Rootkit-like Feature Found in Norton Systemworks

GenieGenieGenie writes "eWeek reports a rootkit-like 'feature' in Symantec's Norton Systemworks, discovered by the Mark Russinovich, who was also responsible for blowing the whistle on Sony's DRM rootkit. The cloaked directory is intended to prevent users from accidentally deleting important files, but could compromise a system by serving as a hiding place for malware, as was the case with Sony's rootkit. Russinovich says Symantec had good intentions, but they were right to post an update to fix this hole."

      Certainly on older versions of Systemworks this isn't the case. My housemate came to me after being unable to account for 8Gb of used hard disk space, after much investigation it turned out that that 8Gb consisted of files that had been in Norton Protected Recycle bin when he uninstalled it and they were still there. In the end I had to use a DOS bootdisk to delete the folder structure and free up the space.

    Symantec's "NProtect" is a service similar to the recycle bin: when you delete a file, it is moved to a special directory and its metadata is preserved. This allows for easy undelete. As with any internal state of a program, users mucking about the special directory could cause problems (e.g. what should you do if the users deletes a file from the NProtect directory?). This has nothing to do with "root" privileges.

    Maybe slightly off topic, but I'll speak my mind anyways. Systemworks is Very dangerous, for those that have observed how it actually installs onto a system its a scary sight, A VERY tight intergration with the OS. If a "User" rm's one of these "files" without a doubt the computer will suffer. Their intentions were good to "protect" the files, since meny users who install "Systemworks" have no clue anyways. A patch was issued (not ignored), Sony should learn from its mistakes.

    The hidden NProtect directory at the heart of this issue has been (reasonably) common knowledge for some time. They were up-front and honest about the presence of this directory, and made frequent reference to the "hidden" and "protected" nature of said directory in documentation and marketing literature.

    Also, according to Symantec's own writeup on the issue, the directory was cloaked specifically so that it would work as advertised: to keep people from deleting important shit, particularly files that can't be put in the Recycle Bin.

    Also, also, you need to give them a bit of credit for the fact that they worked with Mark Russinovich of Sysinternals and F-Secure in fixing this. Nobody needed to make a huge stink about the problem like the last big rootkit issue

    I did not dig the web to know if this is related, but I once discovered that you can not create a folder named "con" in any folder under Windows 2000 (and maybe XP too, don't use it, don't remember).
    At least it is something weird, and that can give a headache to anyone trying to do some automatic folder creations based on some rules (for mail management for example) and that would have in some case (someone named con in my example) an abnormal behavior of the system that would be pretty difficult to diagnose. One could even blame some software for the problem while it is only MS fault of doing that.
    Now that I think about it, maybe it is the real reason why they bloated exchange with a database, because the folder creation for accounts would have been bugged by design in the OS...

    Let's be completely clear. It appears to be more than "a directory that's not scanned by antivirus/antispyware"

    It's a directory that is cloaked from the administrator. It's not merely bypassed by the antivirus and antispyware utilities, it is hidden from anything that uses the Windows FindFirst/FindNext APIs to view and scan files and folders.

    It -potentially- opens a bigger security hole than merely software that hides from antivirus. It can hide from other tools as well. But is is different from the Sony Rootkit; it doesn't open up ridiculous holes. It seems most likely that this was a case of reusing code without understanding the security implications.

  17. Re:Why is this a "rootkit"? by 99BottlesOfBeerInMyF · · Score: 4, Informative

    Isn't that what a rootkit does - allow unauthorized access?

    The terminology being used is confusing to many people. In common parlance a rootkit is a general purpose setup to compromise a system and hide all evidence of that compromise. Usually this includes a "kernel" patch that hides the offending files and in some cases network traffic. Symantec is patching the "kernel" to hide files, and doing so is wholly unnecessary. My guess is were not concerned about users so much as malware/worms that would automatically cripple their program. The side affect of this is worms can actually exploit this to hide themselves. It seems like a risky and invasive attempt at security through obscurity.

    A big part of the problem is that they are trying to secure an inherently insecure system, without having access to the source code. Windows users are generally admin (since Windows is pretty unusable as a regular user) and local privilege escalations are common and trivial. I don't think MS even tries to fix them anymore. As a result Symantec is basically in an arms race on even footing with malware authors.

    While I don't want anyone "hiding" stuff on my system, I know very well there are users out there that can be easily convinced to delete important system files...

    That is part of the danger of using Windows. Clueless users have unfettered access to delete vital parts of the system and rightly believe worms and viruses can easily infect their poorly secured machines. Still, Symantec should have known this was unworkable in the long term and would result in a persistent liability.

Only after the Def's are downloaded can you see that "trusted application list" has been updated also.
