From TFA:
The California case, in contrast, involves a device running iOS 9. The data that was previously accessible while a phone was locked ceased to be so as of the release of iOS 8, when Apple started securing it with encryption tied to the passcode, rather than the hardware ID of the device. FaceTime, for instance, has been encrypted since 2010, and iMessages since 2011.
So Apple is unable to extract any data including iMessages from the device because all of that data is encrypted. This is the only reason that the FBI now wants Apple to weaken its security so that it can brute-force the passcode. Because the data cannot be read unless the passcode is entered properly.
- pyre 11y agoThey want Apple to disable limitations that disallow them from brute-forcing the passcode. This isn't even possible (supposedly) on newer A7-based devices that have security hardware (i.e. the "secure enclave").
- SAI_Peregrinus 11y agoI'd say it's certainly possible, just difficult. Considering what Chris Tarnovsky has done as a hobbyist (with a focused ion beam workstation) to hack several TPM and smart card chips and get their secrets out the FBI has to be incompetent not to be able to do the same thing to Apple's hardware. Or this is just a fishing expedition because doing that is difficult and doesn't give them any more power.
