The TAICO team is happy to announce our next meetup at the Adaptavist office in Toronto. Much thanks to [Adaptavist](https://www.adaptavist.com/) for hosting! **Wayfinding** * *Please be careful when using maps features on phones, some people have been redirected to a completely wrong address. The event is near Winners on Front St, which is just south, across the street, from Berczy Park (where the dog fountain is) so if you are not near that area, you are in the wrong place.* **Registration and Event Details** Our goal is to bring artificial intelligence and cybersecurity together. To do that, we need to explore what's happening in AI and what's happening in cybersecurity, and where the two intersect and collide. We're also working to understand how we solve problems in these areas, what that looks like, and how Canada can and will participate. With that in mind, we're pleased to announce our speaker and the agenda for our next meeting! **Sponsors** And thanks to our host, [Adaptavist](https://www.adaptavist.com/)! **Notes** * *Unfortunately, we won't have pizza at this meetup due to a gap in sponsorship. We're actively working on securing sponsors for future events.* **Agenda** **Doors Open: 5:30PM** **Event Start: 6:00PM** * 👋 **Welcome and introductions** * 🙏 **Thank you to our amazing hosts and sponsors!** 🎉 * 🎙️ **Speakers** 🎤 **Speaker #1: Curtis Collicutt** *Title: Stegalographer* *Abstract:* ***They said never write your own encryption. They didn’t say anything about steganography!*** *What if the best place to hide a secret message was in something so boring that nobody would ever look twice at it? Stegalographer is a tool that embeds data in legitimate-looking application logs by encoding information in the choices that generate the logs, rather than encrypting them. The template used, the number of trailing spaces, whether the log says 'error' or 'failure', and even the microsecond variations in timestamps can all carry hidden bits. The output isn't logs with secrets stuffed inside, but real log structure with your data silently riding along.* *This talk will explain how Stegalographer works, from analysing existing logs to extract templates (using the Drain algorithm from log analytics research), to the encoding process that turns your message into a stream of plausible entries. We will explore practical use cases such as covert channels in penetration testing, watermarking logs to trace leaks and censorship-resistant publishing disguised as 'sample data'. However, we will also be honest about the limitations: this is steganography, not encryption, and statistical analysis can potentially detect anomalies at scale. Whether you're interested in security research or information theory or privacy, or want to know more about building security tools, come and see how the most mundane part of any system can become a covert communication channel.* *We'll also touch on the experience of building security tools like this one using AI-assisted programming tools like Claude Code.* 🎤 **Speaker #2: Ads Dawson** Title: *Q&A with Ads Dawson* *Ads Dawson is an Offensive security engineer, penetration tester and red teamer with over thirteen years of experience breaking, testing, and securing applications and infrastructure across startups and large enterprises. Skilled in web application security, DevSecOps, and large-scale hybrid cloud environments, with a strong focus on offensive engineering, red team operations, and vulnerability research. Active bug bounty hunter and researcher in AI and LLM security, specializing in uncovering and mitigating attack vectors such as prompt injection, unrestricted model inference, and backdoor attacks. Experienced in leading incident response and simulating advanced adversaries to expose weaknesses before real attackers do.* *He works with organizations like OWASP and was Technical Lead for [OWASP’s Top 10 for LLM Applications](https://owasp.org/www-project-top-10-for-large-language-model-applications/assets/PDF/OWASP-Top-10-for-LLMs-v2025.pdf).* *This is your chance to ask Ads anything you want about AI and cybersecurity so come armed with your questions!* **⚡ Lightning Talks and Demos** Lightning Talks - 5 to 10 minutes long 1. Elshad Humbatli - Repo Health software project 2. **You?** \- Please reach out if you'd like to do a lightning talk or demo Please reach out to us if you'd like to present at the meetup.

Power grids run on protocols that were never designed to be secure. Modbus doesn't authenticate. MQTT trusts whoever connects. State estimation believes whatever data you feed it. This month, Parham Mohammadi shows what happens when you exploit all of that. **THE TALK** Parham built a full ICS attack simulation lab and ran real attack chains against it. False data injection into state estimation. Modbus register overwrites. MQTT broker takeover. Chained attacks against distributed energy resources. The operator dashboard stayed green the entire time. If Ukraine 2015 and Industroyer taught us anything, it's that this isn't theoretical. **THE SPEAKER** Parham Mohammadi — Postdoctoral Researcher, York University Parham spent six years at York doing his PhD on power systems simulation. The CPPS-SEC Lab he built for this research simulates real ICS attack chains against power grid infrastructure — the same lab he's demoing at this talk. ***ARRIVAL WINDOW — PLEASE READ*** Doors open at 6:15 PM and close at 6:40 PM. Our volunteer at the gate can only let people up during this window. After 6:40 PM, there will be no one downstairs to let you in. Plan accordingly. If you RSVP and can't make it, please update your status so someone on the waitlist can take your spot.

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/Da9fZFxPfs **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do. * Please buy a drink, and tip the barista well.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
