The crater.sys process is a component driver file of certain applications that are embedded with DRM (Digital Rights Management) technology from First 4 Internet, which is a company that develops copy-protection protocols for Windows programs, multimedia hardware devices and digital audio/video player applications. The crater.sys driver file has been reported by many users as a cloacked system process packaged into the firmware components and device driver software utilities of some CD/DVD-ROM and RW drives from Sony, particularly optical media disk models that are integrated with copy-protection protocols and content security functionalities by First 4 Internet. The crater.sys driver file is placed in the system upon the installation of the firmware resources and device driver software components of these hardware devices and applications, which also means the crater.sys process is included as one of the resource files and component libraries packaged into the installer distributions of these DRM programs, firmware utilities and drivers.
