  • The hacker “Muslix64” who cracked HD DVD strikes again by defeating Blu-ray Disc encryption!!!

    The HD-DVD hack is a java based command line utility (source code is AVAILABLE!) that decrypt video files (.evo) from a disk that you own, to your hard drive and you can play them back...

    Basically on Blu-ray disk, “Muslix64” is using a plain text attack on data... ”

    This is a very basic, but [powerful] crypto attack that I have used to decrypt both [HD DVD and Blu-ray] formats,” he wrote.

     “After reading posts of people trying to get the keys in memory, I realized, I have a different way of looking into the problem…A lot of people try to attack the software, I'm attacking the data!” ” So I spent more time analysing the data, to look for patterns or something special to mount my known-plaintext attack,”

    Muslix64 explains. “Because I know the keys are unprotected in memory, I can skip all the [painful] process of code reversal. ” read more at http://dailytech.com/Bluray+Encryption+Defeated/article5795.htm



     

  • TrueCrypt: a Free open-source disk encryption for Windows XP/2000/2003
    Main Features:

    • It can create a virtual encrypted disk within a file and mount it as a real disk.
    • It can encrypt an entire hard disk partition or a device, such as USB memory stick, floppy disk, etc.
    • Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:
      1) Hidden volume
      2) No TrueCrypt volume can be identified (TrueCrypt volumes cannot be distinguished from random data).
    • Encryption algorithms: AES-256, Blowfish (448-bit key), CAST5, Serpent (256-bit key), Triple DES, and Twofish (256-bit key). Supports cascading (e.g., AES-Twofish-Serpent).
    • Based on Encryption for the Masses (E4M) 2.02a, which was conceived in 1997.
