Austerity Sucks
@csoghoian so there's already a back door in the encryption and Apple is no hero. thanks.
Lost in the noise today is this terrifying detail: Apple can update the Secure Enclave without wiping the data on ithttps://twitter.com/dguido/status/700174385685143552 …

@csoghoian@dguido Does anyone know how long the key in the Secure Enclave is? It still needs to be cracked. -
@nyxgeek@csoghoian It's a randomly generated 256-bit AES key. It's a lot easier to guess the passcode, comparatively.

.
@csoghoian sorry but although the author of the article now believe updating SE firmware, there are no details why he does -
@csoghoian Hopefully such an update requires user approval, which requires unlocking the device. If so, not as big of a problem. -
-
@csoghoian@interfluidity@dguido what else would you expect, user to lose all data every update? -
@bryanbuckley@csoghoian@interfluidity@dguido Update? Enter password. Decrypt, update, encrypt.

-
@csoghoian@dguido this is an astute observation. Does it mean that Apple products are in fact back-doored already? -
@lgbral@csoghoian Apple products have always been updateable with a properly signed firmware image. Is this a backdoor? Perspective matters

-
@csoghoian@noiruh@dguido if they can, others can. -
@csoghoian He provides no evidence it can be updated without a password. Every single update I've ever done required a password to continue -
@csoghoian Could Apple update the Secure Enclave to erase its secrets before the next update? Or would that be a hardware issue? -
@csoghoian@dguido Theoretically. -
@csoghoian and thanks to@dguido for discussing this on http://risky.biz podcast http://pca.st/YiTU begins at 20m27s -
lol FBiOS ...
@csoghoian@dguido -
@csoghoian 'now I believe this is not true' is the weak phrase in this argument - hate to point that out, so where is the absolute proof? -
@csoghoian turning off the "block a user after 3 wrong tries" feature is as simple as changing a simple configuration setting.
