Apple has closed a security hole that allowed a program to connect to the iTunes Music Store and buy songs stripped of antipiracy protections, reports CNET News.com. “The PyMusique software, created by a trio of independent programmers online, emerged last week as a copy protection-free back door into the popular iTunes store. One of the creators was Jon Johansen, the Norwegian programmer responsible for releasing DVD-copying software in 1999. Apple released a statement Monday saying the problem had been fixed, and that some iTunes customers would need to upgrade their software. ‘The security hole in the iTunes Music Store which was recently exploited has been closed, and as a consequence the iTunes Music Store will now sell music only to customers using iTunes version 4.7,’ the company said in a statement.”
