Capital One "VulnHunter" - an open harness for vulnerability discovery Cool to see more and more OSS in the security domain. You can clone it from GitHub and run it now. Significant adds in three key areas:

* Falsification Engine: After finding a potential vulnerability, VulnHunter runs a structured reasoning workflow specifically designed to disprove its own argument. It searches for flawed assumptions, logic gaps, or security controls that would block the attack. * Evidence-Backed Remediation: When a defect survives the falsification engine, VulnHunter maps the exact exploit path and generates focused, targeted code changes for review. * Attacker-First Forward Analysis: VulnHunter flips the "sink-first" security model to reduce false positives by simulating a bad actor's exact journey. It begins at potential attacker-accessible entry points (APIs, network messages, file uploads) and reasons forward to evaluate whether an attacker can truly break through. https://github.com/capitalone/vulnhunter
