Detection & IOCsextracted from sources · hover to see the quote
- →CVE-2021-30563 is a Type Confusion vulnerability in the V8 JavaScript engine; exploitation occurs via a crafted HTML page delivered remotely — monitor for suspicious or anomalous HTML/JS content triggering V8 type confusion conditions in Chrome versions prior to 91.0.4472.164 ↗
- →This vulnerability was exploited in the wild — treat any unpatched Chrome/Edge/Opera (Chromium-based) instance below the fixed version as actively at risk; prioritize detection of exploitation attempts against Chromium V8 across all Chromium-based browsers ↗
- →Google issued the patch as a zero-day on or around July 15–16 2021; any Chrome telemetry showing the browser version below 91.0.4472.164 after this date indicates an unpatched, exploitable instance ↗
- ·The vulnerability affects all Chromium-based browsers (Chrome, Microsoft Edge, Opera, etc.), not just Google Chrome — detection and patching scope must cover all Chromium consumers ↗
- ·On Debian, the fix was not shipped until Chromium 93.0.4577.82-1 across all supported releases (bookworm, bullseye, sid, trixie, forky) — systems running Debian-packaged Chromium remained vulnerable through the entire 91.x and 92.x series ↗

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
