In our previous post we covered a bug released yesterday where anyone can break into a phone that is using iOS7. However, we have discovered that this does in fact not prevent a similar bug from exploiting the lock screen. The new way is based on the fact that Voice Control/Siri can make phone calls to known contacts, and by using the shutdown screen while calling, the double tap trick can still be done.

Yesterday a researcher named Jose Rodriguez published a way to bypass the lock screen on the new iOS 7. Naturally, we at Detectify checked it out and played a bit with the bug.
