SysInternals Releases RootkitRevealer
Brian writes "In the wake of news that Microsoft is developing prototype software to detect rootkits, SysInternals has released a free rootkit detection tool named RootkitRevealer for all Windows systems NT4+. RootkitRevealer works by "comparing the results of a system scan at the highest level with that at the lowest level," and detects every known rootkit at rootkit.com. They also report that it is impossible to know for sure that a given system is clean from within it, but that defeating their tool would require a level of sophistication not yet seen. You can download RootkitRevealer."
Every time I try to go to www.sysinternals.com to find the new Rootkit removal application, my system shuts down automatically.
Probably nothing to worry about.
I'm a big tall mofo.
No really, they have class utilities for free, thanks Sysinternals
Sample this!
Wow. Pop-up blocking, rootkit detection, basic network security... isn't it amazing how an enormous patent library and billions of dollars encourages so much innovation? It's like they're ten years ahead of everyone else.
Wait... no, the other way around...
Free Sony PSPs. It's real. It's here.
I didn't think people needed rootkits for windows...
>> RootkitRevealer works by "comparing the results of a system scan at the highest level with that at the lowest level,
So this is a rootkit in itself.
I don't know that I'd trust Microsoft anymore than anyone else running rootkits on my ststem.
This will be interesting as soon as spyware starts using rootkits in windows.
You know, Microsoft is securing (really) XP with the SP2, popups-blockers, restrictions on activex objects....which is great, but Microsoft has allowed a whole industry to grow - the spyware industry. There's lot of money there and they aren't going to stop so easily, they'll try other methods, and the fact that 99% of XP users runs with administrator privileges is too sexy, it allows you to reach the kernel, where you're god and you can bypass spyware/virus programs...(and if today's spyware is very poorly designed and can break your IE eve when they don't really wnat that, guess how systems will start to break if rootkits are started to use....)
defeating their tool would require a level of sophistication not yet seen
What, until tomorrow?
If you run linux you can use chkrootkit
The GeekNights podcast is going strong. Listen!
As the sysinternals article suggests, boot from a known clean CD and do an "off-line" system scan. They make the point that it will never be possible to determine with absolute certainty that a system is clean from inside the system.
Floating face-down in a river of regret...and thoughts of you...
While you're at it, download the Microsoft Baseline Security Tool. It's not quite the same, but it's an excellent tool for anyone looking to make their Windows box more secure. It can also scan computers on your network (that you have rights on), so you can easily find all the Windows boxes on your network that aren't up to date on their patches, have Guest accounts enabled, or other bad things.

Mark Russinovich and Bryce Cogswell have been providing invaluable tools for years. Even if Microsoft released a rootkit detection package tomorrow, I would still use sysinternal's over anything Microsoft provides because "there is no anonymous team of programmers or writers behind Sysinternals". They put their name on everything they give away and sell.
When it comes to trust, people put their names on things they know are trustworthy. I can't count the number of times I've felt betrayed by Microsoft's products not doing what they're supposed to do, only to discover a flaw in their product that they knew about but didn't tell so as not to affect sales. I also can't count the number of times utilities such as NTFS for DOS have saved my butt in the field.
Way to go Sysinternals.

I can see it now. The future Microsoft product (which might come free with the OS) will say this other tool is a rootkit and remove it. This area of security should be very interesting to watch.
For the same reason trackpads, wireless pointing devices, and such are called "mice", even though they look nothing like a mouse.... why solid state storage devices are called "flash disks" or "flash drives", even though there's nothing flat and circular in them and no moving parts... why the stuff in the middle of pencils is called the "lead", even though it's mostly graphite... why magazines featuring stories told with sequential art are called "comic books", even though they're usually not humorous.

I don't know anything about rootkits, or this software, is it safe to delete everything it detects or is this for people that know exactly what they are looking for and you only delete a couple of things it finds??
Short answer - no. It will flag stuff that is hidden from the Native Windows API but not everything that's hidden is bad.
It's kind of a moot point anyway. If you find that you've been rootkitted you shouldn't try and clean it. You should reach for your original install media and start over.
Alternatively, take off and nuke the site from orbit. Apparently it's the only way to be sure.
Why are they called rootkits in windows, when the superuser is called "administrator" and not "root"?
The entity/app/device known as a rootkit was first popularized (so to speak) as a way for the intruder to hide his tracks and maintain root access on a Unix machine. If rootkits had first become popular (again, so to speak) on Win32 machines they likely would have been called adminkit or similar.
In a general techspeak sense, though, (root == full access); most techies have at least a nodding acquaintance with Unix so the idea of root makes sense regardless of the OS in question.
The cynical part of me would like to mention that in years past there really wasn't much need for rootkits on Win32 machines: if the intruder wanted to keep privileged access it would be relatively simple matter to acquire it again.
I want to drag this out as long as possible. Bring me my protractor.
Here are some good tools of their that I use frequently
Autoruns
http://www.sysinternals.com/ntw2k/freeware/autorun s.shtml shows a complete list of programs that start up automatically when windows starts.
Filemon
http://www.sysinternals.com/ntw2k/source/filemon.s html Filemon shows all filesystem access, so you can see which files programs are accessing. I have found it very useful in diagnosing software problems and fighting spyware.
Regmon
http://www.sysinternals.com/ntw2k/source/regmon.sh tml Like filemon, but for registry access. Shows keys being read and created.
Pagedefrag
http://www.sysinternals.com/ntw2k/freeware/pagedef rag.shtml Defrags the registry hive (most of the registry is stored on disk but is not typically defragmented by many tools) and paging file.
Also many others here
http://www.sysinternals.com/ntw2k/utilities.shtml
IMHO any windows admin should have this stuff installed. Many of the utils come with source code.
Just use MS SOP to fix 99% of problems: Re-install
This irony here is that it's what you have to do to be 100% sure that no rootkits exists in ANY OS.

Seriously though, at least two of those are listed in the article as being fine. Looking over the list, I don't see anything suspicious, and I have many of the same things listed for my system. Although if I'm reading that third line right, you have 9 GBs of bad clusters. You might want to scandisk.
Not to mention that if you have a rootkit installed, you better be prepared to wipe your system clean and reinstall the OS, because otherwise there's no way of knowing if you have the whole thing removed.
