For the first time, Google says it has spotted and stopped a zero-day exploit developed with AI. According to a report from Google Threat Intelligence Group (GTIG), “prominent cyber crime threat actors” were planning to use the vulnerability for a “mass exploitation event” that would have allowed them to bypass two-factor authentication on an unnamed “open-source, web-based system administration tool.”
Google’s researchers found hints in the Python script used for the exploit that indicated help from AI, like a “hallucinated CVSS score” and “structured, textbook” formatting consistent with LLM training data. The exploit takes advantage of “a high-level semantic logic flaw where the developer hardcoded a trust assumption” in the platform’s 2FA system. This follows weeks of hand-wringing over the capabilities of cybersecurity-focused AI models like Anthropic’s Mythos and a recently disclosed Linux vulnerability that was discovered with AI assistance.
