OpenHack: Open-source AI-powered vulnerability research

Source-guided vulnerability research increasingly leans on coding harnesses such as Claude Code, Codex, and Cursor to drive agent-based reviews of application code. A new MIT-licensed project from the Dutch security firm Hadrian, called OpenHack, packages that approach into a file-based workspace that any of those harnesses can run. OpenHack is a set of agents and tools that mimics how Hadrian’s research team performs automated vulnerability research.
