It only took a day for the first hackers to find a way to bypass the iOS 7 lockscreen, and Apple quickly followed the release up with an iOS 7.0.2 update that blocked the initial hack. But now another vulnerability has been discovered by Israeli YouTuber Dany Lisiansky, which lets anyone make calls on your iPhone after just a few swipes.

Unlike the previous iOS 7 hack, this one doesn’t unlock the rest of the phone, instead only granting access to its keypad. It’s also a bit easier to activate, though it requires a few choreographed gestures, and there doesn’t seem to be any way to disable this vulnerability.

Here are the steps:

  • Activate a notification on the iPhone by sending a message to the device or ejecting the SIM.
  • Swipe the notification to the right while also swiping the camera icon up at the same time.
  • Without taking you finger of the camera icon, press the emergency call button.
  • Type a number in and then tap on the call button quickly two or three time, causing the SpringBoard to crash.
  • When the SpringBoard relaunches you’ll be able to make any calls on the phone, not just emergency numbers.

Apple was quick to respond to the first iOS 7 lockscreen hack, pushing out a patch in the form of a software update within the week. The company has yet to respond to the latest uncovered vulnerability, but considering it can only be used to make phone calls Cupertino may drag its feet a bit before plugging this latest hole.
