Software Security

**About** Would your embedded product benefit from application logic updates that do not require changes to the full firmware? Or a mechanism for your customers to tweak and extend the functionality of the product? Using their favourite language(s), without proprietary tooling? And all that while your product stays secure, no matter how creative said customers get? WebAssembly (abbreviated Wasm) might be exactly what you are looking for. Join us this evening to learn about the state of the art of running WebAssembly on MCUs, and to experience a practical example of a real world, production grade embedded code base targeting WebAssembly and running in a browser. Merging the two approaches is then left to the visitors as a take-home exercise. **Presentations** 1. 15’: Welcome (Urs/Reto and SCS) 2. 40’: Browser technology on the MCU? Introduction to WebAssembly, overview of existing embedded runtimes, use cases, discussion. (Pascal Mainini) 3. 30’: Unlocking Bluetooth Connectivity in Browsers: From Sensors to Audio (Matthias Ringwald) Presentations start at 19:00. Afterwards we’ll have plenty of time to discuss and socialize. **About the speakers** * [Pascal Mainini](https://mainini.ch/) is a teacher and researcher at [Berner Fachhochschule](https://www.bfh.ch/en/about-bfh/people/kkmsprgzbqc2/), focussing on the security of embedded systems and the Internet of Things. * [Matthias Ringwald](https://www.linkedin.com/in/matthiasringwald/) is a Co-Founder of [BlueKitchen GmbH](https://bluekitchen-gmbh.com/) and develops their Bluetooth stack.

Hi! I’m Stephanie, a product designer based in Zurich. I’m looking to build a community of curious designers, developers, product managers, and other creative technologists who enjoy thoughtful conversations outside the usual networking events, conferences, and office spaces. This summer, we’ll meet at local Badis and neighborhood pools around Zurich to relax, connect, and share ideas in a casual setting. Bring a passion project, a problem you’re thinking about, an interesting article, a new tool, or simply your perspective. Topics might include: * Design, technology, and product thinking * Ethical, responsible, and sustainable uses of AI * Creativity, learning, and personal projects * Philosophy, culture, and the future of digital products The goal isn’t pitching, recruiting, or performing expertise. It’s creating a welcoming space to exchange ideas, practice communicating them, and learn from one another without judgment. If spending less time in meeting rooms and more time having meaningful conversations by the water sounds appealing, I’d love to meet you. See you poolside.

*Due to the weather forecast, we have decided to postpone the event until next Wednesday.* Let’s do something different from the usual meetup format. We’ll start with a scenic \~1.5h hike from Uetliberg to Felsenegg, with rotating discussion pairs and small groups along the trail. Every 20 minutes, we switch conversation partners and dive into a new topic around product thinking, leadership, team dynamics, facilitation, delivery, career growth, or whatever challenges are currently on your mind. The goal is simple: \*meet interesting people * exchange practical experience \*enjoy Zürich nature instead of another conference room. We’ll finish with a relaxed group dinner at Restaurant Felsenegg overlooking the lake and city. Start: 17:45 at Uetliberg station Route: Uetliberg → Felsenegg Hiking level: Easy/moderate Hiking time: \~1.5h Dinner afterward at Felsenegg Easy return via cable car + train Bring comfortable shoes, curiosity, and a topic you’d love to discuss. Four-legged networking companions welcome too.

Please see below for this event's description. **Visit our [Eventbrite page](https://www.eventbrite.ca/e/owasp-toronto-june-2026-tickets-1991326120030?aff=oddtdtcreator) to RSVP!** **Hybrid event:** * In-person: Security Compass, 325 Front Street West, Unit 103, Toronto, ON M5V 2Y1 * Livestream: https://www.youtube.com/watch?v=H5aZ_CwYEus Doors open at 6:00 PM. Presentation/livestream starts at 6:30 PM **Description:** AI split AppSec into two attack surfaces: your code, and the code factory that produces it—coding agents, the models and MCP tools they call, the developer environment itself. With exploits now landing in under ten hours and vulnerabilities shipping from more authors than ever, this talk lays out a staged path to a "Mythos-ready" program—reprioritizing around reachable risk, accelerating remediation, and securing the AI-SDLC—and argues security should stop filing tickets and start shipping fixes.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
