Analyzes bootkit and advanced rootkit malware infecting the Master Boot Record (MBR), Volume Boot Record (VBR), or UEFI firmware for below-OS persistence, covering boot sector analysis, UEFI module inspection, and anti-rootkit detection. Use when compromise survives OS reinstallation or antivirus/EDR fails to detect malware despite clear infection signs.

# Analyzing Bootkit and Rootkit Samples

## When to Use

- A system shows signs of compromise that persist through OS reinstallation
- Antivirus and EDR are unable to detect malware despite clear evidence of compromise
- UEFI Secure Boot has been disabled or shows integrity violations
- Memory forensics reveals rootkit behavior (hidden processes, hooked system calls)
- Investigating nation-state level threats known to deploy bootkits (APT28, APT41, Equation Group)

**Do not use** for standard user-mode malware; bootkits and rootkits operate at a fundamentally different level requiring specialized analysis techniques.
