October 2023: back to Positive Technologies, Vulristics updates, Linux Patch Wednesday, Microsoft Patch Tuesday, PhysTech VM lecture. Hello everyone! October was an interesting and busy month for me. I started a new job, worked on my open source Vulristics project, and analyzed vulnerabilities using it. Especially Linux vulnerabilities as part of my new Linux Patch Wednesday project. And, of course, analyzed Microsoft Patch Tuesday as well. In addition, at the end of October I was a guest lecturer at MIPT/PhysTech university. But first thing first.

August 2023: GitHub PoCs, Vulristics, Qualys First-Party, Tenable ExposureAI, SC Awards and Rapid7, Anglo-Saxon list, MS Patch Tuesday, WinRAR, Juniper

August 2023: GitHub PoCs, Vulristics, Qualys First-Party, Tenable ExposureAI, SC Awards and Rapid7, Anglo-Saxon list, MS Patch Tuesday, WinRAR, Juniper. Hello everyone! This month I decided NOT to make an episode completely dedicated to Microsoft Patch Tuesday. Instead, this episode will be an answer to the question of how my Vulnerability Management month went. A retrospection of some kind.

Vulristics News: EPSS v3 Support, Integration into Cloud Advisor. Hello everyone! This episode will focus on the news from my open source Vulristics project for vulnerability analysis and prioritization.

EPSS v3

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.

Microsoft Patch Tuesday April 2022 and custom CVE comments sources in Vulristics. Hello everyone! This episode will be about Microsoft Patch Tuesday for April 2022 and new improvements in my Vulristics project. I decided to add more comment sources. Because it’s not just Tenable, Qualys, Rapid7 and ZDI make Microsoft Patch Tuesday reviews, but also other security companies and bloggers.

Leave a reply

Vulristics: Microsoft Patch Tuesdays Q1 2021. Hello everyone! It has been 3 months since my last review of Microsoft vulnerabilities for Q4 2020. In this episode I want to review the Microsoft vulnerabilities for the first quarter of 2021. There will be 4 parts: January, February, March and the vulnerabilities that were released between the Patch Tuesdays.

I will be using the reports that I created with my Vulristics tool. This time I’ll try to make the episodes shorter. I will describe only the most critical vulnerabilities. Links to the full reports are at the bottom of the blog post.

Microsoft Patch Tuesday August 2020: vulnerabilities with Detected Exploitation, useful for phishing and others. This time I would like to review not only the vulnerabilities that were published in the last August Microsoft Patch Tuesday, but also the CVEs that were published on other, not Patch Tuesday, days. Of course, if there are any.

But let’s start with the vulnerabilities that were presented on MS Patch Tuesday on August 11th. There were 120 vulnerabilities: 17 of them are Critical and 103 Important. My vulristics script could not find public exploits for these vulnerabilities on Vulners.com.

Barapass update

I recently released an update to my password manager barapass. BTW, it seems to be my only pet project at the MVP stage, which I use every day.

What’s new:

  1. Now I am sure that it works on Windows 10 without WSL. And you can run it beautifully even with the icon. ? Read more about installation in Windows in this file.
  2. Not only “copy the next value to the clipboard” (or “revolver mode” ) is now possible in the search results section. You can also get the previous value or copy the same value one again if it was somehow erased in the clipboard. Previously, I had to retype the search request each time to do this, and it was quite annoying. By the way, I unexpectedly discovered that the user input history inside the application magically works in the Windows shell (using up and down arrows) without any additional coding. On Linux it does not.
  3. You can set a startup command, for example, to decrypt the container.
  4. The startup command and quick (favorite) commands are now in settings.json and not hard-coded.
  5. settings.json, container files and decrypted files are now in “files” directory. It became more convenient to update barapass, just change the scripts in the root directory and that’s it. I divided the scripts into several files, now it should be more clear how it works.

So, if you need a minimalistic console password manager in which you can easily use any encryption you like – welcome! You can read more about barapass in my previous post.
