This post by Jeff (@jeffmakes) was delayed due to interferences with other projects but nevertheless, enjoy!
This year, it was my great honour to design the hardware for the Troopers19 badge.
We wanted to make a wifi-connected MicroPython-powered badge; something that would be fun to take home and hack on. It was a nice opportunity to use a microcontroller platform that I hadn’t tried before. I also used the project as a chance to finally migrate my PCB workflow from Eagle to Kicad. Inevitably it was a painful transition, which resulted in quite some delay to the project as I floundered around in the new tool, but it does mean the design files are in an open format which I hope will benefit the community of Troopers attendees and future badge designers!
This blogpost contains summaries of talks from this year’s TROOPERS19 Active Directory Security Track.
From Workstation to Domain Admin: Why Secure Administration Isn’t Secure and How to Fix It by Sean Metcalf
Active Directory is probably used in almost every corporation today to administer all kinds of Authorization, Authentication and Privileges. This means they are valuable targets for attackers, because once compromised they could do whatever they want. This would be the worst case scenario, right? Therefore securing AD is important and this year TROOPERS19 featured a whole track solely for AD Security.
As promised in my previous post, I am back for an overview of the Troopers19 – Active Directory related talks… Videos have been published and it’s popcorn time… So if you are into stories about Kingdoms and Crown Jewels, grab your loved one [or a drink…] and turn the lights down low, ’cause tonight it’s “Troopers & Chill…”
Sadly, TROOPERS 19 is already over. I had great fun meeting all of you, helping you with your badge problems and seeing others hacking on their badges for example to get custom images on there.
With this year’s badge we wanted to give you something you can reuse after the conference, learn new things new build something on your own.
As promised in our talk Jeff and I would like to give you a short introduction into the badge internals. Along with this post we will release the source code for the badge firmware, the provisioning server and the schematics for the PCB.
When I got home last weekend after an awesome week at WEareTROOPERS, my 5yr old asked me what actually happened in Heidelberg…
I told him we were meeting with some people from all over the world to talk about computer security, and he asked me if it was “to stop the bad guys, like super-heroes?”. So I told him “yes, kind of…”, and he decided he would take his new Troopers T-Shirt to school on Monday to show his classmates. Kids are truly amazing… [<3 <3 <3]
But since you are not a kid anymore, I would like to take the opportunity of this blogpost to go into a bit more details and tell you what really happens at Troopers… I’ll skip on the technical for now (most probably will do another post once the recordings are made available), and in this post I would like to put the focus on the human side.
We have the most amazing trainers this year lined up for Blackhoodie at Troopers 2019. We have Thais, Silvia, Lisa and Ninon going to give workshops on various interesting topics! Below are some of the workshop contents:
We’re regularly asked to review IPv6 address plans from different organizations and I’d like to share some reflections from such a process currently happening. I’ve discussed a few aspects of IPv6 address planning before; those readers interested please see this post which contains some references.
Some years ago Christopher wrote two posts (2016, 2015) about the IPv6-related characteristics of the WiFi network at Cisco Live Europe. To somewhat continue this tradition and for mere technical interest I had a look at some properties of this year’s setting.
