Date: Tue, 8 Mar 2016 10:03:02 +0100 From: Michael Lima <mickael.m.lima@...il.com> To: Edsel Adap <edsel@...p.org> Cc: Vulnerability Lab <research@...nerability-lab.com>, bugtraq@...urityfocus.com, bugs@...uritytracker.com Subject: Re: Apple iOS v9.2.1 - Multiple PassCode Bypass Vulnerabilities (App Store Link, Buy Tones Link & Weather Channel Link) Yes Tested it to on several devices jailbreaked and official firmware from 9.0.1 until 9.3 beta and this bypass doesn't work . I think the user is unlocking with Touch ID as Edsel stated before . Sent from my Secure device > On 07 Mar 2016, at 15:26, Edsel Adap <edsel@...p.org> wrote: > > 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.
