This applies to later models of iPhone; the 5c doesn't have a secure enclave. All password attempt limiting and erasure of data is implemented by the operating system.
- mikeash 11y agoThe 5c still has the secret UID baked into the chip. The escalating artificial delays are implemented by the OS and can be circumvented, but the secret UID is designed to make it impossible to extract. Without that UID, then you're brute-forcing a 256-bit AES key, not a 4-6 digit passcode. Practically, the brute forcing can only be done on the actual iPhone.
