Wireless and embedded systems often expose limited interfaces, weak update paths, insecure default settings, and long operational lifetimes. Their security depends on physical access assumptions, radio proximity, firmware integrity, and supply-chain trust.

The security of embedded devices often hinges on whether the boot chain verifies signatures, whether update packages are authenticated, and whether secrets are protected at rest. Once physical or local access is assumed, many devices reveal powerful diagnostic or recovery paths that must be evaluated carefully.

Embedded assessments may intersect with physical safety, industrial control constraints, and service continuity requirements. The ethical hacker must avoid actions that could disrupt equipment, alter safety states, or create irreversible field conditions.
