Case study / Firmware security

Embedded Firmware Analysis and Automation

Static security assessment of router, IP camera, and bare-metal firmware, followed by reusable Bash tooling to reproduce important findings.

Problem

Embedded images often contain credentials, keys, vulnerable components, and insecure boot behavior that are invisible without systematic analysis.

Role

Contributed to manual findings and built a modular Bash triage scanner with dependency verification and pluggable checks.

Findings and Tooling

Credential riskFound hard-coded root credentials and authentication material.

Secrets exposureIdentified embedded private keys and cloud-service tokens.

Component riskFlagged vulnerable BusyBox usage in firmware.

Boot-chain riskIdentified insecure U-Boot behavior allowing unsigned code execution.

AutomationBuilt portable scanner modules to reproduce and triage findings.

This maps directly to vulnerability analysis, embedded system assessment, infrastructure risk discovery, and repeatable security engineering.
