The Association for Science and Reason will be holding our regular in-person Skeptics in the Pub event. (Monthly Zoom meetings will continue as usual, but we will also be doing monthly in-person events on the second Tuesday of every month). Our previous venue, Prenup Pub, has closed, so we will meet again this month at the Town Crier Pub, 115 John St, a 9 minute (600m) walk from St Andrew Station. It has very good food and a large seletion of beer. It was quite noisy the last two times we were there, but we'll give it another try to see what it is like this time. I have not yet found a better location. We will get together for a social event to say hello to people we may have only met on-line and to reconnect with some long-time acquaintances. We will not be having a presentation or a speaker, just a chance to sit down and have a meal and/or a beverage and a conversation with a pleasant group of fellow skeptics. Food and beverages are available from the menu. Foods include a full menu from soups and appetizers to entrées and dessert. The beverage menu includes over 50 different beers on tap, many bottled beers, a selection of wines, various cocktails, and as well as non-alcoholic drinks. When you arrive, just ask where the "Skeptics" are. If you plan on joining us, please register so we can estimate the number of attendees.

Please see below for details of our April 15 event. Visit our [Eventbrite](https://www.eventbrite.ca/e/owasp-toronto-april-2026-tickets-1986283430209) page to RSVP! APIs power virtually every web and mobile application, accounting for over 80% of all Internet traffic. And APIs are under attack. Gartner states APIs have become the “most frequent attack vector," resulting in hundreds of highly successful, high profile breaches. This API security presentation covers 1) why attackers love APIs, 2) real-world breaches (and how they map to the OWASP API Security Top 10), and 3) best practices to keep APIs secure.

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: How to Get to the Event** * *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 speakers 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: Dmitrii Strizhkov** ***Subject: Penetration Testing Automation with MCP*** ***Abstract:*** *This presentation talks about my journey as the penetration testing practice lead, covering how I was able to increase efficiency and speed up the execution of my team's projects. I will discuss what MCP is, introduce how it can help in reconnaissance and enumeration phases, and analyze the results. I will also demo a solution that everyone can implement using the n8n low-code platform. Additionally, I will discuss and show why agents can help us, pentesters, in writing the reports (do the boring and tedious stuff). In the end, I will delve into why several precautionary measures should be undertaken before sending sensitive client data to commercial LLMs and suggest several solutions based on my experience. And as the final point, I would want to encourage my colleagues to experiment with and implement their own MCP-based solutions to speed up and make their engagements more effective.* *About Dmitrii:* *Dmitrii is the head of offensive security/penetration testing and practice lead at Parabellyx Cybersecurity.* 🎤 **Speaker #2: David Ahmann** ***Title: Stop Is Not a Safety Control: What AI Agent Security Looks Like at the Runtime Boundary*** **Abstract:** *A lot of AI security discussion still focuses on prompts, policies, and tool declarations. Our research at ([CAISI](https://caisi.dev/)) has been looking at the harder question: what actually changes at execution time when an agent is told to stop, requires approval, or reaches a risky tool boundary? I’d share a practical, evidence-based talk on where AI agent control really holds or fails, drawing from our OpenClaw case-study work and our public research on agent governance, evidence posture, and approval gaps. The goal would be a practitioner-focused session for security leaders, builders, and evaluators trying to separate demo confidence from real control.* **⚡ Lightning Talks and Demos** Lightning Talks - 5 to 15 minutes long 1. Curtis Collicutt - A demo of a new programming language: [Vary](https://varylang.com) \- A typed language design to find "lies" in generated code 2. Janhavi Doshi - "Data, LLMs and the Law - What Every Builder in Canada Needs to Know Right Now" 3. **You? - Please reach out if you'd like to do a lightning talk or demo - anyone is welcome to demo something they are working one** Please reach out to us if you'd like to present at the meetup. We are looking for people to talk about what they are working on, what they are building and learning, and are open to any level of experience and technical depth. Whether you are a beginner or an expert, we want to hear from you! We're all just out here building and learning. 👋 **See You There!** Thanks, and we look forward to seeing you at the meetup!

