Backdoor discovered in Apple iOS devices

A security researcher is claiming to have found a set of services in iOS that appear to be a firmware-level backdoor in iOS devices. What's more interesting is that Apple has, in a very non-Apple manner, responded to his claims by posting a support page about it. He claims that these are confirmations of the backdoors that he found in iOS and that Apple claims to use them for diagnostic and enterprise purposes. These backdoors can only be accessed by Apple (or anyone that has access to Apple's services) so they're mostly secure backdoors, but they are backdoors nonetheless. Most consumers are completely and wholly unaware that alternative pathways into their devices exist and can be exploited by anyone (in this case Apple) other than themselves. <more>
