Newest Audio CD DRM Proves Ineffective 703

The Importance of writes "As noted previously, a couple of weeks ago BMG released a new CD by Anthony Hamilton that included DRM. Slashdot readers speculated that the system wouldn't work. Now there is a report proving it doesn't work by Alex Halderman, a graduate student at Princeton's computer science department and the author of an earlier, definitive report (PDF, HTML version) on first generation CD copy protection.

Newest Audio CD DRM Proves Ineffective

    Start with a Windows 2000/XP system with empty CD drives. Be sure to reboot the computer first to ensure MediaMax is not running.

    1. Click the Start button and select Control Panel from the Start Menu.
    2. Double-click on the System control panel icon.
    3. Select the Hardware tab and click the Device Manager button.
    4. Configure Device Manager by clicking "Show hidden devices" and "Devices by connection," both from the View menu.
    5. Insert the Anthony Hamilton CD into the computer and allow the SunnComm software to start. Observe that the SbcpHid device driver is added to the Device Manager list when MediaMax runs for the first time.

    At this point you can attempt to copy tracks from the CD with applications like MusicMatch Jukebox or Windows Media Player. Copies made while the driver is active will sound badly garbled, as in this 9-second clip [10].

    Next, follow these additional steps to disable MediaMax:

    1. Select the SbcpHid driver from the Device Manager list and click "Properties" from the Action Menu.
    2. Click the Driver tab and click the Stop button to disable the driver.

    With the driver stopped, you can verify that the same applications copy every track successfully.

    And oh, yeah, this work is a blatant DMCA violation.

    The DRM feature works in tandemw ith the DMCA. Alex Halderman can expect to find himself relocated to a federal prison soon. I bet that he won't be writing about the weakness of DRM systems anymore.

    See, DRM does work when you make it illegal to point out where it is weak.
  • You don't have to do all the stuff the article lists, just hold down the left shift key when the disk load. Then, do not double click the drive at all, or it will also autorun (if you want to take a peek, use "Explore"). It also sounds like there's no protection at all in Linux.
    • From the article:

      Windows users who haven't disabled autorun can suspend it when they play a SunnComm-protected disc by holding down the shift key for a few seconds while inserting the CD. They can then copy the data normally.
    • If the DRM prog runs only on Windows, and you happen to own a Mac or Linux box, is that against DMCA? If so, expect some sh** to hit the fan. Either M$ is going to make a deal with RIAA and then sue Apple for making computers at all or some Linux or Mac owner is going to get more than a little pissed and finally give DMCA a real run for its money. Oh, well. A guy can dream, anyway.

        then: "I wonder if I can download the song off kazaa"

        At which point he spends about 30 seconds searching for the song, which some more technologically clued in person has kindly made available.

        Users don't grok shift keys and drivers and EULA's. They do grok kazaa however.
      • Sure, that's true. But does that deter copying? All it does it drive them to Kazaa to download it from the 20% of us that are clue-full.

        All it deters is the average joe ripping it to their hard drive. (Which by the way is legal). Anyone willing to download it from kazaa, probably will anyway. Thus whether or not they could rip it themselves, seem moot.

  • So they rely on the autorun setting on cd's to load the device driver for them? that's pretty stupid -- on windows it's enabled by default (typical) but most companies disable it because it's a security risk.

    The Mac got hit pretty hard with an autorun virus that ended up shipping on many cd's. As a result many Mac users disabled this in OS 9, and I believe OS X has it disabled by default.

    This might be effective on most windows home computers whose owners don't change the default setting, but I'm wondering how long before that driver gets infected with a virus....

    It loads a custom device driver via 'autorun' when you stick the CD in.

    So if you hold shift, disable autorun, or run an OS that doesn't do autorun, the CD might as well have no copy protection whatsoever.

    This is about as effective as putting a sticker on the front that says 'Pretty please do not attempt to extract data from this CD on your computer'.

      "This is about as effective as putting a sticker on the front that says 'Pretty please do not attempt to extract data from this CD on your computer'."

      Gotta wonder, why hasn't the RIAA tried putting little "Do's and Dont's" pamphlet in CDs? I mean, seriously, the RIAA has done *nothing* to educate people about what's legal and what isn't. This is why people are appearing in court with a surprised expression on their faces. If the RIAA, ages ago, had insisted that record labels put little pamphlets in their CD's saying "please don't copy and give to a friend", then their stance would be a little easier to handle.

