The Attacking Active Directory Game - Can you outsmart the Machine Learning model? Help us by playing the evasion game!

The Attacking Active Directory Game - Can you outsmart the Machine Learning model? Help us by playing the evasion game!

The “Attacking Active Directory Game” is part of a project where our researcher Ondrej Lukas developed a way to create fake Active Directory (AD) users as honey-tokens to detect attacks. His machine learning model was trained in real AD structures and can create a complete new fake user that is strategically placed in the structure of a company.

Creating "Too much noise" in DEFCON AI village CTF challenge

During DEFCON 26 the AI village hosted a jeopardy style CTF with challenges related to AI/ML and security. I thought it would be fun to create a challenge for that and I had an idea that revolved around Denoising Autoencoders (DA). The challenge was named “Too much noise” but unfortunately it was not solved by anyone during the CTF. In this blog I would like to present the idea behind it and how one could go about and solve it.
