New Study Shows GPT-5.2 Can Reliably Develop Zero-Day Exploits at Scale

A groundbreaking experiment has revealed that advanced language models can now create working exploits for previously unknown security vulnerabilities. Security researcher Sean Heelan recently tested two sophisticated systems built on GPT-5.2 and Opus 4.5, challenging them to develop exploits for a zero-day flaw in the QuickJS Javascript interpreter. The results point to a significant shift […]
