The same exploit used to crack part of the anti-piracy technology on the next-generation HD DVD format has been successfully used on the rival Blu-ray format, Wired News reported on Monday.
A hacker calling himself Muslix64, who also claims credit for the HD DVD crack that resulted in HD copies of films including "Serenity" appearing on the BitTorrent file-sharing network, takes partial credit for the Blu-ray crack, along with another programmer called Janvitos. Quote: "Oups, I did it again! ... In less that 24 hours, without any Blu-Ray equipment ... I managed to decrypt and play a Blu-Ray media file using my known-plaintext attack".
Neither of the exploits completely removes the fundamental security technology on the advanced DVD formats, but can work around the AACS encryption -- a digital rights management security -- when coupled with a particular movie's unique "key."
The victim is the Lord Of War Blu-Ray, with a size of 21,7GB. Two days after the announcement the proof was already posted: a 7-MB .m2ts file containing a 7 seconds warning at a resolution of 1920x1080.
