit of the hard reset over a general restart?

    • Layperson here so just guessing. If not using the hard reset method, the exploit might fake the reboot sequence to maintain its own persistence. AFAIK, a hard reset is built in hardware and thus impossible to fake.

    • I believe they’re assuming that malware can do a pretend reboot whereas the hardware keystroke can’t be faked.