Most people hear "Evil Twin" and think fake login page at a coffee shop. Harvest some passwords, call it a day. That's the tutorial version. That's not what this talk is about. Harold "superkojiman" Rodriguez is going to show what happens when you actually build out Evil Twin infrastructure and use it as a real attack platform. Not just phishing — direct methods of gaining access to target systems. The tooling, the infrastructure, the tradecraft. How a technique most people write off as basic becomes a legitimate entry point in an engagement. **What we'll cover:** \- How Evil Twin setups go way beyond credential harvesting \- Direct methods for gaining access to target systems \- Attack chains that start with network positioning \- Real\-world scenarios where these techniques actually matter \- The defensive gaps most security teams miss **About the speaker:** Harold has been doing this for over 15 years. Red team operations, penetration testing, vulnerability research, exploit development — the full spectrum. He's authored boot2root and CTF challenges, built open-source security tools, and written tutorials that have been floating around the community for years. If you've done any offensive security training or CTF work, there's a good chance you've run into his stuff. **Details:** \- Thursday\, April 16\, 2026 \- Doors at 6:30 PM\. Talk starts shortly after\. \- Stan\, 100 Queens Quay East\, Toronto Stick around after for the hallway track. That's where half the good conversations happen. DC416 is Toronto's DEFCON group. Monthly meetups. Technical talks. No vendor pitches. No fluff.

This is a ticketed event. Please register at [this link](https://luma.com/lpikw708). ​Ryan Faulkner explores various papers that address cooperation and safety in multi-agent LLM simulations. Some of the core topics will include: * ​Moral behaviour of agents in high-stakes, zero-sum, and morally charged social dilemmas * ​Governance and sanctioning dynamics and the ways that LLM agents often fail to cooperate and free-ride in common-pool resource game * ​Mechanism design interventions like mediation, contracts, and elected leadership are explored to steer agents toward safer outcomes. ​This research also reveals that LLMs adapt their behavior based on awareness of their conversational partner's identity. ​​​**Event Schedule** 6:00 to 6:30 - Food and introductions 6:30 to 7:30 - Presentation and Q&A 7:30 to 9:00 - Open Discussions ​​​​​​If you can't make it in person, feel free to join the live stream starting at 6:30 pm, via [this link](https://www.youtube.com/@Trajectory-Labs/live).

**This is a ticketed event. Please register at [this link](https://luma.com/zcsyrtrx).** ​With [Duncan Cass-Beggs](https://www.cigionline.org/people/duncan-cass-beggs/?utm_source=luma), Executive Director of the Global AI Risks Initiative at the Centre for International Governance Innovation (CIGI). ​Prominent AI scientists and national security experts are raising the alarm that it may soon become technically possible to build autonomous AI systems capable of posing an extinction risk to humanity. While timelines are uncertain – with most informed estimates ranging from 2 to 10 years – recent advances suggest that AI systems could soon reach a critical threshold and feedback loop of recursive self-improvement. In this context, societies and governments must prepare now to address the most challenging AI scenarios. ​Based on current trends, the most powerful AI systems will likely be developed by frontier AI companies in the United States or China. Canada, like most other countries, therefore, lacks direct influence over the AI developments that may most affect our future. This doesn’t mean we have to resign ourselves to a fate determined by others. Along with efforts to promote AI adoption, innovation, and sovereignty, Canada can help to lead an international effort to avoid the worst global scale risks of AI – and make sure AI goes well and for the benefit of all. The challenges – technological, philosophical, political – are complex and daunting, especially under possibly very short timelines. But they are challenges most worthy of our commitment in this tumultuous and pivotal time. ​Building on CIGI’s recently published [Special Report on AI National Security Scenarios](https://www.cigionline.org/publications/ai-national-security-scenarios/), this session will lay out the key arguments for an international coalition of willing middle powers and others to lead urgent efforts to address global scale risks from AI. The session will then engage participants in a roll-up the sleeves discussion of Canada’s potential interests, roles, and points of leverage, and how best to rapidly mobilize Canada’s contribution. ​​​**Event Schedule** 6:00 to 6:30 - Food and introductions 6:30 to 7:30 - Presentation and Q&A 7:30 to 9:00 - Open Discussions ​​​​​​If you can't make it in person, feel free to join the live stream starting at 6:30 pm, via [this link](https://www.youtube.com/@Trajectory-Labs/live).

