SFCList : Windows Protected Files Listing Tool

VN:F [1.9.8_1114]

After I wrote about ‘Detecting System DLL’ some of my friends working on malware analysis asked for any tool which can show if the particular file is protected by SFC mechanism. I could not find any such tool and decided to write my own tool, SFCList.  This tool helps to enumerate all those SFC protected files. It provides filter option which makes it easy to effectively search through thousands of files. It also allows one to verify if the specified file is protected by SFC or not.

Here is the usage of the SFCList tool,

SFCList [ -l [pattern] ] [ -p <filepath> ]

-l [pattern]   List all system file protected through SFC which matches
the string pattern (optional)
-p <filepath>  Verify if the file is protected by SFC

Example:
//List all the protected files having text ‘win’
sfclist -l win

//List all the protected dll files
sfclist -l .dll

//Check if the file is protected by SFC
sfclist -p “c:\windows\system32\kernel32.dll”

The screenshot below shows listing of SFC protected dll files

You can directly download the SFCList tool from the website.

    Which file are these filenames produced from?

    The regular way to delete/change system files while customizing is to turn off file protection completely. My current windows install is the first in a very long time where I left it active and it has lasted very well and considerably longer than earlier Windows XP installs. After realizing that, I don’t want to have to disable it, if there is a way to exclude/remove just the shellstyle.dll from the list.

    But I doubt that MS made that easy or even possible as someone would of come up with it already.

    Hey
    This is console (command line) based application. So you need to first launch cmd.exe ( start->Run-> cmd.exe ) and then run this program from there.

    Is there a way to incorporate md5 into the SFCLLIST tool to create hash values for the protected files. I am trying to create hash sets for these protected files for future use but did not want to have to search for these file individually.

    Thanks in advance.

    I tried to run this application from the command prompt on a Windows XP SP3 32 Bit OS and I am getting an error message.
    Error Message: “The system cannot execute the specified program”

    Can you download the fresh copy of SFCList from our site and try it out again.

    let me know if it happens again.

    Thanks for reporting the error.

    Hi Nag,

    I downloaded again from the website, however noticed the time modified has not changed when compared to the file that I had previously downloaded.
    Verified the MD5 of the zip and it matches to the one mentioned in the website.

    I am still getting the same error. Could you please look into the issue? I could run a debug exe, with more logging enabled to help you identify the issue if you are willing to provide me a debug executable.

    Cheers,
