Google has seen a dramatic surge in Chrome vulnerability discoveries, jumping from handfuls of bugs in early April to over 100 in early May, with strong indications that AI tools are behind the spike. While Google hasn't explicitly confirmed AI's role, the timing aligns with their recent statements about AI helping security teams remediate risks at unprecedented rates, and they've been developing AI-powered tools like CodeMender and Big Sleep for vulnerability detection. This mirrors similar breakthroughs at Mozilla, Microsoft, and Palo Alto Networks, which have also reported major increases in bugs discovered using AI-assisted scanning.
