Not long ago, on news Web 2.0 Digg aggregator information was appearing on evasion the protection for copying HD DVD and Blu Ray-disks. After a formal patch was released to protect high-density disks, someone BtCB has reported that it had been forced by him on the next day. Significantly, the key was found in the web site Freedom to Tinker in the form of Japanese poem of three strophes, haiku. It is turned out that the poem coincided with the method of decryption of 128-bit key, elaborated by the licensing government (AACS). Using the key, the user can get an access to all protected blocs.
