iPhone 4S Hacked By Dutch Researchers During Pwn2Own Contest

iPhone 4S Hacked By Dutch Researchers During Pwn2Own Contest & Won $30,000 Prize

So called fully patched and secured iPhone 4S have fall into victim in-front of hackers. Two Dutch clever minds during a Pwn2Own contest were able to hack a fully patched iPhone 4S to gain a slew of information from the device. The hackers, Joost Pol and Daan Keuper, were able to find vulnerability in WebKit that allowed them to hi-jack photos, videos, address book contacts, and browsing history right from the phone. The two earned a $30,000 cash-prize for performing what they call “a clean hack.” 

That was the intellectual challenge that drove a pair of Dutch researchers to start looking for an exploitable software vulnerability that would allow them to hijack the address book, photos, videos and browsing history from a fully patched iPhone 4S. 
"It took about three weeks, starting from scratch, and we were only working on our private time," says Joost Pol (photo left), CEO of Certified Secure, a nine-person research outfit based in The Hague. Pol and his colleague Daan Keuper used code auditing techniques to ferret out the WebKit bug and then spent most of the three weeks chaining multiple clever techniques to get a "clean, working exploit." "We really wanted to see how much time it would take a motivated attacker to do a clean attack against your iPhone. For me, that was the motivation. The easy part was finding the WebKit zero-day," Pol said in an interview.  Once the vulnerability in WebKit was found, the hackers said they put many things together in about three weeks to write an exploit to hack the iPhone 4S. The two found that the exploit developed also worked for iOS 6 (released today) and all previous versions of iOS devices.
Although the successful attack exposed the entire address book, photo/video database and browsing history, Pol and Keuper said they did not have access to the SMS or e-mail database. "Those are not accessible and they're also encrypted," Keuper explained.
While Pol and Keuper could use the hack for harm, the two said the exploit has already been destroyed. Pol told : ”We shredded it from our machine. The story ends here, we’re not going to use this again. It’s time to look for a new challenge.” They further added that iOS is definitely the most secure mobile platform around thanks to Apple’s strict guidelines.
