CD DRM Makes Computers Less Secure
Yesterday, Sysinternals's Mark Russinovich posted an excellent analysis of a CD copy protection system called XCP2. This scheme, created by British-based First4Internet, has been deployed on many Sony/BMG albums released in the last six months.
Context & Ripple Effects
Mark Russinovich's Sysinternals analysis of the Sony rootkit revealed that First4Internet's XCP2 copy protection hides itself on users' machines using classic rootkit techniques — the same concealment tricks used by malicious software. The finding turned an anti-piracy story into a security story overnight, forcing Sony/BMG into damage control with a promised patch within days.
First-order effects
- Consumers who played recent XCP2-protected Sony/BMG albums have compromised Windows machines — the hidden software degrades system security and resists removal, and Sony is scrambling to issue a patch for the copy-protected CDs.
- First4Internet and Sony/BMG face immediate reputational exposure, with the 'mysterious' nature of their first update attempt deepening rather than defusing scrutiny.
Second-order effects
- Malware authors are already exploiting the cloak: attackers have been observed piggybacking on the rootkit to hide game cheats in World of Warcraft, showing how DRM code becomes attack infrastructure.
- Other labels and DRM vendors must now weigh whether stealth-based copy protection survives the publicity, while antivirus vendors face pressure to detect and flag commercial rootkits.
Third-order effects
- The episode points toward treating vendor-installed protection software under the same security standards as third-party code — a line of thinking that echoes today's supply-chain failures like the UEFI Secure Boot key leak across 200+ device models.
- If DRM keeps trading user security for anti-copy enforcement, expect regulatory and platform-level intervention to constrain what content companies can silently install on consumer machines — though the form that oversight takes remains genuinely uncertain.
The trend: Copy-protection technology is colliding with endpoint security, forcing the industry to treat DRM software as part of the threat model rather than apart from it.
