VidraSec was founded in 2024 by me, Martin Grottenthaler.
I have worked full-time in IT security consulting since 2017. My focus is on Windows, Active Directory and EntraID security, as well as the security of internal systems.

Talks at conferences
Here are some talks that I have presented at conferences.
Troopers 2023: The Power of Ceorcion Techniques in Windows Environments
IT-SECX 2021: Utilman is back (German)
Hacktivity 2023: The Power of Ceorcion Techniques in Windows Environments
Another (later) version of the talk I did at Troopers. It is a little bit shorter, but being the third time I’ve done the talk, it might be better. I will let you decide.
The name VidraSec
You might now be wondering about the name. Why VidraSec? First of all, let me tell you that finding a suitable name is one of the most complicated steps in founding a company.
“Sec” obviously stands for security. So, what does “Vidra” mean? Vidra is the slavic word for otter. 🦦 I chose the Slavic word mostly because it sounds nice and was not yet taken.
So, what do otters and security have in common? In the Catholic Church (at least in Austria), you cannot eat meat during the fasting period, but you can eat fish. People were quite smart and redefined all animals that live in the water as fish, to be able to eat them during the fasting period. So, otters were part of one of the first (life) hacks in the world.. Sadly, this was not very good for them (and their beaver 🦫 friends) because people nearly hunted them to extinction. But do not worry, nowadays they are protected!
