## Summary

Hardware hacking has traditionally been a tedious process demanding deep expertise, patience, and repetitive manual execution. To eliminate this friction, researchers are increasingly leveraging AI—specifically Claude orchestrated via the Model Context Protocol (MCP)—to autonomously interface with physical IoT targets. By transitioning from theoretical software exploits to physical hardware access, these AI agents can independently probe debug ports, extract firmware secrets, and intercept cloud traffic with nearly zero human intervention.

The practical execution is demonstrated against a Gosund SP112 V2 Wi-Fi smart plug running a BK7231N chip. Empowered by an SQLite vector database for local memory, the agent recalls past attack histories to formulate an engagement plan before ever touching the physical hardware. While the device's companion app successfully blocked Man-in-the-Middle attacks via robust TLS pinning, the agent pivoted laterally to the hardware itself. Without needing authentication, the agent exploited the UART debug interface to request the chip's flash encryption key in plain text. This access allowed the agent to decrypt the entire 2MB flash dump, instantly exposing cloud impersonation tokens and local Wi-Fi passwords.

This autonomous workflow indicates a paradigm shift where specialized knowledge and physical effort are no longer reliable barriers to entry in hardware security. The AI actively documents constraints, learns from failed radio and network approaches, and iteratively updates its local knowledge base for future engagements. Critically, the exploration revealed that standard factory resets fail to clear internal key-value stores, meaning seemingly wiped and discarded smart devices remain fully intact credential bundles available to anyone leveraging off-the-shelf AI tooling.