Join Liberty Labs Toronto for our tenth meetup on **Thursday, April 16, 2026, at 7:00 PM** near Yonge and Eglinton! We’ll examine one of the most contentious issues in libertarian thought: patents, copyrights, and intellectual property laws. Are they legitimate protections for creators, or state-enforced monopolies that stifle innovation, raise prices, and violate the principles of true property rights? This will be a balanced, thought-provoking discussion covering: * The philosophical case for and against IP * How patents actually work in practice (pharma, software, everyday inventions) * Real-world effects on innovation, competition, and consumer costs * Alternatives like trade secrets, first-mover advantage, and open-source models * Canadian-specific IP rules and how they impact independent creators and entrepreneurs What to expect: * Open, respectful discussion with plenty of room for different libertarian viewpoints * Complimentary appetizers and a drink ticket * Everyone who attends will receive a million-dollar Zimbabwe note as a fun take-home reminder of real value vs. fiat illusions * Connect with 10-20 liberty-minded Torontonians Venue: Pickle Barrel (2300 Yonge St, at Yonge & Eglinton), right above Eglinton Station. Easy parking in the Yonge Eglinton Centre garage or nearby Green P lots.

The next NoVABeerSec event - "Informal Gathering of Security Minds Over Beer" will be Wednesday, April 29th, 5:30PM til 7:30ish at Aslin Beer Company - Herndon Taproom (767 Elden St., Herndon VA 20170). **Venue for April:** Aslin Beer Company (https://www.aslinbeer.com) - Aslin Beer Co. was founded in 2015 by Andrew Kelley and Kai Leszkowicz. The name, Aslin, comes from the family that connected Andrew and Kai through marriage; they each married a daughter from the Aslin Family. Andrew’s professional background was in finance and consulting, while Kai worked in public service. They bonded over a shared interest of craft beer and home-brewing, which eventually lead to the idea that “We can do this too.” **Additional Info:** We are an inclusive group, so if we missed anyone please let us know or if you want to bring your significant other/spouse please do. We do know there are folks that have changed roles since we last met so please also let us know if we need to add new contact info for people. Have a great week and see you later this month! Cheers, Rinaldi Rampen & Mike McCabe of @NoVABeerSec

**Agenda :** * 4.45 to 5.00 PM ET: Food and Networking * 5.00 to 5.50 PM ET: "Hands-On : GitHub Copilot SpecKit" Hello Everyone! Please join us for our April 14th edition of the AI-ML MeetUp. **Please note this is an in-person meeting and light refreshments/food will be provided. You will need a government-issued ID to enter the facility.** **Title:** Hands-On : GitHub Copilot SpecKit **Description:** Spec-Driven Development **flips the script** on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: **specifications become executable**, directly generating working implementations rather than just guiding them. In this hands-on lab, we will be covering building your application using SpecKit. Pre-requisites: VSCode v1.107, GitHub Copilot, Python 3.13 + uv, Git installed. **Location:** The meeting will be hosted in the Applied Information Sciences ( AIS ) office in Reston, at 11440 Commerce Park Dr # 600 · Reston, VA. The location is also right off the Silver Line metro's Wiehle-Reston Metro Station. **Parking:** Parking is paid and can be validated at the AIS office reception. We will meet in Room Lake Anne. We hope to see you all there!!!!

Most AI meetups end up as just networking. **We’re different.** At **AI Tool Explorers Night \| Connect & Make New Friends**, you’ll: ✨ Walk away with a *real learning nugget* (a tool, workflow, or strategy you can use immediately) ✨ Connect with people who share your curiosity for AI, productivity, and automation ✨ Enjoy a fun, casual setting where new ideas and friendships spark naturally 👉 **Our promise:** every session delivers structure, substance, and takeaways you can use when you get home. ### 📅 Event Flow * **6:00–6:15 PM** → Arrivals & intros * **6:15–6:45 PM** → AI demo / learning nugget * **6:45–7:00 PM** → Q&A and group discussion * **7:00–8:00 PM** → Networking & contact sharing ⚡ Please hold networking until after the presentation so we can all learn together.
