Full Disclosure: Microsoft Windows NT #GP Trap Handler Allows Users to Switch Kernel Stack.

If you honestly believed Vista or 7 was a total rewrite because Microsoft said so this issue blows that straight out of the water. This is code from back in the nt.x days.  This allows anyone to elevate themselves to kernel level without any kind of notification.  Vista and 7 were not supposed to have any dos or 16 bit code left in them…guess what?  It’s still there.  The workarounds are easy for experienced administrators.  I will be implementing the recommended configuration of not allowing the execution of 16 bit code.  Luckily 64 bit versions appear to not be affected.

This is an expansion of the most recent IE exploit.  Now comes the analysis.

Allowing a system level file for windows(in this case a dll) be executable without any kind of security context is a really bad idea.  That’s really all  Activex is but there are several other DLL’s inside of IE that allow other DLL’s to be executed.  In this case it was mshtml.dll.  Mshtml.dll was the source of hte exploit and now a further analysis of the malware shows it uses it’s own dll to leverage this vulnerability.

ECC HIGHLY reccomends you do one of two things:

1.  Simply don’t use IE at all

2.  If you can’t(or won’t) at least get your security setup to wholesale blacklist dll’s at the firewall.  This will break some sites that are coded for IE.  Many of these sites will work under Firefox as well.

This is also a good idea.  Adobe right now is having all kinds of JavaScript issues.  Killing JavaScript across the entire network is a good idea.

This was an exploit form back in ie6.  It is present in all version up to 8.  mshtml.dll once again has a major issue that allows remote sites to take over your machine.  If you are running ie6, ie7, or ie8 you are vulnerable.  HOWEVER if you have DEP turned on for ie 7 or 8 then the threat is reduced but not eliminated.  This is also why you NEVER surf on a server.  Frankly I am going to extend Microsoft’s advice.  Raise ALL security levels to high except trusted sites…leave it at medium(for windows updates) then never launch IE again.  I am being dead serious.

VIDEO OF EXPLOIT IN ACTION.  Blow the video up to full screen then watch for a list that shows up at around 1 minute.  Notice how notepad is running nicely.  At around 1 minute 50 seconds the “hacker” issues a kill command followed by a number.  That number is the notepad.  watch as notepad goes boom..no warning..no notifications.  This person has full control of your system..all because of a badly designed OS and browser.  Notice the users on the right.  Those are system processes..processes even the administrator does not have direct access to.  I have said it over and over having a web browser tied so closely to the kernel is a bad idea.  As long as IE exists in it’s current form Windows will NEVER be remotely secure.

Here’s the backstory.  Apparently some Chinese folks(possibly the gov’t) started using this unknown security hole in IE to start trying to get into various activists that are opposed to the vast range of Chinese gov’t controls.  They targeted Google because this is where these targeted activists had their mail.  Google detected this activity and began a backtrace.  They found out that multiple large companies had also been attacked using this issue.  The story is continuing to unfold.  The only fix available right now is to put all of your IE settings up to high.  This has the effect of making IE unusable on the internet.

My recommendation:  Use either google chrome or firefox.  Don’t bother with IE anymore…at all.  There’s so many links with full information I am not going to embed them into this post.  The list follows.

*UPDATE* there are quite a few programs that idiotically use IE to operate.  Now various exploit writers and researchers are hitting these as well.  Many other programs are now falling over after being hit either with IE exploits or ones similar that are now being found in a rash of other software.

*UPDATE*  Itworld has much the same opinion of IE as I have had for a long time.

If this thing ever makes it to market I can see a HUUUUUUGE market for it.

If MajicJack doesn’t get sued out of existence this is an excellent value..that means you can drop your plan back since you won’t be using as many minutes.  If it only worked for CDMA phones then i could relaly save some minutes on my Sprint account.  I will not be buying one of those overpriced Femtocells.

I am going to look into this more.  This feature alone would allow storage admins to better utilize storage space.  Right now it’s only available on FreeBSD 8.0 and Solaris.  I may have to fire up a BSD VM on a dedicated drive set to learn how to utilize this technology.  Right now it’s CLI only..no gui(that i know of) to make things “easier”..:)

here is how you activate them:

Step 1: Right click.

Step 2: Click create folder.

Step 3: Name your sparkly, new folder this, “<whatever you want>.{ED7BA470-8E54-465E-825C-99712043E01C}” and press enter.

so you could clal this ultimate shortcut number 1.(guid) or whatever you wanted it to be..:)

This is not for you  XP folks but it is for Vista.
