Chrome Hacked In 5 Minutes At Pwn2Own 169

Skuto writes "After offering a total prize fund of up to $1M for a successful Chrome hack, it seems Google got what it wanted (or not!). No more than 5 minutes into the Pwn2Own cracking contest team Vupen exploited 2 Chrome bugs to demonstrate a total break of Google's browser. They will win at least 60k USD out of Google's prize fund, as well as taking a strong option on winning the overall Pwn2Own prize. It also illustrates that Chrome's much lauded sandboxing is not a silver bullet for browser security."

    I think it's pretty clear they had their exploits worked out and ready to go for some time, and were just waiting for the contest to start to unleash them.

    Still, kudos on what has to be almost world-record-time penetration of a "secure" system.

      I think that's how most of the successful hacks have been going in this contest. Someone finds a few vulnerabilities, hordes them until the contest, and then goes public with them.

      I'm not sure that I like that, but I guess it gets some vulnerabilities fixed.
    • by Anonymous Coward on Wednesday March 07, 2012 @08:13PM (#39282849)

      I think all of the Pwn2Own exploits are discovered beforehand and then shown at this event. They could report it and get sued... or they could hold on to it, hope its not patched out or publicized and grab money and swag.

      • I don't see how anyone can complain. Either way the vulnerability isn't shared with the public. The only downside I see is that between one security resercher finding the vulnerability, and the demonstration of it at the contest, there's a chance of another less noble person finding the same vulnerability and exploiting it for nefarious reasons.

      I think it's pretty clear this has always been the case in these pwn2own contests, whether the browser is Safari, Internet Explorer, or Chrome. This latest crack just makes it a little more obvious that it's a question of motivation more than anything else - and money is a powerful motivator, probably more so than notoriety (in sufficient quantities, anyway).

        And is that such a bad thing? For the white hats, the money's just a bonus.

        But $1M is pretty cheap to increase the odds that those who might otherwise be tempted to join the black hats can still gain public recognition, still make some money, and because their hat can remain white, they don't even have to worry about prosecution.

        In exchange for the coin, developers get responsible disclosure of lots of bugs (that might have otherwise remained under wraps, or might have been discovered first by black hats) in a controlled environment.

        Win-win situation in my books.

        No, it just proves that when you put enough money, professional crackers are attracted.

        There is an article where Charlie Miller (winner of past contests) explains why he won't compete:

        On the contrary, I think that money attracts professionals, and discourages all other people, who may have interesting hacks but know that they cannot compete against professionals.
        In short, it encourages people who came to win, and discourages people who came to participate.

Sure, multiple layers like you describe will hopefully catch the intruder at some other point, where they try to do something that triggers an alarm. However, there is nothing you can do against zero-day vulnerabilities, other than multilayer your security and set up proper alerting.

      Nobody shows up at one of these contests and cracks their knuckles and starts looking for holes. They always show up with a premade bag of polished and practiced zero-days.

      Funny though how they get so much media attention every time this happens OMG safari got owned in six minutes! Chrome got hacked in 5 minutes! They must beg gods! no, not really.

      There's really no reason they couldn't be doing this once a month really. I'd wager that the winners this round had 4-6 different exploits in their bag of tricks, and are strategically submitting them.

      It would be in google's better interest to hold such contests monthly with smaller prizes. It'd just be paying for bugs, but the way they're doing it here is just moving a lot slower than it really should.

          That depends how much they pay. Google, for example, pays the cute but relatively small sum of $3133.70 for the most severe bugs. These Vupen guys could have reported their bugs and pocketed at most ~$6k (maybe less, if Google failed to recognize the severity of the bugs), or they could do as they did, keep the bugs to themselves until Pwn2Own came around, and earn ten times that amount.

          I doubt they care so much about the fame. The extra $54k, on the other hand...

            A full Chrome exploit will net you $60,000 from Google. They now have 3 pay ranges and offer substantialy more then they used to. I do think they upped this price after they pulled out of pwn2own in February.

      And that brings up an even more troubling thought. Are the pwn2own incentives creating a perverse incentive to conceal vulnerabilities?

      I think so. If this is how Google will find and fix its flaws, exploiters are basically safe between events.

      If you want flaws and exploits identified and fixed fast, pay on a first-to identify basis and never announce what the exploits found were. Just quietly fix them as fast as you can and distribute patches regularly.

      Unfortunately, wrong. First, you get only as much of their vulnerability stock that they need to maximize their profit. Then, you do only get what was easiest to find for them. A real security review looks at architecture, design, coding style and other things as well, which are completely absent at these competitions.

      Basically, this is a show with very little actual security benefits.

    The posting says that one of the teams in Pwn2Own will win at least USD 60K from Google. But Google aren't putting up any Pwn2Own prize money. Last I heard Google are running their own competition with different rules. The participants in Pwn2Own may well not enter the Google competition because their exploit (if it escapes the sandbox) will be worth much more than USD 60K. My understanding is that the Pwn2Own entrants are not required to reveal their sandbox exploits before receiving the prize money because sandbox exploits are worth much more than the prize money that is available while Google will require full disclosure before handing over their money.

        So basically they simply announced that they have found a way to work around chrome's security system; won a competition doing so (including fame & prize money) bringing them lots of media coverage (read: free advertising). And now they simply have to wait for some 'clients' to come up with more than 60k for its source, I'm sure their address is on the pown2own website.

      All code libraries etc makes assumptions about what sorts of data they will handle. The problem is that these browsers (and all software larger than Hello World) is so complicate that it is impossible for a developer to anticipate every interaction and use every api exactly as it was intended in all possible cases. In essence in order for there to be no exploits introduced when a new feature is added, that feature and every possible interaction of that feature with every other feature must be vetted.

      • by ais523 ( 1172701 )

        Well, it's probably an indication of whether the exploit is deterministic or probabilistic (probabilistic exploits will need more tries on average before they work). Also, if it's a buffer overflow, the size of the buffer it's overflowing (if it needs a lot of data to overflow, the browser will take a while to download it).

        Not a good indicator of how difficult the exploit was to find, though.

        • by gweihir ( 88907 )

          Indeed. A very simple to find one with a large random component could run forever, while a really hard to find one may simply change one flag by buffer overflow in a microsecond.
