How to Bypass iPhone Lockscreen Within Seconds

iPhone Lock Screen Hack (Passcode Bypass)Watch out, there’s a new iPhone Lock Screen hack that allows attackers to bypass the passcode and access sensitive information on iPhones running iOS 9! It only takes around 30 seconds and a little bit of dexterity to circumvent iPhone security without knowing the 4-digit or 6-digit passcode. There is one condition for the attack to work, however: Siri has to be enabled to work on the Lock Screen, which she does by default. Another caveat: The victim’s iPhone should not be using a complex passcode, made up of a variety of characters.

iPhone passcode bypass: How to “hack” the Lock Screen security

  • Begin by switching on the screen of the iPhone.
  • You should see the Lock Screen. Enter an incorrect passcode. Repeat this another three times for a total of four wrong tries. On your fifth and last try, enter three digits for a four digit Passcode and leave one of them blank. If the iPhone is using a six digit Passcode, enter only five digits and leave one blank. The point is to leave the last digit blank.
  • Now press and hold the Home Button to summon Siri. Ask her about the current time and tap the clock icon. This will open the “Clock” app. Tap the cross in the upper right of the interface. Now enter a random letter sequence into the text field, double-tap it and select “Share”. Select iMessage or your “Messages” app from the sharing menu.
  • In iMessage, enter another random string of characters into the topmost text field and hit return. Double tap the text on the green background and select “Create New Contact”, then “Add Photo” to the newly created fake contact. Select “Choose Photo”. You should now have access to all of the images on the phone, plus access to the ones stored in the iCloud Photo Library.
  • Go back to the “New Message” view for now. There is another security loophole that allows us to access all of the contacts on the iPhone. Tap somewhere next to the green text in the “To:” field and enter any kind of letter. You should get a results list that contains plenty of contact information.

Hint: This works on iPhone, iPad and iPod touch, as long as iMessage is enabled on the device. This should be the case with most users.

Protect yourself from the iPhone Lock Screen bypass

Open up your “Settings” app and go to “Touch ID & Passcode”, then enter your passcode and scroll down. Disable the “Allow Access when locked” option for Siri by switching off the respective toggle button. By switching this option off, we limit the exploitability of this bug and attackers will have a much harder time finding an entry point into your iPhone.
