Analyzes UEFI bootkit persistence (SPI flash implants, ESP modifications, Secure Boot bypass, UEFI variable manipulation) using chipsec for firmware integrity verification, detecting known families like BlackLotus, LoJax, and MoonBounce. Use for UEFI malware analysis, firmware persistence investigation, or Secure Boot bypass detection.

# Analyzing UEFI Bootkit Persistence

## When to Use

- A compromised system re-establishes C2 communication after OS reinstallation or disk replacement
- Secure Boot has been tampered with, disabled, or shows unexpected Machine Owner Key (MOK) enrollment
- Firmware integrity verification fails against vendor-provided baselines
- Memory forensics reveals rootkit components loading during early boot phase
- Investigating advanced persistent threat (APT) campaigns known to deploy UEFI implants
- Auditing firmware security posture for enterprise endpoint hardening

**Do not use** for standard MBR-based bootkits on legacy BIOS systems without UEFI; use MBR/VBR bootkit analysis instead.
