Sony's DRM (Digital Rights Management) is getting tougher nowadays, and its become a big people vs the man war on piracy. Sony has come out with file on its CD's called rootkit that installs itself on your computer and hides itself from the OS. The rootkit file makes any other file with the name $sys$ in it, practically invisible and no amount of searching will find it. Turns out that hackers can easily exploit this matter, and Sony has not really stepped up with protection. Sony has though, suspended use of rootkit and has recalled some of its affected discs. -MaximumPC
