After making the headlines with one piece of news few were happy to hear about, Sony released a patch that reveals hidden files that are automatically installed to hard drives when some of its music CDs are played on personal computers.
Considering rootkits are invisible to many detection
tools, including antivirus, host and network intrusion-detection sensors and antispyware products, having such an important company as Sony use these elements was very disturbing and caused a very strong reaction from the public.
Sony admitted using this software in order to prevent further piracy as the copy protection technology limits how many times a CD can be copied, was included on about 20 titles, including discs from The Bad Plus and Vivian Green, among others.
Furthermore, Sony spokesman John McKay said the technology had been on the market for about eight months and there had been no major complaints before Windows expert Mark Russinovich posted a Web log report on how he found hidden files on his PC after playing a Van Zant CD.
The downloadable fix is called "Service Pack 2" but it should not be confused with Microsoft's Service Pack 2 for Windows XP.
