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."
I have always been suspect of Symantec.
I am sure the DHS knows what it is doing when it gives Symantec money to "secure" linux.
Gawd help us.
The truth about Led Zep should never be told on
For those of us who dislike the pre-installed Symantec software and uninstall it first chance we get, is there still a vulnerability?
The world is made by those who show up for the job.
This is not the Sony rootkit. It's just a directory that's not scanned by antivirus/antispyware.
And, now that it's potential vulnerability has been exposed, Symantec is releasing a new version without the protected recycle bin.
In other words, too bad they had to have their wrists slapped to fix it, but there was no malicious attempt.

They did it so users couldn't accidentally delete important files?? Sure would be nice if there was such thing as "root" on Windows so you could have files that every day users couldn't delete...
Rootkits in windows are becoming more and more of a problem. I found this interesting site the other day when looking for a rootkit detector: www.rootkit.com
Heh, my "confirm you're not a script" image is "sanity."
The cloaked directory is intended to prevent users from accidentally deleting important files
There's thousands of important files on a Windows system, and they don't need a rootkit to protect them. What's special about Norton files that make them extra-specially important?
I have had to uninstall Norton a few times and the 'Add and Remove Programs' feature in Windows did not work.
So, I had to go to this link and do it manually....talk about a pain in the #*$%.

Apparently insecure and/or incompetent sysadmins are behind the boom in "all-in-one-fix-'em-all" suites. Why not tackle the problems head-on yourself rather than relying on third party software which might actually jeopardise your entire system without you knowing it? And I found Norton Anti-virus to be a serious hog on system resources. It's safe to assume their other products are in the same league.
From what I can tell, if you uninstall it, you lose the system protected recycle bin (designed to prevent you from deleting your pr0n, actually it provides a hidden place for viruses to hide). Therefore, you're safe.
If you are still paranoid, reinstall it and run the update patch with fixes it.
Or, check out BlackLight Rootkit Elimination Technology, which is supposed to eliminate (or at least detect) the rootkit.

I've never much liked Norton Antivirus, and this just adds more fuel to the fire.
"...Symantec's update further protects computers by displaying the directory,"
That's great! Our product is now better, because we turned off something bad we were previously doing!
Now that's a nice spin!
My real problem is that my mom bought a PC at Christmas. While visiting (she's a couple time zones away), I did a little tuning (firewall, firefox, openoffice, etc.) Symantecs pisses me off so it got uninstalled (replaced with Avast). But ... did the uninstall really clean everything up? I can't check in person and I'm not going to walk my mom through rootkit detection unless neccessary.

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.

Steps of action when joe six-pack brings me a windoz box: 1. Uninstall Norton 2. Install AVG 3. Delete all "e"'s from everywhere 4. Install Firefox 5. Install Opera 6. Delete all Outlook shortcuts 7. Install Thunderbird 8. Install VLC and associate all media with it 9. Teach the guy to right-click/scan with AVG everything he downloads from the internet It worked nice in most occasions My 2p

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 must have missed something in the article. All it refers to is a "cloaked" directory. Now this shouldn't surprise anyone here. This is no different than how XP works normally. By default XP hides or "cloaks" protected system directories too, namely the System Volume Information folder in the root of each partition. The only way you can find them is by selecting to show hidden files and folders and to uncheck the "hide protected operating system files" option.
Now what is interesting is that even if you have administrative privileges, you by default do not have access to that folder. You have to manually add yourself to the security on it just to open it. From the article this seems to be the exact deal with the Symantec product. They are worried that an intruder may use the location to stash files. Well guess what? That is exactly what attackers do with the System Volume Info folder. It happened to me on a system that I had an older version of the Backup Exec remote client installed on. A well known hole, thankfully it was on a test system with no access. I noticed a huge amount of outgoing connects from the box and used disk space that I could not account for. After some minor digging around I managed to find everything stashed in that hidden system folder.
So what I would really like to know, and the article doesn't specify, is Symantec actually hooking into the kernel to hide the folder from Windows, or is it just setting the permissions on the folder in a way that is similar to the System Volume Information folder? If it is the later this is not a rootkit, it's just being sneaky. If they are hooking in, well shame on them.
I always knew that Norton guy was shady. Just look at the smug picture on the back of his books and other products. Plus he went and trademarked his name.

