SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill helps security analysts understand how a firmware image is structured and how its boot chain and update flow lead to the device's behavior, enabling precise artifact tracing and risk assessment.

Core Features & Use Cases

Map outer container, partition table, bootloader, kernel, rootfs, config blobs, and update metadata.
Trace the boot or update chain from boot ROM through secure boot, kernel, and services, recording credentials, certificates, and config usage at each stage.
Preserve extracted components and create an evidence chain to support reproducible analysis and artifact discovery.

Quick Start

Preserve the original image and patches as separate artifacts, map the layout, and trace the boot/update flow in a single end-to-end workflow.

FAQPage Schema

How do I map firmware partitions and trace the boot chain in an embedded device?▼

To map firmware partitions and trace the boot chain, map the firmware image into partitions, bootloader, kernel, and rootfs. Then trace the boot sequence from boot ROM through secure boot to services, recording offsets, sizes, hashes, and trust boundaries.

What is firmware layout analysis for security assessment?▼

Firmware layout analysis is the process of mapping outer containers, partition tables, and update metadata to reveal decisive artifacts. It identifies the boot sequence, trust boundaries, and reachable components to enable precise artifact tracing and risk assessment.

How do I extract firmware components while preserving evidence for reproducibility?▼

To extract firmware components while preserving evidence, keep the original image and patches as separate artifacts. Map the layout and trace the boot or update flow, creating an evidence chain that documents offsets, hashes, mount points, and config paths.

Can I trace credentials and certificates used during the embedded device boot sequence?▼

Yes, you can trace credentials and certificates used during the boot sequence. The firmware layout analysis records credentials, certificates, and config usage at each stage of the boot or update chain, from boot ROM through secure boot to running services.

What's the best way to analyze a firmware dump for update flow and trust boundaries?▼

The best way to analyze a firmware dump for update flow is to map the update metadata alongside partition tables and config blobs. This identifies trust boundaries, traces the update chain, and reveals reachable artifacts within the embedded device.

Does firmware layout mapping work with device update flows and raw firmware dumps?▼

Yes, firmware layout mapping works with device update flows and raw firmware dumps. It is specifically applied to embedded devices, firmware dumps, and update flows to identify the boot sequence, trust boundaries, and reachable artifacts while preserving originals.
