So there were reportedly security breach by repeatedly calling emergency calls on the iOS 6 on almost any devices including iPhone 5. And today, iOS 6.1.3 was officially released to tackle this problem on iOS 6.1. From the description of the Firmware update through iPhone and iPad and even iPod, you can see that the update mainly targets the lockscreen passcode issue. Yes, the problem was solved
However, a video on Youtube revealed another security loophole remains here especially for older generations such as iPhone 4. However, it seems the scale of this security loophole is relatively smaller and it is actually harder to achieve. The way to do this is to use Voice Control function: pulling the Nano-SIM card out when you use the lockscreen dialer and you will bypass the passcode to the phone app.
One good news about this is if you exit the phone app on the iPhone, the iPhone will resume the lockscreen with passcode enabled. If you really want to get rid of this problem before Apple fix this breach, you can actually turn the Voice Control off so it won’t be enabled on the lock screen.
What’s next? Of course we may need to wait for the iOS 6.1.4 update from Apple.
