OpenBullet is a legitimate, open-source web testing suite originally designed for security professionals to perform stress-testing and fuzzing on web applications. However, like many powerful tools, it has been weaponized by threat actors for credential stuffing attacks .

In the right hands, OpenBullet checks if a website’s login forms are resilient to brute-force attempts. In the wrong hands, it automates the process of taking millions of username/password pairs leaked from one service (e.g., LinkedIn, Adobe) and testing them against another (e.g., PayPal, Netflix, banking portals). openbullet 1.4.4 anomaly download