      The RIAA says their problems are because everybody's a thief, I say the RIAA's problems are a direct result of their own ignorance. At least the movie industry is smart enough to put a list of don't on every movie. Interestingly enough, there aren't as many DVD rips out there.

    1.2. Your rights to use the Digital Content are conditioned on your ownership of a license to use and possession of the original Compact Disc (CD) media and are terminated in the event you no longer own or possess the original CD media. (This apparently prohibits using copied tracks as backups in case the original disc is lost, stolen, or destroyed.)

    So if the CD fails to remain usable through normal wear and tear, does that put the publisher in breach of contract? They've effectively granted me a license that they are going to renege on should the physical media degrade.

    They've got to make up their minds! Is it a physical good, or a digital good? Did I buy a license and the CD was just a nice way for them to fulfill their promise that I'm licensed to use the content? Did I buy a plastic disc (for $15) which I'm free to do with as I please?
    • One of my more common-sense arguments about copy protection is that you can either restrict copying or charge for replacement media, but not both. As we know, CDs will not last forever, no matter how gingerly treated. So either let us back it up, or give us a replacement if it breaks.

      This is one reason why software copy protection never worked. People who didn't want to pirate software still wanted a program to defeat it so they could make a backup.

    Reading over the article, I have a few unanswered questions that almost make me want to pick up the CD just to see for myself:

    1) Does the software ask your permission to install the device driver that mungs your ripped tracks? Note that there are two pieces of software on the CD: one that uses a device driver to prevent a CD ripper from getting a copy of the track onto the computer, and another that controls the DRM on the WMA files. The author didn't use the latter because it required accepting a EULA, but the former he obviously was able to test. Thus I suspect that it doesn't ask you, however it's possible that it does but doesn't require acceptance of a EULA. I doubt that, however.

    2) Are the tracks rippable in Linux? Obviously the WMA wouldn't be, as they require software to handle the DRM. But without the drivers, the tracks on the CD appear to be rippable in Windows, and thus I assume, also in Linux or any other OS that doesn't run Windows code.

    3) If (2) is true, then how long until Linux is considered to be circumvention software?

    4) Does the EULA include a provision preventing you from bypassing the device driver?
  • We already know you can't have your cake (playable on standard CD players) and eat it (uncopyable).

    The questions are:
    Will consumers realize the difference between CDs and non standard discs?
    Will the media, and ultimately the RIAA, realize any such attempt is guaranteed to fail uness the hardware can be fully controlled?

    What does it take for these people to realize it's a losing battle?

    Once again the wagon of DRM has been rammed off the road by the candletruck of innovation.

    John goes to the store, buys his Comin' from Where I'm From CD, gets home, opens it, listens to it on his old stereo. He finally gets around to ripping it to put it on his portable player (older, so no WMA), and it doesn't work. He tries the audio player again, it's fine. Computer again, it doesn't work. By now it's been thirty days, and besides, the CD's open; there's no hope of returning it. What does he do?

    P2P. He asks his friends, they set him up with a client. He has some respect for copyright, but his practical interest takes over, and he grabs the album off P2P. But now he has a client installed, so he's only three clicks and a sacrifice of morals (against a company that just screwed him) away from further downloading.

    The moral of the story? DRM limitations fuel P2P. This story depends on a portable player that doesn't do WMA, but there are many other inconveniences. What if he doesn't use Windows or Mac (that's me)? What if he's an audiophile who can hear the difference between WMA and FLAC?

    Besides, the article says you can burn the tracks a limited number of times. That's right, without any circumvention at all, the DRM is totally ineffective! I haven't checked, but I'm willing to bet the music is all over the P2P networks. DRM is completely worthless: if there were any competition (there isn't), the idea would have died years ago.

    Like many iPod users, I actually buy much more music than I did previously. New listening device creates new spaces for listening music and thus increases demand. However, I am not rich enough to buy EVERYTHING I want to listen - usually when I enter a store, 4-5 albums catch my interest, but I can afford to walk out only with 2-3 of them. Obviously, I avoid CD's with stickers like "this CD is copy protected". I know the protection is probably easy to bypass, but why should I bother? I just choose the 2-3 albums without the protection. And here's a weird thing - whenever I put back a "copy protected" CD on the store shelf (carrying in my basket the non-protected ones) echo brings me the sounds of a gunshot and a voice shouting "ouch! my foot!" somewhere in the distance.
