DRM (is) for Dummies?

Three items recently caught my attention that I seemed worth sharing here:

  • At Boing Boing (which I’ve sadly removed from my list of newsfeeds a while ago, I couldn’t quite keep up) Cory Doctorow rants quite extensively about Amazon Unbox. I don’t think there’s a single point on which I disagree with him.
  • Via Tweakers, a Dutch site, I learned about Medialoper’s article regarding Zune and its wireless capabilities. It is planned to have support for wireless music sharing, but now it looks like in an attempt to prevent abuse, it’ll wrap any music shared that way in a special layer of chocoDRM to limit the recipient’s use, regardless of whether the track at hand is in need of such protection.
  • As discussed in Ars Technica, the recently developed DRM circumvention for iTunes has already been adapted to the new version (7.0). If I understand correctly how it works, this is not particularly shocking: It debugs the iTunes application, and at strategically placed break-points grabs blocks of unencrypted AAC audio straight from memory. Given that, the two biggest problems with adapting to 7.0 were that Apple apparently used a different compiler for this one, and of course the locations of the break-points will be in (sometimes not so) slightly different places. Since this approach completely ignores the communication with the iTunes Music Store — unlike JHymn which has been unable to circumvent the DRM since the release of 6.0 — Apple will have a much harder time thwarting this one.
