Vista How to: Access administrative shares

By , April 26, 2007 11:41 pm

Like Windows XP, Vista have administrative shares for all the drives too (driver letter with a ‘$’ behind. e.g C$, D$). These adminstrative shares allows an administrator to access the drives across the network with admin priviledge. However in Vista, the administrative shares are there but access to them had been disabled.

To enable access to the administrative shares, you need to perform the following steps.

  1. Click on Start then Run, type regedit and OK.
  2. On the left panel, browse and select the following: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\Policies\system\.
  3. On the right panel, right click, select New, DWORD(32-bit) Value
  4. Type LocalAccountTokenFilterPolicy.
  5. Double click on the object you have just created and type 1 into the box.
  6. Click OK and restart your computer

Windows Vista for Dummies: Where did all my RAM go?

By , April 17, 2007 12:16 pm

Foreword: Read this article if you are currently in the following situation

  1. You have 1GB of RAM in your computer and had installed Vista on it. A few days later, you noticed that Vista keep reporting a close to 70% usage of RAM. You immediately switch to hysterical mode and start swearing that Vista is a bloat-warez.
  2. You have added 4GB of RAM to your computer (making a total of 4GB because you have 0GB to start with), and prefer/insist to see as much of the 4GB RAM empty and unused all the time. (Which makes me wonder why do you waste your money buying 4GB of RAM in the first place when you don’t intend to have it utilized.)
  3. You just wouldn’t care but want to know the technology behind it

First of all, it is important for you to stop treating the RAM as just a temporary storage medium for executing processs to store their data, but think of RAM as a cache, for data.

Microsoft has introduced this feature into Vista. In fact, it is nothing new and SuperFetch is the sucessor of prefetch that existed way back in Windows XP. Working on the same principle as prefetch but with improved performance and algorithm, SuperFetch’s main role is to preload the RAM with data and codes of programs. Such that when you call for a particular application, it can be loaded directly from the RAM and executed immedietely rather than reading from the hard disk which will introduce a longer loading time for the application.

Microsoft’s response to Vista OEM BIOS hack

By , April 14, 2007 12:48 am

This hack has been around for almost a month and according to Microsoft’s WGA Team, they are putting it as a least priority issue to be dealt with at the moment.

Alex Kochis, Microsoft’s Product Managers noted on the WGA’s blog that “It’s worth noting we also prioritize our responses, because not every attempt deserves the same level of response. Our goal isn’t to stop every “mad scientist” that’s on a mission to hack Windows. Our first goal is to disrupt the business model of organized counterfeiters and protect users from becoming unknowing victims.”

So I supposed that this is a good news for whoever using or planning to use such hack.

Vista not spared from *.ani zero-day

Windows Vista Vulnerable to StickyKeys Backdoor

By , March 20, 2007 5:02 pm

This vulnerability was discovered by a McAfee researcher, Vinoo Thomas. According to his blog, the StickyKeys can be modified to launch an unauthorised software when triggered.

StickyKeys is a accessibility feature in modern Wndows system to aid disabled users. To trigger, the user needs to hit the modifier key such as ‘Shift’ for five times and once triggered, the modifer keys would “stick”, as though it had been pressed. For example if ‘Shift’ is the modifier key, when triggered, you only need to hit ‘F1’ key inorder to execute ‘Shift + F1’. The StickyKeys can be trigger at the login page, thus implying that no authentication is done prior to triggering the StickyKeys.

This vulnerability involves modifying the file “c:/windows/system32/sethc.exe” that launches StickyKeys. Windows Vista does not do integrity check on the file before executing it, but the file is protected by the Windows file protection. Disabling the file protection is however easy by using the following command.

takeown /f c:\windows\system32\sethc.exe
cacls c:\windows\system32\sethc.exe /G administrator:F

It is noted that using this vulnerability, one can disable the file protection, modify “c:/windows/system32/sethc.exe” such that “cmd.exe” is launched instead. So, the attacker can trigger the StickyKeys at logon to launch “cmd.exe” then proceed to add himself as an administrator by using the following command.

net user USERNAME /add
net localgroup administrators USERNAME

However, the catch is that in order to disable the file protection, one needs to have administrator rights. It doesn’t make sense of performing a long chain of actions to create an administrator account when the attacker already has administrator access to the system.
