Unwritten, album on CD, by Natasha Bedingfield (2005)
The Sony BMG record label released many CDs in 2005 with "XCP content protection softwarwe." When the CD was inserted into a computer running the Windows operating system, the CD surreptitiously installed a "rootkit" that disabled the computer from being able to "rip" audio tracks from CDs. The XCP rootkit made afflicted computers vulerable to further attacks by hackers unaffiliated with Sony. Despite the risk it posed to the computer, it was illegal under the Digital Millenium Copyright Act (DMCA) for users to remove the rootkit. The scandal resulted in class-action lawsuits against Sony and the making of a regulatory exception to the DMCA.
