Hello 0-Days, My Old Friend: A 2024 Zero-Day Exploitation Analysis


Google Threat Intelligence Group (GTIG) tracked 75 zero-day vulnerabilities exploited in the wild in 2024, a decrease from the number we identified in 2023 (98 vulnerabilities), but still an increase from 2022 (63 vulnerabilities).
