AI accelerates n-day attacks, as flaw disclosures and exploits double

Summary

Google's Threat Intelligence Group (GTIG) reports that attackers exploited 141 flaws between January and August 2026, more than the 127 exploited in all of 2025. The report links the shift toward n-day weaponization to AI tools that help attackers analyze patches, disclosures and proof-of-concept code. The source notes that the exploited share of disclosed flaws remains small at 0.23%.
