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

CVE-2021-1871 WebKitGTK vulnerabilities
Title: WebKitGTK vulnerabilities
Summary: Several security issues were fixed in WebKitGTK.
A large number of security issues were discovered in the WebKitGTK Web and
JavaScript engines. If a user were tricked into viewing a malicious
website, a remote attacker could exploit a variety of issues related to web
browser security, including cross-site scripting attacks, denial of service
attacks, and arbitrary code execution.
Instructions: This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart any applications
that use WebKitGTK, such as Epiphany, to make all the necessary changes.

# Tracking Candiru’s DevilsTongue Spyware in Multiple Countries
Note: The analysis cut-off date for this report was June 26, 2025
## Executive Summary
Insikt Group identified new infrastructure associated with several clusters linked to the spyware vendor Candiru. This includes both victim-facing components likely used for deploying and controlling Candiru’s DevilsTongue spyware, as well as higher-tier operator infrastructure. DevilsTongue is a sophisticated, modular Windows malware. The clusters vary in design and administration, with some directly managing victim-facing systems, while others use intermediaries or the Tor network. Eight distinct clusters were identified, with five being likely still active, including those linked to Hungary and Saudi Arabia. One cluster tied to Indones
