Blu-Ray DVD copy protection cracked!

25 January 2007

First HD DVDs were cracked; now Muslix64 has gone for an encore and cracked the protection on Blu-Ray DVD's so that they can be ripped in unencrypted form. It seems that he didn't even need a Blu-Ray player to figure out how to do it, he found an attack that sidesteps the AACS (Advanced Access Content System, which does anything but let you access content) by finding the key used to encrypt the media data hidden inside the cyphertext. To prove that he was successful, he posted a ripped copy of Lord of War to the Net, which was subsequently taken down because everyone and their backup started downloading it. The utility he wrote is just 18kb in size, and has probably hit the filesharing networks by now. Remember to watch out for trojan horses, everyone.