I remember a couple years ago when I still bought and used Norton/Symantec anti-virus; it kept claiming my subscription ran out and wouldn't update the definitions. So I uninstalled and reinstalled. Same problem. After doing some searching, I realized it had installed itself all over the registry and wouldn't get out. It took a good 2 hours of hand-editing to remove all traces of Symantec from my registry.
So much for "uninstall".
Which is why I never use their stuff anymore. Truth be told, I don't think they've done anything good since. Well. Since Peter Norton still loosened his tie and programmed for a living.
I can't think of any software of theirs that I would consider putting on a system, so I can't say I'm surprised by stuff like this.
You were mistaken. Which is odd, since memory shouldn't be a problem for you
I was getting directions to someplace the other day, the guy said the road there was paved with "good intentions". Damn, I can't remember the name of the place... think, think...
I may have missed something, but I saw nothing whatsoever in the article that sends information or provides external access without the users knowledge.
Isn't that what a rootkit does - allow unauthorized access?
Of course, it's hiding a directory, but as mentioned by other posters, Symantec has never been very secretive about that, they just didn't come out and announce in big flashing red letters that they were creating a hidden directory. Not a lie at all, as was the case with Sony.
Now, apparently there are a few folks here that seem to consider Symantec only a couple notches away from M$ on the slimeball ladder, but the fact is they write software that attempts to protect computers (typically from the gifts M$ has bestowed on the world). Personally, I only use their antivirus SW, since Windows does just fine bogging the one machine I run it on without any unnecessary help. To date, I have had far fewer issues with Windows machines using Norton Antivirus than those without it. In fact, it seems to me Norton AV is as important for Windows machines as a network connection.
Not that this isn't something to be aware of, but at best this is a potential security hole, not a rootkit. 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 - or doesn't anyone remember the SULFNBK virus?
Not to take up for symantec, but they do offere a free utility for removing all traces of their software. They have one for each piece of software as far as I know.

Ghost has saved my life so often that I seriously love that tool. Apart from that, you're right.
I just found out that Sygate has been acquired by Symantec and they discontinued the free for home use firewall.... Bummed!
Symantec has never even made anything, they just buy the competition.
I know they have that now, but they didn't at the time.
Worse, I don't trust Symantec to really remove their software. Why doesn't uninstall remove the software? Why do I need to uninstall then run "really uninstall" to really uninstall it?
You were mistaken. Which is odd, since memory shouldn't be a problem for you
...the norton recycle bin extension?
I know that nowadays norton products are mostly crap with near-to-none options, and all non-basic funtionality removed successively in every version, but this recycle bin extension comes from the good days and already saved my ass may times. (every time i typed something like Ctrl-N, Ctrl-S, Enter, and overwrote my just finished huge file with an EMPTY file.)
The direcory it used was not cloakrd in any other way than setting it to "hidden". I don't know if that changed in very recent versions (haven'T RTFA), but last time i used it (system works 2005) i could simply go into the directory and look what's inside it.
So maybe this is a common bug of virus scanners...
I even implemented something like this for my samba-shares. srue someone will come up with the "well, maybe it's a PEBCAK"-argument. but don't tell me you never did such an error and then whished to have the data back?
Any sufficiently advanced intelligence is indistinguishable from stupidity.
The symantec web site report on this states that it only affects 2005 and 2006, but I am running 2003 and it is also affected! The update fixes (supposedly) the issue. Nprotect can now be seen in the RECYCLED directory.

When you install Symantec (works with McAfee too I've been told) just set the system clock forward a few years. If it installs in 2010, but then finds itself in 2006, it'll think you have a 4 year subscription. I did this when I was still in the 'give me free stuff script kiddie' mode a few years back. A friend of mine just did it and confirmed that it still works. I switched to Debian and haven't had a problem with ClamAV.
Silly Symantec, not getting a real date online.
They have gaping holes in their firewall, so why not in more products?
Explanation: a fresh install of Windows XP on my father machine, SP1 because that was the CD that came with the machine, then an install of the Norton firewall that also came with the purchase - firewall set on as paranoid as the settings allowed... plug in network, and bam! Instant infection. There aren't any settings in the stupid product for "block everything" or anything either, just security levels or whatever it was. In any case, highest whatever apparently still left ports open... impressive.
The reinstall was because their firewall and antivirus had already failed to protect the computer btw. Why anyone would use thir products is way beyond comprehension. It's utter crap.

I've used this a lot lately when upgrading NAV, this is a removal tool which will nuke all traces of many Norton programs off a computer. Not as useful if you have, say, NAV and Ghost and just want to remove NAV, but if you only have NAV, this works for different versions. (As my family all uses NAV, but everyone always seems to have a different version, sticking this on my usb drive has been invaluable.)

I don't know if there is a relationship or not, but when the company was known as Norton (for Peter Norton), they had good products. When they transitioned to Symantec they seemed to make whatever they touched worse.
Norton's utilities were great, tiny, fast little tools that did what you wanted in a predictable way. A must have in the DOS days, and even early Window days. As Symantec the tools seemed to get more and more bloated. Then some of the tools had to be bought separately, costing more money. They took over PC Anywhere at some point, and made the tool so large that it was all but impossible to load into some DOS based systems (with plenty of RAM) and still be able to run the rest of the system properly. They took over WinFax and took out some of the best features and seemed to make it more prone to failures.
It's a pattern of theirs. And a great disappointment. And why I, also, no longer buy or use anything from them. First thing I do on new equipment that has their software is uninstall it. Same thing I tell others.

Is it just me, or does that sound like the Windows Registry?
