Google's Surge in Chrome Vulnerability Discoveries Likely Driven by AI

Chrome security advisories issued by Google reported a small number of vulnerabilities in late March and early April, then increased to 16 on April 15 and 21 on April 28. The count rose further to 100 in an advisory published May 5, with more than 70 vulnerabilities patched across the two most recent Chrome releases found internally. Google did not explicitly state that AI discovered the vulnerabilities, but the timing and related statements suggest AI involvement. Google previously lowered Chrome bug bounties and credited AI and automation for moving at an unprecedented rate and remediating risks more effectively. Google also said AI advancements make it easier to explain root causes, propose fixes, and find variants. Other organizations reported similar surges using AI tools, including Mozilla with Claude Mythos, and Microsoft and Palo Alto Networks using AI vulnerability discovery tools.

"The number of Chrome vulnerabilities discovered by Google has surged over the past month, likely driven by the company's use of AI. Chrome security advisories published by Google in late March and early April mentioned a handful of vulnerabilities "reported by Google", but the number increased to 16 for the Chrome update released on April 15 and 21 for the update issued on April 28. The number of vulnerabilities found by Google surged to 100 in the advisory published on May 5. More than 70 vulnerabilities patched in the two most recent Chrome releases were found internally by the tech giant."

"While Google has not specifically said the vulnerabilities were discovered using AI, the timing of the surge and other aspects suggest that artificial intelligence is responsible. When it recently announced lowering Chrome bug bounties, Google noted that AI and automation have been helping its teams move "at an unprecedented rate - remediating risks more effectively than ever before." "The latest advancements in AI from Google and the broader industry have made it significantly easier to take a test case and explain the root cause, propose a suitable fix, and to find variants of known problems," Google said."

"Other major organizations have also reported surges in vulnerability discovery thanks to the use of third-party or internal AI tools. Mozilla, for instance, found over 270 Firefox vulnerabilities with the aid of Anthropic's new Claude Mythos model. Microsoft and Palo Alto Networks have also found many vulnerabilities in their products using advanced AI vulnerability discovery tools. It's unclear which AI model may have been used by Google to discover the Chrome vulnerabilities. Google is one of roughly 50 organizations granted access to Claude Mythos."

"Google has also been working on its own AI-powered vulnerability discovery tools, such as Big Sleep and CodeMender. "CodeMender is an AI code securi"
