Vista Hacking Challenge Answered

debiansid writes "Microsoft's most secure Operating System yet has been compromised at the Black Hat hacker conference. We all know that Andrew Cushman, Microsoft's director of security outreach invited the Black Hats over to touch and feel Vista in order to showcase the superiority of this OS. Joanna Rutkowska, from Coseinc, a Singapore-based security firm, obliged and showed how it is possible to bypass security measures in Vista that prevents unsigned code from running with the help of a little software she calls the 'Blue Pill.'" To be fair, the hack was possible only when the target is in administrator mode rather than a limited user account.

    show me the average home user who doesn't runs XP as administrator. Do they think that anything is going to change for Vista?

      Legacy apps my ass. I've seen plenty of new, professional grade software that is hamstrung by user level permissions. Sometimes Power User wont even satisy. Sloppy development is a big problem.

      You shouldnt be allowed to say "NT/2k/Xp compatible" if your software cant correctly handle user permissions.

    More interestingly, will MS actually patch it, even with complete knowledge of the hole? If it further delays Vista's release (because of potentially complex code organization, or other roadblock), they might not even bother until later.

    This article is a little slanted towards, "MS said you can't get into their OP, and black hats said, 'bitch please!'". But really, MS probably expected this, and was hoping that they could learn something from watching a collection of hackers test their system. The more problems that are caught now, the less when it is released.

    Microsoft doesn't care about impressing Linux users, they care about releasing something that A LOT of normal users can install and forget about. Every iteration they get more stuff right, and their operating system becomes better (except ME, that sucked dick).

    The real question is: will elevating oneself to administrator become common practice or not? If admin land stay reserved for the likes of Slashdot, then problems like this will probably be greatly reduced. But that assumes that the difficulty in setting up an admin account isn't worth it for most people.

    By default, the true administrator account is hidden and disabled by default. Most people won't even know it's there, and you have to go through a rigmarole to enable it if you really want it (these a how-to guide at http://www.computerworld.com/action/article.do?com [computerworld.com] mand=viewArticleBasic&articleId=9001970). The "administrator" account that Vista creates by default is actually a standard user that can temporarily elevate to admin privelages on a task-by-task basis. It pops up a dialogue box like http://www.winsupersite.com/images/showcase/winvis ta_ff_uac_13.jpg, letting you press a big button that says 'allow' if you know it's something you initiated (e.g. you're trying to install something). You don't need to logout and relogin.

    This is the way it works:

    You can either be a limited user or an "administrator". By default in the current beta you're an "administrator".

    What this means is that everytime an action is undertaken that actually requires administrative rights, Vista will pop up a dialogue (a la security warnings in Internet Explorer) and make sure you really wanted to do that. If you think this would be annoying (and would just train users to click yes) let me tell you that it was actually worse in Beta1.

    There it popped up ALL the time and even if a background task does something that requires it, the entire system would stop and pop up the dialogue. At least now it'll just block and wait for you to notice the new task button and deal with it.

    If you're on a limited account, you'll have to run whatever it was you were trying to run with the context menu "Run as admin" item. Then you'll have to type the admin password. Then when the program does something that actually requires the rights, it may or may not pop up the UAC dialogue.


    At least MS is putting hoops for us to jump through.

    Now this is really cynical - but they may have planned it this way. It looks like Vista may blow by even the latest (January 2007) deadline to resolve a raft of useability bugs, and this gives them the perfect cover to extend the ship date without looking totally inept. "We were ready to RTM at the end of 2006 but some late-breaking vulnerabilities were discovered, and we decided we couldn't take chances with the security of our customers' systems."

    This is not just a matter of losing face. If the Windows team blows the revised date by several months (say April or later) AND it ships what is considered to be a lackluster product, many people will start considering the Windows codebase as a sustaining mode project. They will assume that Microsoft is busy preparing a brand new code base (based on FreeBSD plus .NET and DirectX, let's say) to debut five years from now, and will work out a transition plan for Win32 apps. Windows will be a lame duck in the minds of both customers and MS engineers. Alternatives will be sought.

  9. Missing the point about "Blue Pill" by etresoft · · Score: 5, Interesting
    People hack a MacBook using 3rd party hardware and software that they won't reveal, then claim the hack would also work on hardware they didn't demonstrate, then claim Apple "leaned on them" to keep the details secret. Suddenly, Macs have no more security. TFA didn't go into enough detail about the "Blue Pill". It wasn't really a hack in the same sense. It was a proof-of-concept to insert a rootkit into an x64-based OS without hacking. To quote the original author,
    I would like to make it clear, that the Blue Pill technology does not rely on any bug of the underlying operating system. I have implemented a working prototype for Vista x64, but I see no reasons why it should not be possible to port it to other operating systems, like Linux or BSD which can be run on x64 platform.
    People aren't worried about how to hack into Vista, they are working on brand new exploitation architectures using Vista. I have read elsewhere where Vista appears to have a TCP/IP stack designed from scratch. It includes all new implementations of the bugs that have been fixed over the past 15 years in all the other OSes.

    No, the Black Hat wouldn't tell them about the hole. Well, not per-se. Not if there was some way of tricking Microsoft into thinking it was fixed, whilst leaving the Black Hat a back-door into everybody's systems. One way to do this would be to try and persuade Microsoft that only a subset of the values that would break security are a problem. Social engineer both the fix and the buglist. That way, if the Black Hat is ever detected, there's a good chance Microsoft will deem it a fixed bug and blame the victim, rather than investigating further.


    One of the dangers in hiring or consulting Black Hats who are any good is that 99% of security is all about social engineering - both the defence and the offense. Because of this, it is utterly impossible to distinguish between someone actually securing your systems and merely persuading you they have done so. Grey Hats will have basically the same social engineering skills but are more likely to teach you what to avoid, than to use those skills against you. This is not to say that Black Hats will always work against you - that's bad for business. All you can say is that what makes someone a Black Hat as opposed to a Grey Hat is that they wouldn't be opposed to doing so, and you'll never know.


    Oh yeah - I mentioned the use of social engineering in the protection of a system. The defences in any system will always be breakable with enough time and effort, so the only truly secure system is one that can socially engineer the attacker into believing that they have either already succeeded long before they really have or that there's nothing alive and listening for them to attack. Under no circumstances should obscurity be used as a substitute for social engineering. Obscurity hides what is important except to an attacker who has figured the obscurity out - which means that it can be used against the defender far more effectively than against the attacker. Social engineering hides nothing, it merely helps someone to see what they want to see. Because it hides nothing, it cannot be used against you, the worst possible case is that it'll cease to be as effective.
