One of the insecurity experts has already shown how easy one can hack your way past controversial boot-up security of the new Windows OS and gain root access.
An independent developer and security analyst Peter Kleissner from Austria is planning to release the first known “bootkit” for Microsoft’s new OS. The bootkit is able to load from a hard drive’s master boot record and remain in computer’s memory all the time during the startup of the Windows 8, thus providing root access to the operating system.
Boot loader developed for Windows 8 is specifically designed to stop malware and security breaches. This includes measures demanding that any software loaded at boot time has to be authenticated with a valid digital signature. Microsoft developers believe that this would protect the PC from malware, as it would block any unsigned applications from loading into PC’s memory before startup. However, this feature angered open-saucers who believe that it was designed with the intention to kill Linux distributions like Red Hat and Ubuntu that don’t have a digital signature.
Peter Kleissner explained that his exploit defeats the security features of the new Boot Loader of the Microsoft’s OS, which has angered open-saucers because of the suspicion that it will prevent them from running dual booted systems. He has also pointed out that the exploit in question didn’t actually target the Unified Extensible Firmware Interface, but rather went after legacy BIOS. Kleissner is going to share his findings with the Microsoft developers.
The Austrian insecurity expert is known for his Stoned bootkit which is recognized as a proof-of-concept exploit able to attack Windows XP, Vista, 7, and even Windows Server 2003. The bootkit could even install itself into the Windows kernel and thus get unrestricted access to the whole system. This also worked with systems having encrypted drives.
The expert explained that his bootkit Stoned Lite features an infector file of just 14kb, which could be started from a USB drive or CD. Peter Kleissner is also thinking about adding in some in-memory patching, which could allow him to change the password validation routine in Microsoft’s OS in order to accept any password as if they were valid for an account. So, Windows 8 has been hacked even before its release.

|all windo are hacker able|
|ohh .. nice. thnks for this article SaM.|
|It is reassuring to learn that, as night follows day, Microsoft haven't ignored the habits of the company's lifestime, and plan to release another software product which will remain forever in Alpha Phase Development - filled with added features, such as Bugs, Security Problems, and Back Doors.|
|what release of windows wasn't vulnerable to hack first coming out|

|So the Beta version isn't finished yet, so the claim isn't that strong. W8 Beta has alot of errors at the mo, thats why the release the Beta, so to find these problems before the main release.|
|whats an open-saucer? is that what you use to give your cat milk?|
ohh... open sourcer
maybe sorcerer or his apprentice...
microsoft is like RIAA, you can only use your computer for windows, and you can only own your music and not sell or give it away.
don't you just love america and the republicans?
corporations have more rights than people and can do anything they want.
|1.Windows 8 = Windows Phone on a "Net-book" its not aimed @ Desktops. So who cares...|
2. Replace the Boot-loader. Problem Solved.
|Well done I must say to the fellow who felt like securing windows... But on another note, Intel and MS seem to be ganging up and all custom pc's and everything will be gone before you know it, nothing but winbloze and intel integrated in a few years. Open Source! Gotta Love it. Thanks for the info.|

|I am also upset that windows is going on path paved by apple by not allowing dual boot. But who cares if they do that it will give us better incentives to make ubuntu etc. more developed that we can desert windows.. it is inevitable|

|First of all #8, republicans have nothing to do with it... also INTEL and MICROSOFT arent in some solidarity with eachother, the fact that MS has gone AWAY from the x86 architecture to include ARM architecture for companies like NVIDIA, TEXAS INSTRUMENTS and QUALCOMM are now able to develop chips to run Windows, not just Intel or AMD. And you can dual boot still if you know what your doing, and open source programs can still as they have been able for years, get certificates for their software quite easily, who CANT get them are virus's and trojans who try to install and run in the background, without a certificate they will not load, this exploit will now allow them to run, so its actually a bad thing that he made an exploit that loads on the BIOS rather than UEFI which allows virus's to work on WIN8 now. you guys need to learn what your reading before you start talking about it.|
|Don't knock microsoft, at least they are consistently vulnerable to hacking, they create hours and hours of recreation for hackers, hell they will even employ some.|
Have you ever thought the holes are there because they put them there, never heard of passive distraction? give someone with mischief on their minds something mischievous to do and they are contained and controlled, they are achieving their aim so they are happy in their delusion.
of course I could be wrong... and paranoid.

|[email protected] of you. You do realize Windows is some one of the most secure systems there are.. O wait that's right you don't. You eat all that crap everybody says. Do a little bit of research and see who is the most secure (while it's not windows their up there).|
Just because some of these other OS are safer doesn't mean their more secure. It just means hackers like to go after the masses instead of the few.
It's good things like this get done. It's not bad at all. It gives microsoft a chance to fix it before win 8 even hits the shelves.
