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.
And here’s the aftermath: https://twitter.com/avlidienbrunn/status/381099165213683712 .
Currently we have no suggested patch/fix for this issue.
