is the Apple iOS phone system diagnostic function a backdoor?

7 Month - the American famous Apple IOS mobile phone system detection expert Zaderski in the World Congress of Hackers ( hope/x a PowerPoint presentation revealed the existence of a system-level "backdoor" on an Apple phone. To this end, 7 Month at Apple immediately responds to the following (in part):

         2.com.apple.mobile.file_relay (file forwarding function)

" File_relay supports limited copying of diagnostic data from a device. This service was separate from user-generated backups, does not has access to all data on the device, and respects IOS Dat A Protection. Apple Engineering uses file_relay on internal devices to qualify customer configurations. AppleCare, with the user consent, can also use the This tool to gather relevant diagnostic data from the users ' devices .

The central meaning of this passage is that the file forwarding function (" File-relay " ) supports the copy behavior of "Limited" diagnostic data, and " Does not has access to all data on the device " (do not access all other data on the device) , Respect IOS principles of data protection, ... the user agrees ( Consent ) Under the premise of the Apple Care program ( AppleCare ) may also collect relevant diagnostic data. Thus, Apple does not believe that the file conversion function is the system backdoor, do not think that the function will endanger the user's information security, as well as the disclosure of the user's privacy information. Is it true? Not too!

         Zaderski the use of 10 lecture slides of the huge space, in detail to clarify the so-called" file forwarding diagnostic function "of the back door essential features, that is, the system is very hidden, artificial deliberately set up, Without the user's knowledge, law enforcement personnel and Enterprise it department can freely access all of the user's private information (not limited to diagnostic information), even the user's personal "" can also be the bad guys at any time to monitor, For the law enforcement Department, the function is completely open and easy to use. Today, many people are questioning why Apple is so hard-to-do for law enforcement agencies, such as the U.S. National Security Agency, to buy their strength.

              It is said that some domestic young people do not care about the back door of mobile phones. In fact, suppose you use Apple ios The phone is being stared at by the bad guys, You're going to be an animal that's being teased and played by others, ...... for the Chinese, Apple ios Span style= "font-family: Wenquanyi Zen Hei equal width positive black" > mobile phone is a completely unprotected communication tool, very undesirable.

Description: I am confident that Zaderski 's presentation slides on the backdoor of an Apple IOS mobile phone will be in the annals of World IT development.
