The Sony rootkit tale, thankfully, is quickly gaining momentum in the mainstream press. The rootkit, for the unaware, is a piece of malware/spyware that installs itself deep within Windows to protect the contents of the music CD. Sony-BMG would have you believe that only “20 CD titles use this form of copy protection”. You’d like to believe that after getting emberassed about using a rootkit to protect their music, that Sony Executives would come clean about how many releases are ‘infected’ by the spyware.
