Written by: Casey Charrier, James Sadowski, Zander Work, Clement Lecigne, Benoît Sevens, Fred Plan Executive Summary Google Threat Intelligence Group (GTIG) tracked 90 zero-day vulnerabilities exploited in-the-wild in 2025. Although that volume of zero-days is lower than the record high observed in 2023 (100), it is higher than 2024’s count (78) and remained within the 60–100 range established over the previous four years, indicating a trend toward stabilization at these levels.
