CVE-2016-5128 [HIGH] 2022 0-day In-the-Wild Exploitation…so far - Project Zero
Posted by Maddie Stone, Google Project Zero
This blog post is an overview of a talk, “ 0-day In-the-Wild Exploitation in 2022…so far”, that I gave at the FIRST conference in June 2022. The slides are available here.
For the last three years, we’ve published annual year-in-review reports of 0-days found exploited in the wild. The most recent of these reports is the 2021 Year in Review report, which we published just a few months ago in April. While we plan to stick with that annual cadence, we’re publishing a little bonus report today looking at the in-the-wild 0-days detected and disclosed in the first half of 2022.
As of June 15, 2022, there have been 18 0-days detected and disclosed as exploited in-the-wild in 2022. When we analyzed those 0-days, we found that at least nin

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-2022-21882 [HIGH] Inside Win32k Exploitation: Background on Implementations of Win32k and Exploitation Methodologies
## Executive Summary
In late January 2022, several reports on social media indicated that a new Microsoft Windows privilege escalation vulnerability (CVE-2022-21882) was being exploited in the wild. These reports prompted us to do an analysis of CVE-2022-21882, which turned out to be a vulnerability in the Win32k.sys user-mode callback function xxxClientAllocWindowClassExtraBytes.
In 2021, a very similar vulnerability (CVE-2021-1732) was reported to – and patched by – Microsoft. We decided to take a closer look at both vulnerabilities to better understand the code involved in each. In our initial analysis we wanted to determine why the patch for CVE-2021-1732 was not sufficient to prevent CVE-2022-21882.

BlueSky ransomware is an emerging threat that researchers have been paying increasing attention to since its initial discovery in late June 2022. The ransomware has been observed being spread via trojanized downloads from questionable websites as well as in phishing emails.
Although infections at this time remain low, the ransomware’s characteristics, described below, suggest it has been carefully developed for a sustained campaign. In this post, we cover the latest intelligence on BlueSky ransomware to help security teams defend against this developing threat.

Wiz supports the new CISA Known Exploited Vulnerabilities (KEV) Catalog as a source of exploit intelligence to vulnerability findings, on top of other sources. The new CISA binding directive helps enterprises to reduce cyber incidents by prioritizing the mitigation of vulnerabilities known to be actively exploited in order to improve the vulnerability management process. Vulnerabilities listed in the KEV catalog are less than 1% of the vulnerability findings in the cloud. Combined with the unique capabilities offered by Wiz to discover the toxic combinations that represent a real threat in your cloud environment, you can now better prioritize and focus on the risks that matter the most.
