While this number falls short of the record high set in 2021, standing at 106, concerns are rising within the cybersecurity community.

Collaborating for the first time, Google’s Threat Analysis Group (TAG) and Mandiant jointly released the “We’re All in this Together: A Year in Review of Zero-Days Exploited In-the-Wild in 2023” report.

This comprehensive review not only examines the landscape of zero-day exploits but also offers actionable insights and recommendations for enhancing digital security. It also underscores the significance of vendor investments in combating zero-day threats.

Major players like Apple, Google, and Microsoft have made substantial strides in fortifying their platforms against exploitation. Notably, Google’s MiraclePtr and Apple’s Lockdown mode for iOS stand out as effective measures in thwarting exploit attempts.

Despite advancements in end-user platforms, attackers are shifting focus towards third-party components and libraries, exploiting vulnerabilities that can impact multiple products.

Commercial surveillance vendors (CSVs) emerged as prominent actors in browser and mobile device exploitation, responsible for 75 percent of known zero-day exploits targeting Google products and Android ecosystem devices.

Additionally, government-backed exploitation, notably by the People’s Republic of China (PRC), continues to pose significant threats, with cyber espionage groups exploiting 12 zero-day vulnerabilities in 2023.

The report outlines several recommendations for individuals and organizations to bolster their security posture, emphasizing transparency, prioritization of threats, and the establishment of robust security foundations.

High-risk users are advised to enable advanced security features such as Lockdown mode for iOS and Memory Tagging Extensions (MTE) for Pixel 8 users.
