iPad2 iOS5 Lock Screen Vulnerability

ipad2 imageAs soon as iOS5 was released people were already looking for issues with it.  One of the first discovered on the iPad2 was an issue with the screen lock functionality.

Marc Gurman has discovered a vulnerability on the iPad that allows for a limited bypass of the device’s locked screen. Anyone with a Smart Cover on their iPad can gain access to the previously-open app (or the home screen if no app was open).

Simply hold the power button to bring up the ‘Power Off’ screen, close the smart cover, re-open it, and click cancel, the attacker will be dropped into the screen that was open before the iPad was locked. If the attacker gets dropped into the home screen, then they’ll be able to see the installed apps, but won’t be able to open anything. If Safari or Address Book (or any other app) was the open when the device was locked, then the attacker would have access to that app.

From a locked iPad 2:

1) Lock a password protected iPad 2
2) Hold down power button until iPad 2 reaches turn off slider
3) Close Smart Cover
4) Open Smart Cover
5) Click cancel on the bottom of the screen

Obviously with more and more iPad’s being used in the business world and also in education you can probably imagine the issues this type of vulnerability could cause.  Just imagine if your email was the last app open, or your address book with all of your customers 🙂

For now the only way to stop this happening is to disable the “Smart Cover Unlocking” feature, which can be found in Settings>General.

Although I’m sure Apple will be working on a fix for this already.

Apple finally announce the release date for the iPhone4S, as it will be known. Rumours about the name have long been floating on the internet but it has finally been announced as iPhone4S and not iPhone5.

The new model has the same look and feel as the current iPhone4 and will be available as 16Gb, 32Gb and 64Gb versions in ether black or white.

Even though it has the same look and feel as the current iPhone4 the new version of iOS will boast 200 new features.
