How Claude-powered systems actually get hacked. We'll go straight into the attacks people are running right now: prompt injection, jailbreaks, agent and tool exploits, and what red-teaming the Claude ecosystem really looks like. 🍕 **18:00 – 18:30** · **Gathering, Pizza & Drinks** 📣 **18:30 – 18:45** · **Welcome + Latest Claude Updates** · Organizers 💻 **18:45 – 19:15** · **JavaScript Is All You Need: Exploiting Agentic Workflows for API Key Theft** · Eden Katz, GenAI Security Tech Lead @ Alice. Building with AI APIs? This one matters. Alice's research shows that API key creation on platforms like Anthropic relies on cookie-based auth alone — so a malicious browser extension or a compromised agent skill can silently mint a new key and ship it elsewhere. No MFA, no warning, no expiration. As agents get trusted with autonomous code execution and client-side access, the line between safe tool use and serious vulnerability collapses. JavaScript really is all you need. 👾 **19:15 – 19:45** · **Securing coding agents: Unpacking Threats and Defences** · Bar Kaduri, Principal researcher @ Capsule Security *AI coding agents like Claude Code, Copilot, and Cursor now write, execute, and ship code with unprecedented autonomy, often straight to production. But this privileged access opens a unique attack surface, as recent incidents like prompt poisoning and deleted databases reveal. This session breaks down the real-world threats facing coding agents and delivers practical, actionable defences for securing your AI-assisted development pipeline.* 🍻 **19:45 – 20:00** · Drinks & Geek Out

***[IMPORTANT NOTICE registration is HERE](https://luma.com/j8czeuvr)*** Join **Aerospike, Start.io, and Contentsquare** for an evening of deep technical talks and peer-level discussion on the real trade-offs behind operating modern real-time systems in production - where tail latency, throughput predictability, scalability, and cost efficiency are constantly in tension. This event will move past theory and into hard-earned production lessons: scaling beyond RAM constraints, migrating high-throughput workloads from Redis to Aerospike, designing architectures driven by real cloud cost models, and uncovering the non-obvious pitfalls of migrating real-time systems from AWS to GCP. Topics range from VPC architecture and traffic steering differences to NVMe and local SSD behavior, and why familiar operational playbooks often fail across clouds. This event is designed for engineers and architects already running latency-sensitive, high-scale systems - where milliseconds matter, growth is relentless, and infrastructure decisions directly impact performance, reliability, and cost. ​ **Agenda** **​17:30 – 18:00 - Welcome drinks & networking** ​**18:00 – 18:10 - Opening Remarks – Speed vs Capacity: Designing Data Systems for Real-Time Scale** *Oshrat Ben-Avi Zabludovitz, Israel Country Manager, Aerospike ​* **18:10 – 18:30 - Scaling Past RAM: Architecture Lessons from Our Redis-to-Aerospike Migration** *Ilan Huchansky, Data Platform Team Leader, Start. io* ​As Start.io scaled, our legacy Redis-based architecture for the user-profiles database reached significant operational limits, particularly during high-traffic periods, node failures, and scaling events. To maintain our strict performance SLAs while reducing operational overhead, we embarked on a search for a more robust, cost-effective NoSQL solution. In this session, we will share the architectural lessons learned while evaluating the database landscape - including our comparisons with alternatives - and our ultimate migration to Aerospike’s Hybrid Memory Architecture. We’ll discuss how we moved past RAM constraints to achieve sub-millisecond performance at massive scale without compromising on availability or data consistency. ​ **18:30 – 18:50 - Boosting Cost Efficiency with Cost-Aware Architecture** *Doron Hoffman, Chief Architect, Contentsquare* ​ In this session, we explore the critical role of cost-aware architecture in achieving optimal cost efficiency for modern software systems. As organizations increasingly rely on cloud services, microservices, and distributed computing, understanding and managing costs becomes paramount. ​We’ll discuss the shift from traditional architecture to cost-aware design and examine how architectural decisions directly impact operational expenses. Through a real-world example, we’ll share lessons learned from evaluating multiple cloud providers and their services using cost models and how rearchitecting with cost as a first-class concern made a measurable difference. ​Attendees will gain practical insights into designing cost-efficient systems that balance performance, scalability, and financial constraints, enabling more sustainable growth. ​ **18:50 – 19:10 - The Latency Leap: Hard Lessons in Migrating Real-Time Systems from AWS to GCP** *David Gerchikov, Senior Software Engineer, Aerospike* ​ Moving a stable web application between clouds is challenging; migrating a high-throughput, real-time system is far more delicate. When heartbeats are measured in milliseconds, the “invisible” differences between AWS and GCP—from VPC architecture to NVMe and local SSD behavior—can determine whether a migration succeeds or fails. ​This session goes beyond basic service mapping to explore the real friction points of moving a real-time engine from AWS’s regional model to Google Cloud’s global fabric. We’ll cover networking and traffic-steering gotchas, why AWS operational playbooks often don’t translate, and how storage lifecycle constraints in GCP Local SSDs force changes in node management to preserve predictable performance and reliability. ​ **19:10 – 20:30 - Networking and fun** ***[IMPORTANT NOTICE registration is HERE](https://luma.com/j8czeuvr)***

