• Mandiant tracked 55 zero-day vulnerabilities that we judge were exploited in 2022. Although this count is lower than the record-breaking 81 zero-days exploited in 2021, it still represents almost triple the number from 2020.
• Chinese state-sponsored cyber espionage groups exploited more zero-days than other cyber espionage actors in 2022, which is consistent with previous years.
• We identified four zero-day vulnerabilities exploited by financially motivated threat actors. 75% of these instances appear to be linked to ransomware operations.
• Products from Microsoft, Google, and Apple made up the majority of zero-day vulnerabilities in 2022, consistent with previous years. The most exploited product types were operating systems (OS) (19), followed by browsers (11), security, IT, and network management products (10), and mobile OS (6).

Besides the Samsung Exynos modem issue, Android 13 QPR2 with the March 2023 security update fixes a vulnerability with the Pixel’s Markup screenshot tool.

Dubbed “aCropalypse,” Simon Aarons identified and reported this vulnerability (CVE-2023-21036) to Google in early January, with the initial proof-of-concept exploit developed by David Buchanan:

Screenshots cropped using the built-in “Markup” app on Google Pixel devices may be retroactively un-cropped and un-redacted under many circumstances.

In late 2022 and early 2023, Project Zero reported eighteen 0-day vulnerabilities in Exynos Modems produced by Samsung Semiconductor. The four most severe of these eighteen vulnerabilities (CVE-2023-24033 and three other vulnerabilities that have yet to be assigned CVE-IDs) allowed for Internet-to-baseband remote code execution. Tests conducted by Project Zero confirm that those four vulnerabilities allow an attacker to remotely compromise a phone at the baseband level with no user interaction, and require only that the attacker know the victim's phone number. With limited additional research and development, we believe that skilled attackers would be able to quickly create an operational exploit to compromise affected devices silently and remotely.
