writes with this excerpt from Reuters summarizing the upshot of a talk that Jonathan Zdziarski
gave at last weekend's HOPE conference:
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. 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.
