By moving the flashing process into a protected execution environment, it eliminates common software-based attack surfaces. While this significantly improves platform resilience against malware, it often "wraps" BIOS updates in complex, nested structures that cannot be read or modified by standard tools like Functionality of the Extractor The extractor utility, often distributed as part of BIOSUtilities , performs several critical technical tasks: Parsing PFAT Images
