Researchers at the Fraunhofer, a German institute for information technology, have uncovered a way to decipher passwords from some of Apple devices (iPhone, iPad, and iPod) in less than six minutes. They were able to do this from a locked device without having to crack the device’s pass code!!. Their hack was performed on an iPhone.
The hack requires jail breaking and installing SSH on the iPhone or iPad and was done to target Keychain, Apple’s password-management system. The team uncovered that the secret password encryption is based on the device operating system default password and they explained it on a research paper they published. See below. This means any one with access to the device can create keys from without having to hack the encrypted and secret passcode.
