What a ‘rootkit’ type of environment will do in this case (note; Now patched) is very simple. It does not matter what sort of content is on the CD/DVD from whatever the type of company may be.
It opens up a very well known exploit on a personal computer and in this case Microsoft Windows. By hiding files in this type of method gives all of the people that are out there writing malware, spyware, trojans or a virus is a very easy delivery mechanism. As all they need to do is have the file that they intend to get into your computer system to do whatever is in there mindset of evil is have the filename begin with $SYS$ and that is it.
The file is now hidden and protected from antivirus software detection and spyware monitoring. This results in the piece of software remaining undetected on a PC for a much longer time than what is considered safe. The offending piece of software can then access your personal data and transmit this information via an internet connection for whatever purpose they choose to use it.
By having a delivery mechanism like this the writer of such annoying and costly security breaches spreads across all forms of computing environments from individual, business and government sectors. It remains hidden and protected from detection as it is protected by a major corporation having the masking software on your pc for this case musical Digital Rights Management (DRM)
With the world climate that we live in today where computers are used as a tool for attack and defence of terrorism there can be no leaks of secure information. This issue greatly transcends well beyond the simple issue of musical DRM. This is a major breach of security that has ramifications at all parts of society. A piece of software that is hidden behind such a product is a breach of any security policy of any country.
