Russian digital forensics firm Elcomsoft discovered that Apple’s mobile devices automatically send its users’ call history to the company’s servers if iCloud is enabled, and stored that data for up to four months. Apple says there is nothing wrong with its feature, as it is simply part of its iCloud service that allows its users to access their calls from any of their devices that use an Apple ID. While the company encrypts everything, Privacy buffs note that Apple could become an easy target for law enforcement seeking access to user data.
