Security Testing

Fuzzing is no longer an esoteric research pursuit - it is a mainstream, essential technique for uncovering bugs and vulnerabilities at scale. Its power lies in its automation, its ability to stress test complex software beyond the imagination of its authors, and its proven track record in exposing security-critical flaws. For security researchers, mastering fuzzing is a must. The tooling, techniques, and research continue to evolve - offering ever more effective ways to probe software for weaknesses before adversaries do.

The Bluetooth Hands-Free Profile is a mature, widely deployed protocol underpinning modern mobile and automotive connectivity. Its AT command interface and state-driven design offer flexibility and interoperability, but also expose implementation pitfalls that can affect device security and reliability. Comprehensive, protocol-aware fuzzing and testing - like that delivered by Penzzer - is no longer optional for manufacturers and integrators who care about the security and resilience of their connected devices. As the attack surface for automotive and IoT grows, so too does the need for ongoing, automated security assurance.

MCP servers and streamable-HTTP are changing how modern systems communicate - but with innovation comes new risk. The persistent, multiplexed, and context-rich nature of these protocols exposes critical attack surfaces invisible to traditional security tools. By leveraging protocol-aware fuzzing with tools like Penzzer's MCP Inspector, security researchers can close these gaps, uncover high-impact vulnerabilities, and ensure the next generation of web infrastructure is as secure as it is powerful.
