Experts: Sony plan widens security hole

BOSTON (AP) -- The fallout from a hidden copy-protection program that Sony BMG Music Entertainment put on some CDs is only getting worse. Sony's suggested method for removing the program actually widens the security hole the original software created, researchers say.
Sony apparently has moved to recall the discs in question, but music fans who have listened to them on their computers or tried to remove the dangerous software they deposited could still be vulnerable.
"This is a surprisingly bad design from a security standpoint," said Ed Felten, a Princeton University computer science professor who explored the removal program with a graduate student, J. Alex Halderman. "It endangers users in several ways."The "XCP" copy-protection program was included on at least 20 CDs
, including releases by Van Zant, The Bad Plus, Neil Diamond and Celine Dion.
When the discs were put into a PC - a necessary step for transferring music to iPods and other portable music players - the CD automatically installed a program that restricted how many times the discs' tracks could be copied, and made it extremely inconvenient to transfer songs into the format used by iPods.
That antipiracy software - which works only on Windows PCs - came with a cloaking feature that allowed it to hide files on users' computers. Security researchers classified the program as "spyware," saying it secretly transmits details about what music the PC is playing. Manual attempts to remove the software can disable the PC's CD drive.
The program also gave virus writers an easy tool for hiding their malicious software. Last week, virus-like "Trojan horse" programs emerged that took advantage of the cloaking feature to enter computers undetected, antivirus companies said. Trojans are typically used to steal personal information, launch attacks on other computers and send spam.
Stung by the controversy, Sony BMG and the company that developed the antipiracy software, First 4 Internet Ltd. of Oxfordshire, United Kingdom, released a program that uninstalls XCP.
But the uninstaller has created a new set of problems.
To get the uninstall program, users have to request it by filling out online forms. Once submitted, the forms themselves download and install a program designed to ready the PC for the fix. Essentially, it makes the PC open to downloading and installing code from the Internet.
According to the Princeton analysis, the program fails to make the computer confirm that such code should come only from Sony or First 4 Internet."The consequences of the flaw are severe," Felten and Halderman wrote in a blog posting Tuesday. "It allows any Web page you visit to download, install, and run any code it likes on your computer. Any Web page can seize control of your computer; then it can do anything it likes. That's about as serious as a security flaw can get
Sony BMG spokesman John McKay did not return calls seeking comment. First 4 Internet was not making any comment, according to Lynette Riley, the office manager who answered the company's phone Tuesday evening in England.
Mark Russinovich, the security researcher who first discovered the hidden Sony software, is advising users who played one of the CDs on their computer to wait for the companies to release a stand-alone uninstall program that doesn't require filling out the online form.
"There's absolutely no excuse for Sony not to make one immediately available," he wrote in an e-mail Tuesday.
Other programs that knock out the original software are also likely to emerge. Microsoft Corp. says the next version of its tool for removing malicious software, which is automatically sent to PCs via Windows Update each month, will yank the cloaking feature in XCP.
Sony BMG said Friday it would halt production of CDs with XCP technology and pledged to "re-examine all aspects of our content protection initiative." On Monday night, USA Today's Web site reported that Sony BMG would recall the CDs in question.
Sony to suspend making antipiracy CDs

WASHINGTON (AP) -- Stung by continuing criticism, the world's second-largest music label, Sony BMG Music Entertainment, promised Friday to temporarily suspend making music CDs with antipiracy technology that can leave computers vulnerable to hackers.
Sony defended its right to prevent customers from illegally copying music but said it will halt manufacturing CDs with the "XCP" technology as a precautionary measure. "We also intend to re-examine all aspects of our content protection initiative to be sure that it continues to meet our goals of security and ease of consumer use," the company said in a statement.
The antipiracy technology, which works only on Windows computers, prevents customers from making more than a few copies of the CD and prevents them from loading the CD's songs onto Apple Computer's popular iPod portable music players. Some other music players, which recognize Microsoft's proprietary music format, would work.
Sony's announcement came one day after leading security companies disclosed that hackers were distributing malicious programs over the Internet that exploited the antipiracy technology's ability to avoid detection. Hackers discovered they can effectively render their programs invisible by using names for computer files similar to ones cloaked by the Sony technology.
A senior Homeland Security official cautioned entertainment companies against discouraging piracy in ways that also make computers vulnerable. Stewart Baker, assistant secretary for policy at DHS, did not cite Sony by name in his remarks Thursday but described industry efforts to install hidden files on consumers' computers.
"It's very important to remember that it's your intellectual property, it's not your computer," Baker said at a trade conference on piracy. "And in the pursuit of protection of intellectual property, it's important not to defeat or undermine the security measures that people need to adopt in these days."
Sony's program is included on about 20 popular music titles, including releases by Van Zant and The Bad Plus.
"This is a step they should have taken immediately," said Mark Russinovich, chief software architect at Winternals Software who discovered the hidden copy-protection technology Oct. 31 and posted his findings on his Web log. He said Sony did not admit any wrongdoing, nor did it promise not to use similar techniques in the future.
Security researchers have described Sony's technology as "spyware," saying it is difficult to remove, transmits without warning details about what music is playing, and that Sony's notice to consumers about the technology was inadequate. Sony executives have rejected the description of their technology as spyware.
Some leading antivirus companies updated their protective software this week to detect Sony's antipiracy program, disable it and prevent it from reinstalling.
After Russinovich criticized Sony, it made available a software patch that removed the technology's ability to avoid detection. It also made more broadly available its instructions on how to remove the software permanently. Customers who remove the software are unable to listen to the music CD on their computer.
