Getting started with Mantis, our open-source bug finding-and-fixing harness (Google Cloud)
blog post · Story page
Google open-sources Mantis, a harness that finds, triages, reproduces, and patches software vulnerabilities using critic agents and sandboxed reproduction.
In plain words
- Google released Mantis, free software that finds, checks, recreates, and fixes security flaws.
- One artificial intelligence system proposes flaws, while others question and review its findings.
- It recreates each suspected flaw in an isolated test environment before treating the report as real.
- It reads past security fixes and builds layered notes about the software's structure and possible threats.
- For software defenders, this could reduce false alarms and help them fix real weaknesses faster.
