Hello everyone! On the last day of September, I decided to record another retrospective episode on how my Vulnerability Management month went.

September was quite a busy month for me.
I participated in two educational activities. The first one is an on-line cyber security course for my alma mater, Bauman Moscow State Technical University.
Continue readingHello 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.

This month I made some improvements to my Vulristics vulnerability prioritization tool. These changes relate to the use of exploit data on Github. We all know that exploits are often posted on GitHub. But how adequate is this source in order to evaluate the exploitability?
Continue readingHello everyone! This episode will be about Microsoft Patch Tuesday for July 2023, including vulnerabilities that were added between June and July Patch Tuesdays.

As usual, I use my open source Vulristics project to analyse and prioritize vulnerabilities.
I optimized the detection of the vulnerable product and the type of vulnerability based on the description. Now processing already downloaded data (with option --rewrite-flag "False") takes a few seconds. For example, only ~3 seconds for 100 MS Patch Tuesday vulnerabilities . It used to take a few minutes.
What I’ve done:
Hello everyone! This episode will be about Microsoft Patch Tuesday for June 2023, including vulnerabilities that were added between May and June 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. This time there were only 3 vulnerabilities used in attacks or with a public exploit. And only one of them is more or less relevant.

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! 😄

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.
