Detection & IOCsextracted from sources · hover to see the quote
- →Vulnerability exists in Google Chrome versions prior to 93.0.4577.82; presence of older versions indicates unpatched exposure to this use-after-free sandbox escape ↗
- →Exploitation requires a compromised renderer process as a prerequisite; monitor for renderer process anomalies combined with Indexed DB API activity as a chained exploitation indicator ↗
- →Vulnerability affects multiple Chromium-based browsers beyond Chrome, including Microsoft Edge and Opera; broaden detection scope accordingly ↗
- →CVE-2021-30633 is tracked in CISA KEV catalog with a remediation due date of 2021-11-17, indicating confirmed in-the-wild exploitation; prioritize detection and patching ↗
- →Chromium bug tracker ID 1247766 is associated with this CVE; can be used to cross-reference patch commits and diff analysis for signature development ↗
- ·Exploitation requires a pre-compromised renderer process; this is a second-stage sandbox escape, not a direct initial-access vector ↗

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.

A Relevance Model for Threat-Centric Ranking of Cybersecurity Vulnerabilities
## Abstract
The relentless process of tracking and remediating vulnerabilities is a top concern for cybersecurity professionals. The key challenge is trying to identify a remediation scheme specific to in-house, organizational objectives. Without a strategy, the result is a patchwork of fixes applied to a tide of vulnerabilities, any one of which could be the point of failure in an otherwise formidable defense. Given that few vulnerabilities are a focus of real-world attacks, a practical remediation strategy is to identify vulnerabilities likely to be exploited and focus efforts towards remediating those vulnerabilities first. The goal of this research is to demonstrate that aggregating and synthesizing readily accessible, public data sources to provide personalized, automated recommendat
