Sony copy-protected CDs apparently contain rootkits
This article details the finding of an actual root kit (that is, a program designed to remain hidden from security software by cloaking itself and pretending to be part of the OS), that turned out to have been installed by a Sony copy-protected CD.
“I ran a scan on one of my systems and was shocked to see evidence of a rootkit. Rootkits are cloaking technologies that hide files, Registry keys, and other system objects from diagnostic and security software, and they are usually employed by malware attempting to keep their implementation hidden”
The EULA, also, apparently contained no mention of it.
This is probably illegal. I won’t be surprised in the least if Sony gets royally sued for this.
