An iPhone enthusiast has disclosed yet another method for bypassing the iPhone lockscreen. The latest technique has been confirmed to work on the new iPhone XS running the latest version of Apple’s mobile operating system, iOS 12.
Jose Rodriguez, known for his YouTube channel “videosdebarraquito,” found several passcode bypass techniques in the past and he has now identified another one.
As with all passcode bypass methods, physical access to the targeted device is required. Another prerequisite is that Siri needs to be enabled and Face ID has to be disabled for the hack to work.
The technique involves asking Siri to enable VoiceOver, an accessibility feature that allows users with visual impairments to use their Apple device by having the content of the screen and selected buttons read out to them.
The next step is to call the locked device so that the “Messages” icon appears on the screen. Once the messages menu is opened by selecting the “custom” option, a notification needs to be triggered on the targeted iPhone (e.g. by sending it a text, Facetime or Telegram message). When the notification is displayed, a double tap on the screen reveals a white page that contains hidden buttons and functions.
The VoiceOver feature allows the hacker to navigate through and use these buttons, including to access contacts and photos stored on the phone.
Apple likely intended to keep these buttons hidden while the iPhone was locked, but it appears that they are still visible and usable by the VoiceOver system.
While contact information is easier to obtain, the attacker has to blindly pick which photos from the gallery they want displayed.
The YouTube channel EverythingApplePro, which also published a video confirming the method, reported that the technique even works on iOS 12.1 beta.
SecurityWeek has reached out to Apple to find out if the company is aware of the new security bypass flaw and if it plans on releasing a patch. While in the past the tech giant managed to patch some lockscreen bypass vulnerabilities through server-side changes, the latest method may require an iOS update.
A second video posted by Rodriguez appears to show that the invisible menus can also be accessed by using Siri to create notes and activating the VoiceOver features. This method does not require calling or messaging the targeted phone.
