AACS has already been compromised in at least three widely known ways (
earlier
story #1 /
#2),
after DRM hackers posted on the Doom9 forums methods to retrieve and utilize
volume, and later, processing keys to copy every Blu-ray and HD DVD movie
released so far. The today a fourth method has appeared, as
poster jx6bpm reports he was able to find the 'sub device key' of the
PowerDVD playback software. That key identifies the player and allows it to
decode AACS protected titles. He also mentions that WinDVD and even AnyDVD is
hiding it better than PowerDVD. Oh well :-)
In related news, Slysoft has released a new version of
AnyDVD
now claims to be able to back up Blu-ray discs in addition to HD DVD, when
the volume keys of those discs have been located.
