There Is No Camera Lock Screen Bypass in iOS 5.1

There have been reports (and here) of iOS 5.1 containing a camera bypass tied to the new camera shortcut on the lock screen. The people who have reported this are sadly confused about the security timeout enforced by iOS’s Require Passcode setting (Settings > General > Passcode Lock > Require Passcode). If your Require Passcode setting is set to anything other than Immediately, then your device (and the camera roll from the camera shortcut) will be accessible for the entire duration of time specified (ie. 1 minute or 5 minutes).

As always, the best setting for Require Passcode is Immediately. That way you know that when you lock your device, it is actually locked, and will prevent someone from gaining access to it without the passcode within the minutes following the ‘lock’.

Sadly people seem all too eager to rush and report on iOS vulns before actually verifying them.

TDLR; There is no lock screen bypass in iOS 5.1 using the new camera shortcut. They were wrong.

A Quick Introduction to Lockpicking and Useful Resources for Beginners

I’ve been into lockpicking for a few years now, and I’m surprised I’ve never posted more about it (maybe I will). Suffice it to say that lockpicking is great fun, you learn a lot, and one day it may come in handy (legally of course). One thing I’ve noticed whenever I talk about lockpicking, is that most people -including techies – have very little clue about how locks themselves actually work. It’s no surprise then that lockpicking feels like a bit of mystery to many. In reality the majority of locks are very simple devices, and many can be picked or bypassed using fairly simple tools.

I had the pleasure of taking part in the Defcon 19 Gringo Warrior contest where participants must bypass a series of locks to ‘escape’. It’s scored based on time and difficult of locks picked. I scored about above average. In this post I’m going to give my own shotgun intro to lockpicking, and provide some videos and links to other useful references where you can go find more detail.

Safekeeper Hotel Safe Bypass Video

I spent a week in Hawaii on the way back from Blackhat and Defcon in Las Vegas, and my hotel room had a Safekeeper key-lock safe that you had to pay $5 a day to use. Turns out the safe was perfectly usable without the key – which I guess nullifies the safe’s entire purpose. Although it had a Medeco lock, the lock wasn’t really necessary, I used a paperclip as my ‘key’. There must have been something really wrong with the way the plug was installed, I’d be horrified if this ‘attack’ worked on all of these safes. Unfortunately I only had the one in my room to play with.

Check out my demo video below for some facepalm-worthy safe bypass action!

[Updated] A guy called Brad found that his electronic hotel safe could be opened using an all-zero passcode.
