Information Security

After not having the the monthly meetup of march, we are back on **14 april** at **Enrise**! Pascal Baljet will join us to talk about Laravel and Inertia. js! Enrise is easily reachable by car (located right next to the A1 exit "Amersfoort Noord") as well as by public transport (there is a bus stop 100m walking from the office). If you are coming by car, you can park your car on the roof of the building. Also good to know; **Enrise will be sponsoring Pizza for this meetup** 🍕! 18:30 - Pizza delivery (around this time) & doors open 19:30 - **Modern front-end without API: Laravel + Inertia. js** \- Pascal Baljet 20:30 - Social **Modern front-end without API: Laravel + Inertia. js** Inertia.js lets you build modern single-page applications using your favorite backend and frontend frameworks, without needing to write an API. You use server-side routing and controllers, but render frontend components instead of server-rendered templates. In this talk, I’ll show how features like forms with real-time validation, deferred props, prefetching, infinite scroll, and polling work. All within a single repository.

**📣 Registratie voor deze editie gaat vier weken voor aanvang open! 📣** **17.00 - 18.00** Inloop & eten **18.00 - 18.10** Openingswoord InSpark **18.10 - 19.00** **Barry 'fish_' van Kampen** - *Own the PWNage: Waarom ik op 14 duizend linkjes per dag klik* Securityteams rennen van incident naar incident, terwijl aanvallers rustig onze infrastructuur verkennen. We zitten op een goudmijn aan data, maar kijken zelden naar wie er daadwerkelijk interesse toont in onze omgeving. In deze sessie laat ik zien hoe deception engineering je helpt om die nieuwsgierigheid meetbaar te maken en hoe je met je bestaande data aanvallers ziet voordat er impact is. In kijkje in de keuken: \- MITRE ATT&CK vanuit een offensief perspectief\. \- Welke goudpot zitten we al op? \- Wat kunnen we met deze data? \- Welke data willen we nog meer zien? \- Wat zijn onze reacties en waar kunnen we verbeteren? **19.00 - 19.10** Break **19.10 - 20.00** **Derk van der Woude** - *Security for AI Agents* Met de opkomst van AI-agents binnen het Microsoft-ecosysteem ontstaan er nieuwe uitdagingen op het gebied van identiteit en beveiliging. Hoe authenticeert een agent? Hoe beperk je wat een agent mag doen? En hoe detecteer je afwijkend gedrag voordat het een probleem wordt? **20.00 - 20.10** Break **20.10 - 20.30** Pubquiz! 🕺🏻🎁 **20.30 - 21.30** Borrel en einde

**Um was geht es dieses mal?** Dieses Mal findet das Meetup in Kooperation mit dem **n8n Meetup im Ruhrgebiet** statt und wird wie immer bei uns bei codecentric in Dortmund ausgerichtet. Beim 3. n8n Meetup im Ruhrgebiet geht es wie immer darum, die Möglichkeiten von n8n besser kennenzulernen, Erfahrungen zu teilen, voneinander zu lernen und sich mit anderen auszutauschen. Dieses Mal steht das Meetup zusätzlich im Zeichen von Vibe Coding und schnellem Prototyping. Im Fokus steht, wie sich n8n als Backend für Automatisierungen, Schnittstellen und Logik im Hintergrund mit Vibe Coding für die schnelle Entwicklung von Frontends verbinden lässt, um in kurzer Zeit funktionierende Prototypen, interne Tools und erste MVPs umzusetzen. Anhand konkreter Beispiele und Live-Demos zeigen wir, wie aus einer Idee schnell etwas Nutzbares entsteht. **Hybrides Setup!** Wir freuen uns, euch bei uns in den Räumen der codecentric AG in Dortmund willkommen zu heißen. Vor Ort versorgen wir euch mit Snacks und Getränken und freuen uns gleichzeitig über interessante Diskussionen und einen guten Austausch. Für alle, die es nicht zu uns ins Office schaffen, werden wir das Meetup Hybrid durchführen. Der Stream beginnt ca. 10 Minuten später, damit wir vor Ort ausreichend Möglichkeit für persönliches Kennenlernen haben. Den Live-Stream findet ihr auf dem [YouTube-Channel](https://www.youtube.com/@codecentricAG) der codecentric AG. **Wichtig - Absage bitte rechtzeitig:** Wir bestellen das Essen bereits 3 Tage vor dem Meetup. Falls ihr doch verhindert sein solltet, bitten wir euch um eine rechtzeitige Absage. Das ist wichtig, damit wir nicht unnötig Essen verschwenden müssen. Vielen Dank für euer Verständnis! **Anreise:** Per Zug: Vom Dortmunder HBF sind es ca. 10 Minuten zu Fuß. Mit dem Auto: Rund um das Office gibt es einige Parkflächen, dazu befinden sich in dem Parkhaus der Thier-Galerie weitere Parkplätze.

Experienced CISO in Retail Banking, Media Broadcasting and Enterprise Software industries. Balancing engineering background with a pragmatic, people-centric approach. Credentials include AIGP, CISSP, CISM, CCSP, CIPP/e, and Lead Implementer ISO/IEC 42001:2023 (AIMS). **Bot vs. Bash: How Modern Threat Actors are Actually Using AI** **Abstract:** Generative AI has rapidly shifted to become a defining element of the modern threat landscape. This has resulted in great interest from a cybersecurity perspective and numerous discussions about its potential impacts. However, moving beyond speculation, this session presents real-world observations from the front lines of threat intelligence to demonstrate exactly how adversaries are utilizing these tools today. We will explore how state-sponsored APTs and financially motivated actors integrate Large Language Models (LLMs) to sharpen the quality of social engineering, reconnaissance, and code generation. Rather than focusing on “super-malware” theories, we dive into specific “in the wild” use cases to provide defenders with the practical context needed to identify and counter AI-augmented threats within their own environments. **Bio:** Daniel Kapellmann Zafra is Technology Strategy Lead in Google Threat Intelligence, where he designs the future of large-scale investigative frameworks. With a specialized background in Information Operations (IO) and Cyber-Physical threats, Daniel has spent his career working with different threat intelligence teams to scale the breadth and depth of intelligence investigations. He currently spearheads initiatives at the intersection of AI and threat intelligence, focusing on how emerging AI ecosystems redefine both the threat landscape and the efficiency of modern cybersecurity. A former Fulbright Scholar and University of Washington Informatics alumnus, Daniel was previously recognized by the Kaspersky Academy Talent Lab for innovation in security architecture.
