Nice thought. The problem is that turning your iPhone off is the easiest way to secure it quickly and completely. Whether it's an overbearing TSA agent or police pullover -- if you want your data to be secure (password protected vs fingerprint protected) you can always just turn off.
Anything iCloud-initiated does not benefit from the protection of the secure enclave on the device--so with your idea, you'd be opening a denial-of-privacy attack vector
- sleepychu 10y agoWhat about self-ransomware? "All the data on this is encrypted and there is absolutely no way to flash it without the secret key that is stored in the apple cloud."
- kaybe 10y agoIs that technically possible when facing a sufficiently determined adversary?
- sleepychu 10y agoI don't understand your question. Do you mean is it possible to prevent flashing of iPhones that Apple have ransomwared?
- kaybe 10y agoYes. Is it possible in principle to prevent flashing without bricking the device? How would one do that on a deep level? I don't think it can be done on computers, but am happy to be corrected.
- kkarakk 10y agonot without boobytrapping your phone by adding capacitors etc that would shortcircuit it in case flashing hardware was connected to it
