Continue readingA few notes on WordPress Security
Taking a look at the CVE List for WordPress, most vulnerabilities aren’t found within the WordPress core but inside of third-party plugins and themes.
Today, let’s talk about WordPress.
Performing a WordPress assessment might seem boring at first as core functionality [tested] and configuration does not allow for extensive security misconfigurations. Luckily, most instances use plugins and themes to add features not offered by the WordPress core.
In this blog post I would like to discuss the findings and how I discovered them. Also, I will describe different vendor responsiveness reaching from not responding at all, to not understanding the issue to fast and professional responses kindly asking for a review of the updated code ready for deployment.

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.

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…”
Continue readingPoSh_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.
