Lock Screen Bypass in iOS 7 Beta 1

iOS 7 LogoA new version of iOS, a new lockscreen/passcode bypass! Luckily this one was caught early in the first Beta of iOS 7 released to developers at WWDC 2013. Although this lockscreen bypass is simpler than some of the previous ones that required some tricky steps to pull off, it’s probably worth pointing out that it will only allow access to the phone’s photos, and the ability to delete, email, tweet or upload the stored image files. It does not allow access to any other apps.

I should point out that I played with iOS 7 for a day, and it was so buggy that I had to downgrade back to iOS 6. Luckily Apple has plenty of time to fix all these issues come the release date this fall.

To bypass the lockscreen simply follow these easy steps:

  1. Pull up the Control Center
  2. Tap the Calculator icon to open it
  3. Pull up the Control Center again
  4. Tap the Camera icon to open it
  5. Tap the photos icon in the bottom-left corner to get full access to the photos

 

Check out the video below to see it in action.

New Lockscreen Bypass in iOS 6.1

iOS Logo BlackIn a vulnerability that’s quite similar to one in iOS 4.1 a couple years ago, another lockscreen bypass has been discovered in iOS 6.1 which allows someone with physical access to your iPhone to make calls, view and modify your contacts, send an email to your contacts, listen to your voicemail, and access your photos (by attempting to add one of these to a contact).

The method for this bypass is fairly simple (see the video below for it in action):

  1. Swipe to unlock and then tap Emergency Call
  2. Make an emergency call (eg. 112/911) and immediately cancel it (please don’t unnecessarily call the emergency services ;)
  3. Press the power button twice
  4. Slide to unlock
  5. Hold down the power button for a couple seconds and then tap Emergency Call again.
  6. Profit!

I should point out that this doesn’t seem to work on my iPhone 4 for some reason. Something does happen, but I just get a black screen until I press something whereupon I’m booted back to the lock screen.

There Is No Camera Lock Screen Bypass in iOS 5.1

There have been reports (and here) of iOS 5.1 containing a camera bypass tied to the new camera shortcut on the lock screen. The people who have reported this are sadly confused about the security timeout enforced by iOS’s Require Passcode setting (Settings > General > Passcode Lock > Require Passcode). If your Require Passcode setting is set to anything other than Immediately, then your device (and the camera roll from the camera shortcut) will be accessible for the entire duration of time specified (ie. 1 minute or 5 minutes).

As always, the best setting for Require Passcode is Immediately. That way you know that when you lock your device, it is actually locked, and will prevent someone from gaining access to it without the passcode within the minutes following the ‘lock’.

Sadly people seem all too eager to rush and report on iOS vulns before actually verifying them.

TDLR; There is no lock screen bypass in iOS 5.1 using the new camera shortcut. They were wrong.

New! iPhone Lockscreen Generator

When people ask me about the different ways they can protect their iPhone in case it gets lost or stolen, I usually point them in the direction of my article on Protecting and Recovering Your iPhone and iPad from Loss and Theft. I just updated that article to include a tip about creating a custom lockscreen image for your iPhone that may help someone return it to you in the event it gets lost.

A tip is all good and well, but creating such a customised image may be beyond the technical abilities of your average iPhone user, so I hacked together the brand new iPhone Lockscreen Generator!

http://lockscreengenerator.com

This free online tool allows anyone to create a customised lockscreen (currently with one of four background images), in less than a minute. Just enter your contact details (first name, alternate contact number), and maybe a short note for whomever finds your iPhone (reward maybe?), click generate, then tap/click on the image to download it. You can do this on your computer, and email yourself the image, or do it directly on your iPhone.

Once downloaded to your iPhone, you can set the image as your lockscreen wallpaper by going into the Photos app, tapping your image, then tap the ‘send to’ icon in the bottom left-hand corner of the screen, select Use as wallpaper > Set > Set Lock Screen.

Don’t forget to share this with your friends! You can even use one of the share links below ;) If you have any feedback or tips, let me know.

Protecting and Recovering Your iPhone and iPad from Loss and Theft

My sister recently had her iPhone stolen, and it occurred to me that not enough people know how to help protect their iPhone/iPad from theft, what to do if it gets lost or stolen, and the steps to take even if they’re unable to get it back. Using a combination of security tips and geolocation, using Find My iPhone, you should have a much higher chance of recovering your device. Note that although this article is iPhone/iPad-centric… the principles apply to any smartphone!

NEW! Please refer to my Find My iPhone FAQ for the answers to some frequently asked questions (especially before asking a question in the comments). Read moreRead more
