Hello, I’m Mateusz
Jarząbek

I work as a Senior Offensive Security professional in EY’s internal Purple Team – combining both offensive and defensive security practices to defend the firm.

Here I’m sharing knowledge to help you master Active Directory Offensive Security. I know it is an extremely large and complex topic. Learning resources are spread across countless sites, forums, and courses.
Many times I struggled to connect the dots, constantly pivoting between incomplete sources of information, and couldn’t say where I am and what should I do.

Losing my way at times, I decided to create this blog where you will have all the necessary resources to learn and navigate the topic with exact awareness where you are and what you can do.
My goal is to not only explain the specialized concepts you need but also to give you a unique and structured approach that helps you visualize the entire idea while leveling up your skills.

Curious about what’s next? Let’s dive in together – follow me on linkedIn and subscribe to my newsletter, skip the frustration, get better, and save time along the way.
