Firmware Extraction & Unpacking

Systematic extraction and unpacking of firmware binaries into analyzable filesystems and components. This skill provides methodical workflows for handling common and edge-case firmware formats, encryption, and obfuscation.

Extraction Workflow Overview

Follow this workflow sequentially for comprehensive firmware extraction:

1. Initial Assessment - Identify firmware type and components
2. Entropy Analysis - Detect encryption, compression, and structure
3. Signature Scanning - Locate filesystems and embedded files
4. Primary Extraction - Extract identified components
5. Filesystem-Specific Processing - Handle each filesystem appropriately
6. Verification - Validate extracted data
7. Nested Extraction - Process embedded firmware recursively
8. Documentation - Record extraction process and findings
