From Ed Felten: Slysoft Commercializes Next-Gen DVD Circumvention
"We’ve been following, off and on, the steady meltdown of AACS, the encryption scheme used in HD-DVD and Blu-ray, the next-generation DVD systems. By this point, Hollywood has released four generations of AACS-encoded discs, each encrypted with different secret keys; and the popular circumvention tools can still decrypt them all. The industry is stuck on a treadmill: they change keys every ninety days, and attackers promptly reverse-engineer the new keys and carry on decrypting discs.
One thing that has changed is the nature of the attackers. In the early days, the most effective reverse engineers were individuals, communicating by email and pseudonymous form posts. Their efforts resulted in rough but workable circumvention tools. In recent months, though, circumvention has gone commercial, with Slysoft, an Antigua-based maker of DVD-reader software, taking the lead and offering more polished tools for reading and ripping AACS discs.
