Speakers
Trustworthy AI: How to Prevent Your Machine Learning Models From Becoming a Security Liability
As AI systems power more products, decisions, and customer experiences, one uncomfortable truth is emerging: machine learning introduces entirely new privacy and security risks that most organizations are not prepared for. Models can leak sensitive data, be reverse-engineered, manipulated, or compromised. This talk demystified what can go wrong when deploying AI in real-world environments and showed how to build trustworthy, resilient, and regulation-ready ML systems.
Speaker: Anastasia Pustozerova
Anastasia received her bachelor’s degree in Applied Mathematics & Physics from St. Petersburg University. She has a joint master’s degree from a European Master’s Program in Computational Logic (TU Wien, TU Dresden, Free University of Bozen-Bolzano). Anastasia is currently working towards a PhD. She is involved in an European research project FeatureCloud as an expert in federated machine learning, where she is working on cyber risk assessment and mitigation.
Speaker: Tanja Šarčević
Tanja received a bachelor´s degree in Computer Science from the University of Zagreb and a master´s degree in Logic and Computation at the TU Wien. She is currently working towards her PhD degree with the focus on ownership protection of data and machine learning models.
Using LLMs for Offensive Security
Since 2023, researchers have used LLMs to drive offensive security, e.g., pen-testing. This talk highlighted academic research on LLM-driven pen-testing between 2023-2025, showed (the speaker’s) current prototypes/research, and detailed current engineering/research questions.
Speaker Andreas Happe:
Andreas is a developer gone pen-tester gone phd student that currently focuses on the the intersection between LLMs and Penetration-Testing. Otherwise, you can spot him failing at local bouldering gymns.
About the Meetup
As the OWASP Vienna Chapter, our mission is to connect people, share knowledge, and advance software and IT security within our community. We aim to create an open and collaborative environment where security professionals, researchers, students, and enthusiasts can learn from each other, exchange ideas, and build meaningful connections.
Whether you’re deeply specialized in application security or just beginning to explore the field, our events and activities are designed to provide valuable insights, hands-on learning opportunities, and a strong network of like-minded individuals.
