Are you a cybersecurity professional navigating the challenges of building or joining high-performing teams? Whether you're scaling a SOC, hiring your next pentester, or preparing for your next move, this edition of the Berlin Cybersecurity Social is for you.

Join us for an evening of real talk on one of the most mission-critical — yet overlooked — elements of security work: hiring.

Agenda:

• 7:00 PM - 7:15 PM: Welcome

• 7:15 PM – 7:45 PM: Lightning Talk – “The Hiring Gap: Why Great People Get Overlooked (and What to Do About It)” * The stakes are high in cybersecurity — and the cost of a bad hire, or a missed opportunity, can ripple across the entire organization. * In this talk, Konstanty Sliwowski, Founder and Lead Trainer of The Hiring School, breaks down what he calls the hiring gap — the disconnect between how hiring actually works in tech vs. how it could work with just a bit more clarity and intention. * Drawing on 20+ years of technical hiring experience, Konstanty will explore: - Why so many strong candidates don’t make it past the interview process - The hidden biases and missteps in tech hiring — especially in cybersecurity roles - How both hiring managers and candidates can take a more intentional\, effective approach

• For managers, it’s about getting sharper on how you define success, how you structure interviews, and how you make decisions that actually strengthen your team. * For candidates, it’s about learning how to position yourself, spot real opportunities, and lead conversations that uncover what you need to make the right choice. * Whether you’re hiring, interviewing — or doing both — this session will give you practical ways to shift the hiring game in your favour.

• Who Should Attend: * - Cybersecurity professionals of all kinds - Hiring managers and team leads - Candidates navigating the job market - Anyone curious about building better teams and careers *

Real-Time Audio in Rust: A Practical Guide for C++ Developers Stephan Eckes

While many of the biggest software companies are moving from C++ to Rust, most of what you hear online is about how much "safer" and faster Rust is—often from the perspective of web developers. But does it actually help when you're writing real-time code? And what does it change in your day-to-day work?

After three years of building real-time audio systems in Rust, I’ll share what really mattered to me after switching from C++. This talk is about the practical side: what got better, what stayed tricky, and how Rust actually helped me write safer and more reliable real-time audio code.

Stephan is a software engineer at ai\|coustics\, where he is responsible for the SDK that runs neural networks for real-time audio using a custom inference engine written in Rust. He previously studied at the Audio Communication Group at TU Berlin and has worked as a DSP and plug-in developer for u-he\, Holoplot\, and Neumann. In his spare time\, he maintains open-source libraries and creates coding tutorials on YouTube.

Talk #1 How to Hack an Agent – or Not Thomas Fraunholz Senior Researcher AI @ Smart Labs AI Large language models (LLMs) are not as secure as they seem. Beyond their tendency to “hallucinate,” they can be manipulated using jailbreaks and adversarial prompts, bypassing safeguards designed to keep them in check. But the real challenge arises when LLMs are connected to agents with real-world capabilities—like sending emails. This talk explores the security risks of AI agents and the ongoing research into making them more resilient. Using the "Adaptive Prompt Injection: LLMail Inject" challenge from the IEEE Conference on Secure and Trustworthy Machine Learning as a case study, we’ll examine how Microsoft’s Phi3 and OpenAI’s GPT-4o-mini handle adversarial attacks. We’ll break down security techniques like LLM judges, task drift detection, and prompt shields—critical concepts as the EU AI Act's security mandates take effect in August 2025. Attendees will gain insights into the strengths and weaknesses of current AI security mechanisms and learn practical strategies for assessing the safety of AI agents in production environments.

About the Speaker Thomas is an MLOps and NLP expert with a background in applied mathematics and embedded programming. He has led two publicly funded AI research programs with the German Aerospace Center and is currently focused on AI-driven cybersecurity at Smart Labs AI GmbH. In his spare time, he’s developing a low-budget drone system for detecting bark beetle infestations, blending his passion for AI and embedded systems.

Welcome to the inaugural event of the Audio Developer Meetup Berlin!

Join us to celebrate the start of this event series. For this very special occasion, we will be looking forward to talks by two world-renowned speakers: interdisciplinary artist and designer Astrid Bin and C++ guru Timur Doumler.

After the talks there will be time to network over drinks and pizza. Anyone interested in Audio development is welcome!

How to get to the venue: Unfortunately, the pin that meetup is showing for the event is not quite accurate. Holoplot is located here. You will need to enter the courtyard at Ringbahnstr. 10-14 and then walk to the entrance A2. The meetup will be on floor 4. Please use the stairs if possible. If you need to take the lift then please ask someone from Holoplot for assistance.

Talks: You've made it, now explain it Astrid Bin

Making the thing is one part of the design process, but documentation is part of a broader process of designing any hardware or software product, and one that has a significant impact on how and why people buy what you make. Music technology is particularly tricky, because no matter how intuitive the design people need to be able to start somewhere and learn how to use it, and use it in their own creative context. In this talk Astrid shares lessons she's learned through incorporating documentation into the design process of Bela, a hardware system for creating interaction with sensors and sound, as well as Bela's other products that range from touch sensors to synth modules.

Demystifying std::memory_order Timur Doumler

Atomic variables are an essential tool for programming for real-time audio processing as they are needed to implement any kind of lock-free algorithm or data structure. In C++, atomic variables are readily available in the Standard Library through std::atomic. In order to use std::atomic in an efficient and performant manner, it is crucial to pick the correct memory order for the atomic operation at hand depending on the requirements of the algorithm, which can be accomplished via the std::memory_order parameter that every atomic operation in C++ accepts. Yet memory order in C++ is notoriously hard to reason about and often misunderstood. In this talk, we give a brief overview over the C++ memory model, explain the differences between relaxed, consume, acquire, release, and sequentially consistent memory order, and give some guidelines for which to use when working with atomic reads, writes, read-modify-write operations, and memory fences.
