Hello everyone! This episode will be about Microsoft Patch Tuesday for May 2023, including vulnerabilities that were added between April and May Patch Tuesdays.
As usual, I use my open source Vulristics project to analyse and prioritize vulnerabilities. I took the comments about the vulnerabilities from the Qualys, Tenable, Rapid7, ZDI Patch Tuesday reviews.
It’s been a long time since we’ve had such tiny Patch Tuesday. 57 CVEs, including CVEs appeared during the month. And only 38 without them! 😄
Hello everyone! This episode will be about Microsoft Patch Tuesday for April 2023, including vulnerabilities that were added between March and April Patch Tuesdays.
As usual, I use my open source Vulristics project to analyse and prioritize vulnerabilities. I took the comments about the vulnerabilities from the Qualys, Tenable, Rapid7, ZDI Patch Tuesday reviews. And this is the first Patch Tuesday report since I added EPSS support to Vulristics. 😉
Compared to March, Microsoft Patch Tuesday for April 2023 is kind of weak. 🙄
The third iteration of the Exploit Prediction Scoring System (EPSS) was released in March. It is stated that EPSS has become 82% better.There is a pretty cool and detailed article about the changes. For example, EPSS Team began to analyze not 16 parameters of vulnerabilities, but 1164. I have a suspicion that most of these properties are vendor labels, as in the table.
But trying to figure out how it actually works is not very promising. After all, this is the output of some neural network. So there is no algorithm there. In terms of complexity and incomprehensibility, this is already similar to Tenable VPR. But the fact that EPSS is available for free redeems everything. 😇 By the way, the article mentions Tenable VPR and other commercial scores and criticizes them for their proprietary nature, public inaccessibility, and the fact that these scores are partly based on expert opinion, and not just on data.
Hello everyone! This episode will be about Microsoft Patch Tuesday for March 2023, including vulnerabilities that were added between February and March Patch Tuesdays.

Microsoft Patch Tuesday for March 2023 was quite refreshing. 😈
Hello everyone! This episode will be about Microsoft Patch Tuesday for February 2023, including vulnerabilities that were added between January and February Patch Tuesdays.
This month I decided to change the format a bit. Now I share my impression of Microsoft Patch Tuesday on the same Patch Tuesday day in my main telegram channel avleonovcom and my second russian telegram channel avleonovrus. You can also find a draft of the Vulristics report there. So please subscribe. And the full blog post/video is published with a delay. And, in fact, this is it.

Hello everyone! This episode will be about Microsoft Patch Tuesday for January 2023, including vulnerabilities that were added between December and January Patch Tuesdays.
As usual, I use my open source Vulristics project to analyse and prioritize vulnerabilities. I took the comments about the vulnerabilities from the Qualys, Nessus, Rapid7 and ZDI Patch Tuesday reviews.
Hello everyone! As we saw in the last episode, the results of vulnerability detection for one host produced by two different APIs can vary greatly. Therefore, in order to find out the truth, it is necessary to understand what vulnerability data is provided by the Linux distribution vendor and how this data is structured.
Why is it important to do this? Because using data from a Linux distribution vendor, we can ask vulnerability detection API vendors questions: why are you detecting in a different way than described in this data? And then we will understand what caused the difference. And we will either adjust the API for vulnerability detection, or we will adjust the content of the Linux distribution vendor. Either way, it will be a success! In any case, the transparency of the vulnerability detection process will increase.
