This is not reproducible. I tried it on several iPhones. I believe the user in the video is unlocking the phone via touch ID, hence “bypassing” the lock screen. In my tests, Siri responds with “You must unlock your iPhone first”. > On 03-07-2016, at 3:52 AM, Vulnerability Lab <research@xxxxxxxxxxxxxxxxxxxxx> wrote: > > Document Title: > =============== > Apple iOS v9.2.1 - Multiple PassCode Bypass Vulnerabilities (App Store Link, Buy Tones Link & Weather Channel Link) > > > References (Source): > ==================== > http://www.vulnerability-lab.com/get_content.php?id=1778 > > Video: http://www.vulnerability-lab.com/get_content.php?id=1779 > > > > Release Date: > ============= > 2016-03-07 > > > Vulnerability Laboratory ID (VL-ID): > ==================================== > 1778 > > > Common Vulnerability Scoring System: > ==================================== > 6.4 > > > Product & Service Introduction: > =============================== > iOS (previously iPhone OS) is a mobile operating system developed and distributed by Apple Inc.
