Keynote Speaker

< Talk Abstract />

LLMs are omnipresent and being bolted onto almost every piece of Software nowadays. While convincing a web shop’s AI chat bot to give you bomb building instructions might be a fun exercise, the real problems start to arise when we let those bots do things on our behalf.

Brace yourself for some horror stories about prompts, injections and AI (double) agents meeting classic application security issues. But also let us have a look at safeguards, mitigations and potential ways to not let a vibe coding session ruin your production database completely.
