Researchers Craft Billion-User Chrome Exploit in Six Days A team of four researchers used OpenAI's GPT-5.6 Sol model to chain three zero-day Chrome vulnerabilities into a working exploit in six days, earning a $250,000 bounty from Google. The result demonstrates that a publicly available AI model can compress vulnerability research timelines for a major browser target. In just six days, a team of four researchers harnessed the power of a publicly available AI model to craft a Chrome exploit that earned them a whopping $250,000 bounty from Google. With the help of OpenAI's GPT-5.6 Sol model, they chained together three zero-day Chrome vulnerabilities, proving that innovation and speed can pay off big time.
