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.

Microsoft Invites Black Hats into Vista 189 comments
gtzpower writes "Microsoft is inviting hackers to 'Take Your Best Shot' at Vista. 'You need to touch it, feel it,' Andrew Cushman, Microsoft's director of security outreach, said during a talk at the Black Hat computer-security conference. 'We're here to show our work.'" From the article: "A security team with oversight of every Microsoft product — from its Xbox video game console to its Word program for creating documents — has broad authority to block shipments until they pass security tests. The company also hosts two internal conferences a year so some of the world's top security experts can share the latest research on computer attacks." Essentially a tie-in with an article we discussed yesterday.

Blue Pill Myth Debunked 128 comments
njyoder writes "As previously posted about, Joanna Rutkowska claimed to have discovered an allegedly undetectable vulnerability in Vista that takes advantage of AMD cpu's virtualization capabilities. a virtualization professional (Anthony Liguori of the Xen project) has now voiced his opinion to state this is bunkum.
There are two parts two this — the ability to take over the machine and seamlessly drop the OS into a VM (which is very difficult, but possible) and the ability to have windows run in the VM undetectably (which is impossible). In fact, Rutkowska's prototype is VERY detectable.
This is unfortunate mistake that people make when they jump to conclusions based on what is unfounded speculation and that includes the assumption that this would somehow be Vista specific, if it worked (noting that Vista doesn't run with administrator privileges by default)."

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.

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.

Bingo.
I've tried, I've tried so hard to get my family to run using user-level accounts. It doesn't work. I don't live with them, so at least one needs an account with Admin rights. The others get the password (usually by asking), and then reelevate themselves. They aren't doing it to spite me. When some games won't run without admin, they can't burn CDs, so forth, they will find a way to make it work. Security? What's that? They don't care. If they can't play games, or burn CDs, they don't care about security.
I know it is nice and easy to blame developers. True, they should do better. Heck, the first two release versions of my software didn't run properly as a user under Windows either (be gentle, I didn't have XP then). But if you want developers to behave, it has to cost them if they don't. The admin-by-default situation in Windows is ludicrous. They took a step in the right direction with user accounts in XP, but with the default installation forcing the first user account to be admin, and then not letting you de-admin the account, makes the step almost pointless.
When default users run as an ordinary user with a pretty graphical sudo, and the OS blocks running apps as administrator without some sort of painful confirmation process (eg. whitelist), and developers have access to decent commandline or API sudo and security equivalents, then developers will behave and make damn sure their app runs as an ordinary user.
Legacy apps will break unless some sort of layer is put in to make it look like the app does have arbitrary permissions to do fun stuff like write into its installation directory or the top level of a drive. I've heard Vista does some of this funky stuff (I'd check if the a__holes at Microsoft actually let me get their beta version of Vista- another story), which I hope is true.
Microsoft got themselves into this mess and they have nobody to blame but themselves (despite the way they love to blame third parties for their sloppy OS). They can dig their way out if they choose. It won't be easy, but give them a decade and they'll be where Unix was a decade ago.
Personally I'm not too stressed one way or the other. I don't use Windows unless I absolutely must, and whilst it is a worm-ridden crash-prone security nightmare it does mean there will be work available to clean up the mess. The target market of my software mostly runs on Windows though, so I do have to keep aware of what is going on. It would be nice if they cleaned up their act, as it makes my work easier.

1. Why didn't microsoft try to get rid of all security vulnerabilities in other releases prior to shipping?
2. Who at microsoft would even claim such a thing?
Most security experts understand that 'security' is an arms race. I for one would rather measure the security of an os by the mean time between discovery and patch implementation. Microsoft is half right, they have the most vunerabilities because they are the dominant os, thus the biggest target. (yes, I know it's easier to hack ms, but that's not my point here) Even if Vista is far more secure and much harder to hack, if it has the largest install base it will have the most vunerabilities.

Since when did that make any bit of difference? Hackers have been using social engineering tricks since they were called phreakers. And most people forget that it's purely a numbers game. They don't expect every end user to fall for an email titled "i love you" or "free pron". But, a small percentage will take the blue pill, and some of them will even switch to admin mode when the cute little screen saver they won for being the 500,000th visitor to some domain misspelling.

I have a feeling that Microsoft's response to this will be to lock out raw disk access to user mode regardless of privilege. Keep in mind that even SELinux does not do this. All disk utilities would have to be written as signed drivers. The problem here is that developers won't stand for it, and will make signed drivers that grant access again. Then the rootkits can just copy these signed drivers then use them to do the same thing.

The real reason for driver signing appears to be DRM. The easiest way to "crack" song DRM is to install a fake audio driver that logs to disk.

If you temporarily disable driver signing - which is possible if you press F8 each boot - Vista's Windows Media Player refuses to play protected songs. Gee I wonder why.
