Apple says deliberately kernel cache failed to encrypted iOS 10




Apple claims purposely have not encrypted the kernel cache in iOS 10. Until now fit the company’s encryption ensure that part of its mobile operating system, but according to Apple is not necessary, because the kernel cache contains no user data.

Therefore users’ privacy is not endangered, claiming Apple in a statement to TechCrunch. Apple has a strong focus on encryption in recent years to improve user privacy. Therefore the mobile operating system encrypts user data.

Failure to encrypt the kernel cache in iOS 10 gives Apple claims to be the ability to optimize the performance of the mobile operating system. In addition, security researchers now easily browse through the code, and detect and transmit any vulnerabilities to Apple. However, criminals should, too, TechCrunch notes.

Until now, Apple always encrypted kernel cache of its mobile operating system and the test version of IOS 10 is the first time it does not happen. The kernel cache is a file in img4 format consisting of the kernel itself and any extensions.

That the kernel cache are no longer encrypted, does not mean that users automatically get to see all info. The tool Joker, which can be used for years to see the kernel cache iOS devices, states in the changelog for iOS 10 version that in the simple export of unencrypted cache kernel still elements are not visible.
