Back from PowerShell Conference Europe…

The PowerShell Conference Europe 2019 took place last week in Hannover, and I had the pleasure to attend and speak for the second year in a row. I want to thank @TobiasPSP @Alexandair @sqldbawithbeard and the @PSConfEU crew for putting up this #PowerShell feast. From a RaspberryPi to the Clouds, from PowerShell internals to a dancing Lego robot, if you have anything to do with windows, PowerShell, or a computer, there was some content made for you… Continue reading “Back from PowerShell Conference Europe…”

The “mmm…” in Community

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.

2019 – Year Of The Blue Dog…

Back from Holidays, you started the year well motivated to make the world a safer place.
However, sitting at your desk today  you realize nothing really changed since last year, and you are surfing the web, feeling a bit blue, trying to avoid that pile of emails waiting for you and wondering how you could gain some visibility on your domain in order to better defend it.
No worries, emails can wait a bit longer. All you need is some fresh air and something cool to keep your defensive mind motivated for the year,  and I might have just what you need; so put on your shoes and let me take you on a 15 minute Cypher walk with a cool blue dog…

The Dog Whisperer’s Handbook

Generally speaking, I’m more of a Cat type of guy, but I have to say I really love BloodHound. And if you do too, you are in for a treat…
Last week, the ERNW Insight Active Directory Security Summit took place in Heidelberg. (More Info)
For this occasion, @Enno_Insinuator asked me if I would like to deliver a BloodHound Workshop, and of course I accepted the challenge…

A little KeePass Mea Culpa…

Some weeks ago, I tweeted about grabbing clipboard content from KeePass with some PowerShell. From some reactions to this tweet, and after reading it a couple of times again, I realize it was sending the wrong message, and I would like to take a bit more than 280 chars to clarify what I meant when I posted that tweet…

TLDR: Password managers are a must, not using one exposes you to far more risks than using one. Do it.  Continue reading “A little KeePass Mea Culpa…”

PoSh_ATTCK – ATT&CK Knowledge at your PowerShell Fingertips…

When I recently joined the Windows Security team at ERNW, Enno asked me if I wanted to write a ‘welcome’ blogpost on a topic of my choosing… Up for the challenge, and since I had been playing with BloodHound & Cypher for the last couple of months, I first thought I would do something on that topic.

However, after gathering my thoughts and some Cypher I had collected here and there, I realized that the topic of Bloodhound Cypher might actually require several blog posts… And so I changed my mind. I will keep the joys of Cypher for later, and in this post, I will talk about a tiny tool I wrote to query the Mitre ATT&CK™ knowledge base from the comfort of a PowerShell prompt.
