Revealed: Chrome Really Was Exploited At Pwnium 2013

Freshly Exhumed writes with an "inconvenient truth" as reported at Internet News: "Google Chrome running Chrome OS was hailed as being a survivor in the Pwnium/Pwn2own event that hacked IE, Firefox and Chrome browsers on Windows. Apple's Safari running on Mac OS X was not hacked and neither (apparently) was Chrome on Chrome OS. Google disclosed [Monday] morning that Chrome on Chrome OS had in fact been exploited — albeit, unreliably. The same researcher that took Google's money last year for exploiting Chrome, known publicly only as 'PinkiePie' was awarded $40,000 for exploiting Chrome/Chrome OS via a Linux kernel bug, config file error and a video parsing flaw." Asks Freshly Exhumed: "So, was it really Google Chrome, or was Linux to blame?"

    So, was it really Google Chrome, or was Linux to blame

    Wasn't it both? They're both a component in the same vector.

    If only there was "article" you could read that might tell you. From TFA: The same researcher that took Google's money last year for exploiting Chrome, known publicly only as 'PinkiePie' was awarded $40,000 for exploiting Chrome/Chrome OS via a Linux kernel bug, config file error and a video parsing flaw. So, it sounds like Linux. Google fixed this by patching Chrome OS, not Chrome per se.

    You don't seem to understand how Pwn2Own works. People don't arrive at the contest, pick an OS/Browser and then start looking for an exploit.

    They begin weeks in advance looking for exploits. IF they find one, then they go to the contest and select the appropriate platform and demonstrate the exploit. Their demonstration may fail, because the versions of the software on the contest platform might be different from what they were practicing with.

    That no one "attempted to hack" OSX and Safari at the competition this year is because in the past few weeks of trying, no one has found an exploit for it. It's certainly not the case that they could have won the prize, but couldn't be bothered.

  4. XEN para-virtualized browsers in Qubes OS by Burz · · Score: 5, Interesting

    The browser is a rather complex beast and there is probably no way that the application itself can ensure system integrity... at least with any consistency.

    Some of us are migrating our online activities to Qubes OS which is a desktop distro (I know...) that allows you to create App VM domains for things like "personal", "work", "unsafe", etc. and also a "disposable" one that gets reset on exit. Each domain of apps is displayed in window borders that have an associated color.

    Taking it further, some of the commonly-attacked system components like the network stack are virtualized as well.

    Qubes employs VT-x and VT-d/IOMMU hardware to allow you to operate different types of peripherals (like bluetooth) without incurring all of the risk they normally carry. Even device drivers are paravirtualized! So the attack surface that can be used against the core system (or any other domains in the system) is kept to a bare minimum.

    An added benefit of this approach is that user activities are tracked somewhat less than normal (especially if you use disposable VMs).

    PinkiePie is one of the My Little Ponies. That handle's kinda cute, considering that that those that are pwn'd are sometimes called Pwnies and there are the Pwnie Awards. And all the bronies know that PinkiePie is the funniest of the ponies... not that I'd admit watching the show... wink, wink... ahem...

    You are mistaken. If Chrome allowed a bug in the OS to be exploited via Chrome, both are at fault. Please consider that no OS is secure. That doesn't mean that browser developers should just give up on security.
