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.

As usual, I use my open source Vulristics project to analyse and prioritize vulnerabilities.

Vulristics improvements

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:

  1. For Microsoft generated descriptions, e.g. “Microsoft Excel Remote Code Execution Vulnerability”, vulnerability type and product are now directly parsed out of the description, keyword search is not performed.
  2. I rewrote the generic keyword search based on products.json. I have reduced the use of heavy functions without sacrificing the quality of the detections.

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.
