United States Computer Emergency Readiness Team. “First 4 Internet XCP DRM vulnerabilities.” US-CERT, November 16, 2004.

Summary: Both Sony's DRM software and their uninstaller are dangerous; using either one opens your computer to abuse by system crackers. The CERT offers some advice about how to avoid such problems:

• Do not run your system with administrative privileges. Without administrative privileges, the XCP DRM software will not install.
• Use caution when installing software. Do not install software from sources that you do not expect to contain software, such as an audio CD.
• Read the EULA (End User License Agreement) if you do decide to install software. This document can contain information about what the software may do.
