OpenHack: Open-source AI

Feeds2.Feedburner •Sinisa Markovic • May 25, 2026

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. The workflow runs inside a coding harness or a … More →

Hadrian Launches OpenHack for AI Vulnerability Research Hadrian has open-sourced OpenHack, a file-based workflow for AI-assisted source-code vulnerability research, announced on May 20, 2026. This MIT-licensed tool integrates with Claude Code, Codex, and Cursor, enabling automated vulnerability assessments. OpenHack employs a scenario-first review model and independent triage to enhance accuracy and reduce false findings. The methodology was previously used to identify critical vulnerabilities in open-source software utilized by Dutch government agencies. The system maintains a durable state in plain files and includes a registry of expert families aligned with OWASP and MITRE standards. OpenHack aims to democratize advanced vulnerability research methodologies, making them accessible to a broader audience. The tool's design focuses on reproducibility and auditability, addressing common issues in model-driven code reviews. 2 sources 25
