Claude Opus wrote a Chrome exploit for $2,283

A security researcher used Anthropic's Opus 4.6 model to generate a full exploit chain targeting the V8 JavaScript engine in Chrome 138 (bundled in older Discord/Electron builds), demonstrating model-assisted development of working exploit code (proof: ‘popped calc’). The article highlights that such AI-assisted exploit generation reduces time and cost to create weaponized exploits, shrinking the patch window for Electron-based apps and raising the risk that attackers with API access could rapidly weaponize public vulnerability details.
