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.
Prerequisites
- chipsec framework for SPI flash dumping, UEFI variable inspection, and firmware security modules
- UEFITool / UEFIExtract for firmware volume parsing and DXE driver extraction
- Python 3.8+ with struct, hashlib, subprocess, and os modules
- Bootable Linux live USB for offline analysis (avoid running compromised OS)
- Volatility 3 for memory forensics of boot-phase artifacts
- YARA with UEFI malware rule sets for pattern-based detection
- Access to vendor firmware baselines for integr…
