So one of the things Sony’s DRM rootkit/spyware/malware does is completely conceal any files with names beginning with
$sys$. Another thing that it does is prevent you from burning CDs with copy protected material on them. Well, one blog reports that if you rename your CD burning software so that the copy protection software conceals it, the other part of the copy protection software won’t stop you from burning the CDs.
Usually Mac OS X users are not subjected to the same indignities that Windows users are when it comes to DRM. In Sony’s case, however, users are subjected to slightly different but equally bad treatment — certain CDs actually install kernel extensions on your computer when you insert them for the first time. At least on a Mac you have to enter your password to permit the software to be installed, something I would not recommend doing.
Update: The thing about using some features of Sony’s copy protection software to evade other features probably doesn’t work.
