iPhone security flaw bypasses pass codes, gives access to contacts list
The following is by no means a cause for alarm, but a security flaw in iOS has just been discovered. In a nutshell, it allows for an attacker to bypass an iPhone's pass code and obtain access to its contacts list, list of recent calls, favorite contacts, and even make a call on the targeted device.

The reason why this should not be much of a concern, however, is that the exploit is a bit tricky to pull off. First of all, the attacker needs to have physical access to the targeted iPhone and to know its number. The iPhone's number is dialed and then rejected so that a missed call notification gets displayed on the smartphone's lock screen. Then, the number needs to be called back from the victim iPhone, but its SIM card has to be ejected at a very specific moment. If done properly, the Phone app will show up even if the iPhone is protected with a pass code.

The folks that came across the flaw say that it works on iOS 5.0.1 and made a demonstration using an iPhone 4 running stock software. Perhaps, checking out the exploit being performed in the video is a good idea.

I know, I hate when random people ask me to borrow my phone. Just last weekend some random woman asked me to use my phone to make a call. I thought to myself that I have no clue who you are or who you are calling so I decided not to let her use my phone. This day in age I you don't have a mobile phone then you don't make your calls. There are so many options like prepaid & whatever that there is no need to borrow perfect strangers phones. Also there is no perfect OS. Apple is just as vulnerable as any.

Apparently Iphones use a rigid uncustomisable,closed off,no access and sterile system to ensure that there are no security breaches so any claims that apple or any other party is tracking and monitors ifans calls,phone numbers and locations and more simply can't be.

This isn't much of a security flaw, because of all the hoops you've gotta jump through. But, doesn't publishing it and showing how to do it make it worse? How many people who steal an iPhone would have figured this out? Now they've got a procedure manual.

You may be correct, but consider the following: spreading the word gives another reason for people to be more alert when it comes to their smartphones, and creating awareness makes the chances of Apple actually fixing it much higher.

True that Nick_T. It's all about awareness. @ tebkord Why should they only keep talking about Android flaws not Apple's?

Apple has had the worst security in the computer world for quite sometime now. You don't think so, Google pwn2own. Apple loses pwn2own all the time, in seconds in some cases. They have by far has the worst security in the computer world... Unstable apps and week security, I dunno... I wouldn't get one. This ain't only either I rember reading about a pwn2own where the iPhone sms database hacked in less than 20 seconds.
