[InformationWeek]: Sony’s DRM system uses techniques normally employed by hackers and “can crash Windows.” Sony BMG Music Entertainment installed a “rootkit” in the copy-protection software distributed along with one of its music titles which exposes those systems to massive security vulnerabilities. Amatuears can’t even remove it. Sony has countered by saying that the copy-protection software is harmless, and issuing a patch, but hackers distributing code that could take advantage of security holes opened by Sony’s DRM. Great customer service, Sony! This is basically Spyware: its invisible, damages systems and resists removal.
