Gender equality in the Infosec world as a topic of discussion comes with a lot of heated arguments and differences in opinion.
So let me start with some disclaimers on the target audience for this post. If you are in the category who believes everything about gender is perfect in the infosec world, this post is not for you. If you are in the category who believes gender and bringing diversity is not your area of interest, then this post is not for you either. There are so many interesting problems that the world offers you. Climate change, poverty, diseases, unemployment, addiction, science problems and what not. Everybody has the freedom to choose their area of interest and contribute towards it. If you are in the category who thinks gender equality in infosec needs some attention and would like to explore more on the topic without prejudices, then this post may be interesting to you.

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…
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.

In Mai 2018, Tobias and me were in Cologne at the Building IoT conference. The topics of the talks covered a broad spectrum of the Internet of Things field. There were three tracks covering different topics ranging from the jungle of IoT protocols, secure Linux hypervisors specially developed for IoT modules to machine learning and blockchain.
IoT is everywhere right now and there are a lot of products out there. I have been looking at an IP Gateway lately and found some serious issues. The Busch-Welcome IP-Gateway from Busch-Jaeger is one of the devices that bridges the gap between sensors and actors in your smart home and the network/Internet. It enables the communication to a door control system that implements various smart home functions. The device itself is offering an HTTP service to configure it, which is protected by a username and password. Some folks even actually expose the device and its login to the Internet. I tried to configure one of these lately and stumbled upon some security issues that I would like to discuss in this blog post. Continue reading “Security of Busch-Jaeger IP Gateway”
We are very excited to publish some (more to come!) of our photos from TROOPERS18! Based on feedback from #TR18 we would also like to take a moment for our official TROOPERS photographer to introduce himself and tell you a little about what inspires him.
Last week (25th – 27th April), I attended the “Sicherheit 2018” in Konstanz which is the annual meeting of the security community of the Gesellschaft für Informatik e.V. (GI) in Germany. The conference is in equal proportions attended by researchers and people of the industry working in security-related disciplines which lead to lively and pleasant discussions conversations.

Lately I’ve been analyzing a .NET binary that was quite interesting. It was a portable binary that shipped without any third-party dependencies. I started looking at the .NET assembly with ILSpy and noticed that there was not that much code that ILSpy found and there were a lot of references to classes/methods that were neither in the classes identified by ILSpy nor were they part of the .NET framework.
