Google recently revealed a worrying statistic: in 2023, 97 zero-day vulnerabilities were exploited, marking an increase of more than 50% compared to the previous year, when 62 such vulnerabilities were recorded. This alarming growth underscores an ever-changing security landscape and the imperative need for vigilance on the part of users and developers.
Google's Threat Analysis Group (TAG), along with Mandiant, conducted an in-depth analysis of these zero-day flaws that were disclosed over the past year. Of the 58 vulnerabilities for which the motivation of the attackers could be determined, espionage was the main trigger for 48 of them.
Google claims that these zero-day vulnerabilities are unknown flaws until they are exploited, but they pose a major threat because they give hackers a window of opportunity to attack before IT teams can intervene.
Google reveals that the year 2023 has brought a particular focus on consumer-oriented products, including smartphones, operating systems, web browsers and various applications. Google identified a total of 61 zero-day vulnerabilities that targeted these domains, highlighting increased interest from cybercriminals.

Android, it was affected by nine exploited vulnerabilities, up significantly from just three recorded in 2022. iOS also reported a similar number of nine zero-day vulnerabilities, compared to four the previous year. In addition, Google Chrome was targeted by eight such vulnerabilities, while Safari recorded 11.
Windows remains at the top of the list with 17 exploited zero-day vulnerabilities, highlighting a worrying trend among popular operating systems and applications. Geographic analysis of exploits reveals that state-sponsored threat actors in China, Russia, North Korea and Belarus were particularly active, with 12 of the zero-day vulnerabilities attributed to China.
In total, state-sponsored espionage accounted for 41,4% of zero-day exploits in 2023, reflecting a strategic use of these vulnerabilities in surveillance and intelligence-gathering operations. However, significant investments in mitigating vulnerabilities, particularly in browsers and operating systems, have begun to limit attackers' ability to achieve their goals.
Companies like Apple, Google, and Microsoft have devoted considerable resources to countering these threats, affecting the types and number of zero-day vulnerabilities available to attackers. Despite the lower number of zero-day vulnerabilities disclosed in 2023 compared to 2021, experts suggest that the rate of discovery and exploitation of these vulnerabilities is likely to remain high.
This underscores the importance of a proactive approach to cybersecurity as cybercriminals continue to refine their attack methods. Users and developers must remain vigilant by constantly updating software and implementing robust security practices to protect against evolving threats.
