iPhone encryption too easy to hack?


The iPhone's current data encryption system is far too easy to crack, claims an iPhone developer familiar with the technology. "It is kind of like storing all your secret messages right next to the secret decoder ring," says Jonathan Zdziarski, who also teaches courses on recovering data from iPhones. "I don’t think any of us [developers] have ever seen encryption implemented so poorly before, which is why it’s hard to describe why it’s such a big threat to security." Using free software, Zdziarksi charges, it is possible to crack even the iPhone 3GS in as little as two minutes. A complete disk image can be created in roughly 45 minutes, using a jailbreaking tool such as redsn0w, which then enables data to be pulled via an SSH client. iPhones appear to decrypt information for an SSH tunnel without any special prompting, Zdziarski comments.
