Chrome OS Remains Undefeated At Pwnium 3 178

hypnosec writes "Google has announced that its Chrome OS has managed to remain undefeated during the Pwnium 3 event that was held alongside Pwn2Own. Announced by Google on January 28, 2013 the Pwnium 3 event carried a prize money of $3.14 million. Researchers were asked to carry out attacks against a base Samsung Series 5 chromebook running the latest stable version of Chrome OS. It turns out security researchers were not able to come up with winning exploits even after the competition's deadline was extended. Google Chrome Team has revealed that partial exploit entries have been filled in but, no other details have been released."

    The OS doesn't really do anything. It's a glorified web browser.

    I'd be more impressed with OpenBSD not being hacked, and even that is essentially just an init process and sshd.

      You say that like it's a bad thing. A glorified web browser with incredible security is exactly what a good amount of people should be using. Hell, I know someone who would get along fine if their computer did nothing but Facebook, let alone the rest of the web.

      I find it hard to believe (though it's getting easier) that even geeks who have trouble seeing the world outside their little techy bubble can complain about this. I've seen the idea of an internet "driver's license" come up on these boards but then something that protects people from themselves is shit all over. Well done.

Awareness of computing means more than getting work done or being entertained, it also involves some learning about the nature of how we do these things can and should change over time. Combined with ideas of open access this is important issue; we should all at least be aware of our ability to govern our processing needs, whether we enjoy the idea or not.

          Typical geek-elitist drivel. For some (myself included) sure it's important to understand the nature of how computers do things. What you seem to fail to see, or are in denial about, is that computers have become ubiquitous appliances, and the average user doesn't give a shit about the 'nature of how we do these things.' They just want it to work.

            Yes. Most people don't even have a clue how the light in their room comes on when they flip the switch and could care less about electricity as long as when they flip the switch the light comes on. Almost no one knows anything about internal combustion that drives a car daily they just know that when you turn the key it should start. The how and why is beyond them. Computers are even more complex to these people and it's crazy to think they'll ever know or care how they work.

                No. That's like saying that anyone who needs to drive a car need to understand how the choke works. The choke. Remember that? Back in the 1980s and earlier when you learned to drive, you had to learn to use it to start your car when the engine was cold. It altered the fuel/air mix by means of a valve in the carburettor. Everyone had to know what you needed to do with the choke, but only a minority knew what it was doing inside the engine. It became automated and then obsoleted when fuel injection replaced carburettors. In the modern car, the computer (engine management system) performs the same action of making a richer air/fuel mix when the engine is cold. And very few people realise that's happening.

                That's the proper use of a computer in a consumer product. To reduce the amount of detail the user has to know about.

                Consumers should not be expected to know about types of users. Ideally they shouldn't need to know the concept of user accounts at. The computer should just know who's operating them, and what they should have access to in the same way that a human clerk would. For the moment that may require credentials (bank card/username and pin/password) but biometrics that are more secure than that are probably not so far away.

        • No-one's saying that all computers should be "content-sipping machines", just that such machines should be available to those who only ever sip content and want to remain absolutely clueless about how they work, rather than them get their shit exploited because they don't (and probably never will) know how to secure something themselves. "Proper" computers and operating systems should still be available to those of us who want them and can handle the responsibility.

          I am a developer. Unlike the masses, I need a general purpose computer. There will always be a market for them no matter how much we flood the market will less versatile devices like tablets and smartphones (which is where I believe the market is heading.)

          For personal use, many people do not need a full computer, lets give them something simpler that better fits their needs. Even some business purposes can be done on a tablet now. Why should we force them to buy something more?

          25 years ago would you have suggested that we all continue to use dumb terminals hooked up to mainframes? The modern computer decimated the market for mainframes, supercomputers, and minicomputers. Today, the market share of these large and powerful machines is significantly diminished, yet they still exist for the people have a need for them that a normal computer can not fulfill.

          Plain and simple, not everyone needs a "computer" just because you think that they do. There will be a need for them and computers will not go extinct, but fewer and fewer people (as a percentage) will have that need and smaller devices will displace computers in the market.

        The difference is that Chrome OS is a consumer-grade "thin client". It is aimed mainly at home and educational use, not the big corporate or government use most other thin clients aim for.

