Explore a novel attack vector in open-source projects using GitHub Actions in this 19-minute conference talk from BSidesLV. Discover how leaked access tokens hidden within build artifacts can be exploited to gain control over open-source projects. Learn about the challenges of racing against time to utilize ephemeral tokens before they expire, and see real-world examples of breached popular open-source projects and those maintained by high-profile organizations. Gain insights into unearthing sensitive data in build artifacts, crafting high-speed exploits, and executing swift attacks using these techniques.
