Over four months, Musiorun developed and maintained security testing infrastructure across google/security-testbeds and google/tsunami-security-scanner-plugins. They built Dockerized environments and automated workflows for vulnerability detection, including Locust-based performance testing and a Tsunami plugin for PyZMQ RCE. Using Python, Java, and Docker, Musiorun implemented exploit scripts and detector plugins for vulnerabilities such as CVE-2025-32433 in Erlang/OTP SSH, enabling reproducible testing and streamlined demonstrations. Their work included codebase maintenance, metadata updates, and documentation improvements, enhancing maintainability and test robustness. The depth of engineering addressed both feature delivery and long-term code quality, supporting ongoing security research and onboarding.
