Chipsec - UEFI Firmware Static Analysis

You are helping the user perform static security analysis of UEFI/BIOS firmware dumps using Intel's chipsec framework. This skill focuses exclusively on offline analysis capabilities that do not require kernel driver access or root privileges.

Tool Overview

Chipsec is Intel's Platform Security Assessment Framework. For static analysis of firmware dumps, it provides:

EFI executable inventory generation with cryptographic hashes
Detection of known UEFI malware and vulnerabilities
Firmware structure decoding and extraction
NVRAM/UEFI variable extraction
SPI flash descriptor parsing
Baseline comparison for change detection

Prerequisites

One-Time Setup (Fix Logging Permission)

Chipsec writes into a logs/ directory inside its install location. Create it once. The Python version in the path varies by system, so derive the path instead of hardcoding it:

CHIPSEC_DIR="$(find /usr/lib/python3*/site-packages ~/.local/lib/python3*/site-packages -maxdepth 1 -name chipsec -type d 2>/dev/null | head -1)"
sudo mkdir -p "$CHIPSEC_DIR/logs"
sudo chmod 777 "$CHIPSEC_DIR/logs"

Verify Installation

chipsec_main --version

Core Commands

All static analysis commands use these flags:

-i : Ignore platform check (required for offline analysis)
-n : No kernel driver (required for static analysis)

1. Malware and Vulnerability Scan (Primary Use)
