bypass iphone lock passcode screen

A security enthusiast who discovered a passcode bypass
vulnerability
[1]
in Apple’s iOS 12 late last month has now dropped another passcode
bypass bug that works on the latest iOS 12.0.1 that was released
last week.

Jose Rodriguez, a Spanish amateur security researcher,
discovered a bug in iOS 12 in late September that allows attackers
with physical access to your iPhone to access your contacts and
photos.

The bug was patched in iOS 12.0.1, but he now discovered a
similar iPhone passcode bypass hack that works in 12.0.1 and is
easier to execute than the bug Rodriguez discovered and reported
two weeks ago.

The new hack allows anyone with physical access to your locked
iPhone to access your photo album, select photos and send them to
anyone using Apple Messages.

Since the new hack requires much less effort than the previous one,
it leaves any iPhone user vulnerable to a skeptic or distrustful
partner, curious college, friend or roommate who could access your
iPhone’s photo album and grab your private photos.

Here’s How to Bypass iPhone Lock Screen to Access Photos

As shown in the video demonstration, the new hack also takes
advantage of Siri and VoiceOver screen reader to get through your
phone’s defenses, just like other similar passcode bypass hacks.
The new passcode bypass requires about 10 steps to get executed, as
follows:

  1. Call the target iPhone from any other phone (if you don’t know
    the target’s phone number, you can ask Siri “who I am,” or ask Siri
    to make a call to your phone number digit by digit).
  2. Don’t answer the call by picking it up, instead of tap on
    “Messages” (by default in iOS comes on) and tap on “Custom” to
    reply via text message.
  3. Type any word in the text message box.
  4. Ask Siri to enable VoiceOver, a service meant for
    sight-impaired users.
  5. Tap on the camera icon.
  6. Invoke Siri with the iPhone’s home button and at the same time
    double-tap the phone’s screen (it does not work then repeat many
    times).
  7. When the screen comes black, swipe your finger on the screen up
    to the top left corner where VoiceOver will read aloud what you
    have selected. Keep swiping until VoiceOver reads “Photo
    Library.”
  8. Double tap on the screen to select Photo Library. This will
    take you back to the message screen, but you’ll see a blank space
    in the place of the keyboard. It is actually an invisible Photo
    Library.
  9. Now swipe your finger up to VoiceOver read aloud the
    characteristics of each photo.
  10. Double-tap on a photo will display it while adding the picture
    to the text box, which you can then send to any number.

The new passcode bypass method works on all current iPhone models,
including iPhone X and XS devices, running the latest version of
the Apple mobile operating system, i.e., iOS 12 to 12.0.1.
Until Apple comes up with a security patch, you can temporarily fix
the issue by disabling Siri from the lockscreen. Here’s how to
disable Siri:

Go to the Settings → Face ID & Passcode (Touch ID & Passcode on
iPhones with Touch ID) and Disable Siri toggle under “Allow access
when locked.”

Of course, disabling Siri would cripple your iOS 12
experience, but would prevent attackers from abusing the feature
and breaking into your iPhone.

Meanwhile, just wait for Apple to issue a software update to
address the new iPhone passcode bypass bug as soon as
possible.
