AI prompts edge toward real-world browser ransomware, researchers warn
Security researchers at Check Point found an AI-generated DeepSeek sample that could be turned into a fully functional browser-only ransomware with minimal effort, using the browser’s File System Access API to access local files via a web app. The proof-of-concept, InfernoGrabber 9000, targets Android and bundles a toolkit for data theft, encryption, and a ransom overlay, though the current code was incomplete. Experts say the model could assemble the required components inside a front-end, meaning AI-assisted prompts could yield near-ready browser ransomware, even as the browser sandbox blocks many actions. This underscores growing AI-enabled threat potential for end-user devices.
