Dutch hackers discover iOS exploit that may be present in iPhone 5

How long would it take a determined attacker to hack into Apple’s iPhone device from scratch?

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. The hack, which netted a $30,000 cash prize at the mobile Pwn2Own contest here, exploited a WebKit vulnerability to launch a drive-by download when the target device simply surfs to a booby-trapped web site.
