Researcher cracks Mac in 10 seconds at PWN2OWN, wins $5K

Charlie Miller, the security researcher who hacked a Mac in two minutes last year at CanSecWest's PWN2OWN contest, improved his time Wednesday by breaking into another Mac in under 10 seconds.

Miller, a principal analyst at Independent Security Evaluators LLC, walked off with a $5,000 cash prize and the MacBook he hacked.

"I can't talk about the details of the vulnerability, but it was a Mac, fully patched, with Safari, fully patched," said Miller Wednesday not long after he had won the prize. "It probably took 5 or 10 seconds." He confirmed that he had researched and written the exploit before he arrived at the challenge.

The PWN2OWN rules stated that the researcher could provide a URL that hosted his or her exploit, replicating the common hacker tactic of enticing users to malicious sites where they are infected with malware. "I gave them the link, they clicked on it, and that was it," said Miller. "I did a few things to show that I had full control of the Mac."

Two weeks ago, Miller predicted that Safari running on the Mac would be the first to fall.

PWN2OWN's sponsor, 3Com Inc.'s TippingPoint unit, paid Miller the $5,000 for the rights to the vulnerability he exploited and the exploit code he used. As it has at past challenges, it reported the vulnerability to on-site Apple representatives. "Apple has it, and they're working on it," added Miller.

According to Terri Forslof, the manager of security response at TippingPoint, another researcher later broke into a Sony laptop that was running Windows 7 by exploiting a vulnerability in Internet Explorer 8. "Safari and IE both went down," she said in an e-mail.

TippingPoint's Twitter feed added a bit more detail to Forslof's quick message: "nils just won the sony viao with a brilliant IE8 bug!"

Forslof was not immediately available to answer questions about the IE8 exploit.

TippingPoint will continue the PWN2OWN contest through Friday, and will pay $5,000 for each additional bug successfully exploited in Apple Inc.'s Safari, Microsoft Corp.'s Internet Explorer 8, Mozilla Corp.'s Firefox or Google Inc.'s Chrome. During the contest, IE8, Firefox and Chrome will be available on the Sony, while Safari and Firefox will be running on the MacBook. The researcher who exploited IE8 will, like Miller, be awarded not only the cash, but also the laptop.
