Just a few days after a hole was found in Apple' iTunes Online Music Store that allowed users to purchase songs without digital rights management technology (DRM) attached, Apple has confirmed that its online music downloading breakout star, iTunes is all sealed. The company now requires all users who purchase tracks from iTunes to use iTunes 4.7.1 When Travis Watkins, Cody Brocious and Jon Johansen AKA the guys behind the DVD Content Scrambling System to decrypt DVDs, discovered the hole, new software called PyMusique was developed to hack into Apple's online music store iTunes to offer its songs free of anticopying protection. PyMusique allowed iTunes subscribers to purchase and re-download tracks that are free of Apple's Digital Rights Management (DRM) copyright protection. Apple has blocked PyMusique users with the changes to close hole. Previous versions of iTunes added the protection after the download was complete, and PyMusique can block that installation.

"The security hole in the iTunes Music Store which was recently exploited has been closed, and as a consequence the Music Store will now sell music only to customers using iTunes version 4.7.1," Apple said in a statement.
