Hack exposes AACS 'hole'
Hackers appear to have figured out how to access one of the crucial HD DVD encryption keys without having to authorise the data - potentially rendering the latest attempt to block such activity useless.
The crack, posted on the Xboxhacker website, uses a standard, unmodified Microsoft's Xbox 360 HD DVD drive to hand over a disc's Volume ID without ensuring AACS has authenticated it first. Since no authentication is performed, even if the Volume ID has been rejected by the AACS Licensing Authority - the organisation that maintains the copy-protection system - it can still be used.
