It took them nearly a month, but the Advanced Access Content System (AACS) Licensing Authority has finally confirmed that hackers have acquired "title keys", allowing them to decrypt HD movies.
A consortium of movie studios and technology companies backing the encryption system for high-definition DVDs on Thursday confirmed that hackers have stolen "title keys" and used them to decrypt high-definition DVDs through flaws in DVD player software.
