Things I Learned (TIL) FOR508 Review 2024

How Not… talk: slides and links Herein are some books, articles, and people that we read, skimmed, or thought fondly of while preparing the “How Not to Have a Bad Time with Risky Data” talk seen at B-Sides Atlanta 2024

TIL DFIR Summit 2024 online

Here are some thoughts and links about some of the things I’m thinking about for professional development and education for the year. Update 1 in early July with some details and “how it’s going”. Update 2 in early Oct with more details and “how it’s going”.

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:

People have different needs and priorities, so getting more information helps everyone make better decisions. Hope this helps!

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.

How can we see port proxy configurations in DFIR?

This morning with much coffee I’m working between email to practice netcat between hosts for GSE, PWK, and generally building good character.

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

draft post, needs more links and images

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.
