🗣️ Our talks
Talk 1: Chatless-AI - Developing real-time language interfaces for web and mobile (Sascha Lehmann)
Real-time language models like GPT-Real-Time and Gemini Live are giving rise to a new generation of interfaces: speech is becoming an instantly responsive, low-latency channel of interaction—no prompting, no waiting, and hands-free. In this talk, Sascha Lehmann demonstrates how real-time models work technically, how to reliably control contextual boundaries, roles, and security, and how real-time AI can be specifically integrated into web and mobile applications—from architecture and cost optimization to UX that guides users transparently through the dialogue.
Talk 2: Broken Access Control: Why BOLA, BOPLA, and BFLA Remain the Biggest Risks in 2025 (Martina Kraus)
The OWASP Top 10 was newly released in 2025 – and once again, Broken Access Control takes first place. This talk examines three critical vulnerabilities: BOLA (Broken Object Level Authorization), BOPLA (Broken Object Property Level Authorization), and BFLA (Broken Function Level Authorization). Why are these among the most common security flaws? And how can we systematically protect against them? Using concrete code examples, this presentation demonstrates how effective authorization works and how the attack surface can be reduced with the right design patterns.
