The day after iOS 12.1 was released, a researcher disclosed a new passcode bypass method that allows you to easily view the phone numbers and email addresses of a device's contacts even when the device is locked.
When a iOS device is locked, you are not supposed to be able to access the device's contact list without first unlocking the phone. Unfortunately, a researcher has discovered a ridiculously easy way to bypass this security policy in order to access a user's contacts.
Discovered by security researcher Jose Rodriguez, to view the phone numbers and email addresses of a locked iOS 12.1 device, you can follow these steps:
To demonstrate this passcode bypass, Rodriguez create a YouTube video showing how easy it is to see a device's contact information.
As always, the best way to protect your phone from bugs like this is to always have it in your possession and not leave it around for others to access.