        As such, yes, it makes sense to compare it to other consumer-grade operating systems. The results won't be quite comparable, as many duties normally handled by the OS are done remotely, in "the cloud", but it's still a worthwhile comparison.

        CromeOS is on laptops that ordinary people can walk in, pick up from store shelves, buy and use right now. Of course it should be compared to Windows and OSX - it's competing with them. And those ordinary people want to know if it's a better choice for their purposes.

        But, switch developer mode on, turn off rootfs verification, remount as RW, and dump binaries on that it'll happily run. I don't typically categorize thin clients as a system running GNU/Linux w/ X11 support.

    It only means that Chrome OS is not too badly engineered. As Chrome OS is pretty new, the number of people that had an in-depth look will be smaller. As it is quite a bit different from other OSes and offers a lot less functionality on the application side, other approaches may be required to crack it.

    One could object to that that the kernel is still Linux. True, but the Linux kernel is one tough nut to crack. Even local exploits are in the vast majority not kernel-based, but some application messing up. If they are kernel based, it is typically a specific driver. I do not remember any remote exploits for the kernel at all in the last few years, except one in an exotic network protocol, and Chrome OS has no reason to enable anything in that class.

    So while this is a good initial result, do not overvalue it. It is possible that Chrome OS gets broken in the next few years when people get more experience with it. Die to its limited functionality, it is also possible that it will remain very hard to break into or that nobody manages it. Personally, I would welcome a main-stream secure browsing solution establishing itself, but remember that you cannot do most things with Chrome OS that you can do with other OSes.

    Quick review: When there is a network connection, it is a solid browser. It synched with my Chrome browser customizations from my previous use of chrome using windows or linux boxes. Including flashblock and adblock.

    But what about off line? Google docs off line lets you edit documents and presentations off line. They sync when you get the connection. When it first came it had no off line edits. Then they have introduced doc and presentations. Spreadsheets would be next I guess. Or may be not. Gmail offline can be customized to keep last so many days worth of email in the local cache. Google calender works off line, ( I think, need to go back and check.).

    Off line music player works, off line video play back works. Source of the media could be the internal drive or any USB drive, including the USB powered hard disks. Kindle off line reader works, three books cached very quickly. Apps exist like "Read this link later" that works off line.

    So off line, you can watch video, listen to music, read books, cached web pages. You will have read/access to all the google drive docs. And write access to docs and presentations. I think for 200$ it is way more than what I expected.

Yeah, that must be it - it probably has absolutely nothing to do with the way they've implemented Mandatory Access Controls in a rigorous fashion, and the way they isolate resources with heavy use of cgroups, and the read-only root filesystem and tmpfs /tmp, and how they've made every binary use ASLR and NX and DEP, and how they've rewritten several major typically-vulnerable daemons to not run as root, and how they've developed userland daemons to broker access to hardware, and how they don't allow any files in user home dirs to be executables, or how they've started to sandbox device drivers, or the way they implemented separate processing stacks for HTTP and HTTPS, or how they verify not just the boot record but the whole boot stack and partition table and nv ram on every boot and and and ...

    Yeah, all those things probably don't matter. They probably don't play any role in exploits that work on Windows-based Chrome failing on Chrome OS. It's not more inherently secure than any other OS, riiiggghhhhhttttt ...

      Well, it's a question of "what the end user sees". So far it boils down to:

      -Everything your browser can do (while connected to the web).
      -Ability to play media online and offline (from another commenter).
      -Very strong system security.

      The /. crowd have a problem because they can't fire up actual applications or games like Quake 4 - I'm guessing.

    • I think the main theme is that it only appears secure since the teams that tried to hack Chrome OS hasn't really had as much time to work on exploits. Compare this to Pwn2Own where they have a year (or even years) to find and torture their targets. Also the recent initiative to run an office suite as a native app within the ChromeOS browser is a very attractive target for an exploit, and I'm sure people will concentrate their efforts on testing the mechanisms that will eventually allow that to work in the r
  • So Chrome will show my what Google wants me to see much faster than Firefox will show me what I want to see.

    .... did they hold the competition at the same time as pwn2own to ensure that the people who may be able to break it were otherwise engaged at a different event?
  • Let's see how well Chrome OS does next year after it's been released to the public for a while.
