What problem does it solve? CTF and reverse-engineering tasks involving firmware images often stall because analysts jump straight to interesting files without understanding partition layout, boot order, or update verification. This Skill provides a structured workflow for unpacking firmware images, tracing boot and update chains, and proving how a device surface reaches the decisive artifact. ## Core Features & Use Cases - Image Layout Mapping: Identify containers, partition tables, compression, filesystems, and nested images while recording offsets, sizes, and hashes before extraction. - Boot and Update Chain Tracing: Follow control flow from bootloader to kernel to init to services, or from update package to verifier to installer, tracking which credentials and configs each stage consumes. - Decisive Path Reduction: Reduce the analysis to the smallest chain from image boundary to service exposure, auth bypass, credential recovery, or flag artifact. - Use Case: Given a CTF firmware image, map its partition table, extract the rootfs, trace the init scripts to a debug service, and recover the credentials that service consumes. ## Quick Start After $ctf-sandbox-orchestrator is active, use $competition-firmware-layout to map this firmware image, extract its partitions, trace the boot chain, and recover the decisive secret.
