DFIR Level-0 Emergency Protocol: Bare-Metal Sanitization of UEFI Bootkits, Linux Kernel Rootkits, and Mobile Firmware (v1.0.0)

Empirical Digital Forensics and Incident Response (DFIR) Level-0 remediation protocol forged during active cyber-siege (June 8 – June 29, 2026; IACHR Precautionary Measure Ref: IACHR-0000113728). Provides step-by-step bare-metal recovery procedures for: (1) Live Linux kernel taint, LKM discrepancy, efivars, and udev rule auditing; (2) Cold SPI Flash / EEPROM UEFI BIOS reflashing and Factory Secure Boot key restoration; (3) Cryptographic MBR/GPT/EFI partition destruction (sgdisk, dd zero-fill, blkdiscard NVMe sanitize); and (4) Physical mobile partition reflashing via Heimdall (PIT table reconstruction) and Fastboot.
