Sony CD protection sparks security concerns
November 1, 2005
In the PC-tuning application, a feature called the Norton Protected Recycle Bin creates a hidden directory on Windows systems. The feature is meant to help people restore modified or deleted files, but the hidden folder might not be scanned during scheduled or manual virus scans, Symantec said in an advisory released Tuesday.
"This could potentially provide a location for an attacker to hide a malicious file on a computer," Symantec said. The Cupertino, Calif., security provider is not aware of any attempts by hackers to conceal malicious code in the folder. "This update is provided proactively to eliminate the possibility of that type of activity," it said.
Symantec's alert has echoes of Sony BMG Music Entertainment's recent PC security fiasco. The record label was found to be shipping copy-protected compact discs that planted so-called rootkit software on the computers that played them. The rootkit technology also offered a hiding place for malicious software.
When the recovery feature was first introduced, hiding the directory helped ensure that a user would not accidentally delete the files in it, Symantec said.
"In light of current techniques used by malicious attackers, Symantec has re-evaluated the value of hiding this directory," the company said in its advisory.
Security monitoring company Secunia rates the issue "not critical." Symantec itself deems the risk impact "low."
Symantec credits Mark Russinovich, the Sysinternals researcher who also investigated the Sony rootkit, and F-Secure, a Finnish security company that has a rootkit detection product, for helping it address the SystemWorks issue.
The Norton update will display the previously hidden "NProtect" directory in the Windows interface, which will allow it to be scanned by antivirus products, Symantec said. The new version is available through the Symantec LiveUpdate service. Installing the software will require a system reboot.

Besides, Symantec's security and such have been getting worse and worse since 2000.
Long live Avast and AVG.
I have completely abandon Norton Antivirus. It has turned into such piece of crap. Talk about a resources hog.

- What I have not seen mentioned in any of the news items on this issue, and that I think deserves broader play, is the fact that Symantec's fix is only for the 2004 through 2006 versions of their utility suite. 2003 and earlier suffers from the same problem but if you want to fix that, you are out of luck. First you have to pay for an upgrade and then apply the patch. But I have a better idea. Out of curiosity, I downloaded Zone Alarm's antivirus suite and scanned with it. I found 8 infections that Norton had let past, 6 of them hiding in the NPROTECT folder. This is curious since I have never used Norton Protection for my recycle bin. Apparently, it is installed whether you want it or not and all you can do is toggle whether or not it is actually used. So let's see the score: Norton is slipshod about preventing infections, it provides a cozy hiding place for them that they are now using, and if you want to destroy that hiding place, you have to pay money to Symantec for the priviledge. I think uninstalling is a far better idea.
