CD Copy Protection: The Road to Spyware

Advocates of DRM (copy protection) have been keeping their heads down lately, while they try to figure out what went wrong in the SonyBMG DRM spyware fiasco. No doubt they’ll try to explain it away as an anomaly — just a little speed bump on the road to the effective, unobtrusive DRM future that they’re sure will be arriving any day now.

There are some problems with this story. For starters, we’re not talking about a single DRM system — we’re talking about two totally separate systems (XCP and MediaMax), developed by rival companies, both of which turned out to be spyware and to endanger users, in strikingly similar ways. Is this just a coincidence?

Of course it’s not. If we look carefully at CD copy protection as a technical problem, we’ll see why DRM designers are drawn to spyware tactics as their best hope of stopping copying. Let me explain why.

Hidden Feature in Sony DRM Uses Open Source Code to Add Apple DRM

For weeks, the blogosphere has been abuzz with tales of intrigue about Sony’s XCP copy protection system. Among the strangest revelations was that XCP itself infringes on the copyrights to several open source software projects. In one case, Sam Hocevar found conclusive evidence that part of XCP’s code was copied from a program called DRMS, which he co-authored with DVD Jon and released under the terms of the GPL open source license. What made this finding particularly curious is that the purpose of DRMS is to break the copy protection on songs sold in Apple’s iTunes Music Store. Why would XCP rip off code intended to defeat another vendor’s DRM?

MediaMax Permanently Installs and Runs Unwanted Software, Even If User Declines EULA

In an earlier post I described how MediaMax, a CD DRM system used by Sony-BMG and other record labels, behaves like spyware. (MediaMax is not the same as XCP, the technology that Sony-BMG has recalled; Sony-BMG is still shipping MediaMax discs.) MediaMax phones home whenever you play a protected CD, automatically installs over 12 MB of software before even displaying an End User License Agreement, and fails to include an uninstaller.
