This isn’t a rant, far from it but I’ve been working on this for over a week now and some major questions are sprining to mind with regard to how the IOCs and detection details released may have hindered response efforts. These vulnerabilities were known about since at least December 2020, there were months to get detection intel and scripts/tools ready for people (that’s if you don’t question why did it take so long).

Windows update sometimes has issues (does not all software!) and it is sometimes that we need to help it along the way, so let’s get too it! Read more “Field Notes – Just Patch”
