A review of zero-day in-the-wild exploits in 2023

Google’s Threat Analysis Group (TAG) and Mandiant released a joint 2023 review reporting 97 zero-day vulnerabilities exploited in the wild—an increase of over 50% from 2022—covering both consumer platforms (mobile, OS, browsers, apps) and enterprise technologies (security software, appliances). The report combines telemetry and analysis to assess the scale and trends of active zero-day exploitation and offers guidance for improving security across the ecosystem.
