The More You Know, The More You Know You Don’t Know
A Year in Review of 0-days Used In-the-Wild in 2021
Posted by Maddie Stone, Google Project Zero
This is our third annual year in review of 0-days exploited in-the-wild [2020, 2019]. Each year we’ve looked back at all of the detected and disclosed in-the-wild 0-days as a group and synthesized what we think the trends and takeaways are. The goal of this report is not to detail each individual exploit, but instead to analyze the exploits from the year as a group, looking for trends, gaps, lessons learned, successes, etc. If you’re interested in the analysis of individual exploits, please check out our root cause analysis repository.
We perform and share this analysis in order to make 0-day hard. We want it to be more costly, more resource intensive, and overall more difficult for attackers to use 0-day capabilities. 2021 highlighted just how important it is to stay relentless in our pursuit to make it harder for attackers to exploit users with 0-days. We heard over and over and over about how governments were targeting journalists, minoritized populations, politicians, human rights defenders, and even security researchers around the world. The decisions we make in the security and tech communities can have real impacts on society and our fellow humans’ lives.
We’ll provide our evidence and process for our conclusions in the body of this post, and then wrap it all up with our thoughts on next steps and hopes for 2022 in the conclusion. If digging into the bits and bytes is not your thing, then feel free to just check-out the Executive Summary and Conclusion.
Executive Summary
2021 included the detection and disclosure of 58 in-the-wild 0-days, the most ever recorded since Project Zero began tracking in mid-2014. That’s more than double the previous maximum of 28 detected in 2015 and especially stark when you consider that there were only 25 detected in 2020. We’ve tracked publicly known in-the-wild 0-day exploits in this spreadsheet since mid-2014.
While we often talk about the number of 0-day exploits used in-the-wild, what we’re actually discussing is the number of 0-day exploits detected and disclosed as in-the-wild. And that leads into our first conclusion: we believe the large uptick in in-the-wild 0-days in 2021 is due to increased detection and disclosure of these 0-days, rather than simply increased usage of 0-day exploits. ...
