Rockstar🎓
Top SchoolJonathan Leitschuh is a software engineer and prolific open source security researcher with 12 years of experience, credited on 40+ CVEs and known for the widely covered 2019 Zoom macOS vulnerability disclosure. He specializes in large-scale OSS vulnerability hunting and automated remediation using tools like CodeQL, GitHub Code Search, and OpenRewrite, and has driven fixes across critical Java ecosystem projects such as Gradle, Maven, and SnakeYAML. Jonathan blends deep build-tooling and JVM expertise with practical automation—authoring Gradle plugins and mass-refactor recipes—to scale disclosure and fixes through bulk pull requests. He’s an inaugural Dan Kaminsky Fellow who has presented at DEF CON, Black Hat, and GitHub Universe, and has applied his research at organizations including Chainguard, the Linux Foundation, HUMAN, and Gradle. Based in Boston, he pairs hands-on engineering (from robotic vision to CI/test frameworks) with an advocacy focus on making open source safer at scale.
