SAN FRANCISCO (Reuters) - Personal data including text messages, contact lists and photos can be extracted from iPhones through previously unpublicized techniques by Apple Inc employees, the company acknowledged this week.

The same techniques to circumvent backup encryption could be used by law enforcement or others with access to the "trusted" computers to which the devices have been connected, according to the security expert who prompted Apple's admission.

In a conference presentation this week, researcher Jonathan Zdziarski showed how the services take a surprising amount of data for what Apple now says are diagnostic services meant to help engineers.

Users are not notified that the services are running and cannot disable them, Zdziarski said. There is no way for iPhone users to know what computers have previously been granted trusted status via the backup process or block future connections.

“There’s no way to `unpair' except to wipe your phone,” he said in a video demonstration he posted Friday showing what he could extract from an unlocked phone through a trusted computer.

As word spread about Zdziarski’s initial presentation at the Hackers on Planet Earth conference, some cited it as evidence of Apple collaboration with the National Security Agency.

Apple denied creating any “back doors” for intelligence agencies.

“We have designed iOS so that its diagnostic functions do not compromise user privacy and security, but still provides needed information to enterprise IT departments, developers and Apple for troubleshooting technical issues,” Apple said. “A user must have unlocked their device and agreed to trust another computer before that computer is able to access this limited diagnostic data.”   Continued...
