notes on DFIR practice and practice
What would make up the perfect cybersecurity threat intelligence (CTI) report to receive, ingest, automate around? Honestly, even any three of these things makes for a great report. More context and detail are better, if the report author / information sharing organisation can support it.
My recommendations to new folks, mentees, and several Lyft drivers in TL;DR or perhaps BLUF:
Collecting a number of questions that might be informative to ask in job interviews, for practice and mentoring usage. You probably can’t/shouldn’t ask all of these, might not get an answer, and “No” isn’t bad. Deliberately excluded are most compensation and benefits questions which you should definitely ask about. People have different needs and priorities, so getting more information helps everyone make better decisions. Hope this helps!
programming experience helpful, but not required

Nearly half-way through a busy year I think I know what I’m working on … especially after dropping out of college again after trying it again for a couple years. I’m dividing up my time and attention mostly between the two skillsets that I’ve used so far and see myself continuing to use at $dayjob and beyond.
Herein are a few notes on my prepping to renew my GSE as traditionally made and posted before taking the exam. I’ll be taking the renewal exam shortly and won’t be able to comment about it.

A question came in via mail this week: “I see that there is Windows-based security distribution flare-vm. I am wondering the difference between REMnux and flare-vm.

Some words about hunting including some perspectives from different sources

Some fairly detailed notes on the classes I taught, took, conferences I attended, fees, and other professional development and education expenses in 2016, for discussion
After looking at the tables with the MAC address for awhile I looked up the OUI online and substituted them in, hoping to catch something I’d missed. Indeed there was a third MAC from a third manufacturer in the discussion. All three OEMs make network gear as well as endpoint systems.

Emily sent me so many copies of this executable in the last couple days that I decided to take a look:
As I’ve mentioned before one of the things I’m self-studying these days is file analysis. The chosen text is the most excellent Practical Malware Analysis (red with the alien autopsy cover). The authors include lab exercises to demonstrate the analysis techniques from each chapter and they are freely available, so buy a couple copies of the book, such as from the publisher’s site.
