Beer-Talk in Berlin: Manipulating LLMs – How to confuse ChatGPT

AI is the new hot topic. Assistants like ChatGPT, Stable Diffusion, or Midjourney, which can perform various tasks for their users, become more and more parts of our lives. But what if hackers manipulate these assistants? Find out at our Beer-Talks in Berlin and St. Gallen!


This Beer-Talk (in German) is divided in technical presentation of about 40 minutes followed by a stand-up snack. The participation is free of charge.



Artificial Intelligence (AI) refers to the ability of computers and machines to imitate or simulate human-like thinking and behavior. AI systems can be applied in various fields, such as task automation, image and speech recognition, medical diagnostics, financial analysis, and much more.

Prompt Injections are a new type of attacks, in which hackers abuse an AI to gain sensitive information, manipulate information, and more.

The focus of this talk is to analyze such attacks and discuss prevention mechanisms.