This meetup is an advanced one! We will be presenting all sorts of complicated networking, identity, AI and platform engineering solutions established on AWS infrastructure! **What To Expect?** * **Pizza and beer!** * **Cool Swag** * **Awesome Speakers** **Agenda:** 18:00-18:30 **\- Networking\, beers and pizza** 18:30-19:00 **\- Talk 1:** **AI didn’t Wait for Security - Now What?** Speaker: [Ran Isenberg](https://www.linkedin.com/in/ranbuilder?utm_source=share_via&utm_content=profile&utm_medium=member_ios) , AWS Hero & Principal Architect @Palo Alto Networks & [Stav Ochakovski](https://www.linkedin.com/in/stav-ochakovski?utm_source=share_via&utm_content=profile&utm_medium=member_ios) ,AWS Hero & Senior DevOps Engineer, Eon. AI didn't wait for your security review. Developers are already using agentic AI, coding assistants, agentic skills, and MCP servers to write, review, and ship code, often without shared security standards or governance. In large orgs, this becomes chaotic tool sprawl: multiple IDEs, many agents, inconsistent rules, and rising risk. The instinctive reaction is to block AI tools entirely. That approach fails fast: developers work around it, security loses visibility, delivery slows, and risk grows. This talk offers a better path: treat AI as a first-class platform citizen. Drawing on platform engineering principles, you'll learn how to build centralized MCP guardrails, a curated agentic skills catalog, and reusable agentic blueprints, backed by AI SDLC frameworks that govern AI usage while accelerating delivery of AI-powered services. 19:00-19:30 **\- Talk 2: No Secrets Attached: AWS as Your OIDC Provider** Speaker: [Omer Cohen,](https://www.linkedin.com/in/omercohen?utm_source=share_via&utm_content=profile&utm_medium=member_ios)Head of Security, Descope Stop putting secrets in Lambda. This talk shows how to use AWS IAM outbound identity federation so a Lambda function can mint a short-lived JWT with sts:GetWebIdentityToken, verify and inspect it, and use it to authenticate to Snowflake, MongoDB Atlas, and a cross-account API Gateway. You will leave with a practical architecture, working code, and a clear understanding of where this pattern shines and where the integration edges still are. Hosted by Descope

The topic for July is "Shoes" Speak Easy: true stories, told live. The idea is simple: an audience, an open microphone, and great stories. Hilarious, gripping, poignant- it's up to you. Audiences are invited to come to listen or come to tell as folks from all corners of Columbus offer their stories live on stage! Held at Wild Goose Creative's warm, intimate space, this night of tales occurs on the 3rd Thursday of every month. Doors open at 6:30 pm, show starts at 7:00 pm. Please arrive early if you want to tell, as we generally only have room for a limited number of tellers, and the sign-up sheet has a tendency to fill up fast. Formed around the idea that people need stories--they're what hold and draw us together--SpeakEasy celebrates the strangeness and commonness of being human. And in a world of smartphones, Facebook, Twitter, and more . . . it gives people a real, breathing, in-person way to connect. The night is geared for true stories of all kinds, taking the best tales told around kitchen tables, in darkened pubs, on the street corner, and at late-night parties and giving them an audience. Speak Easy is also a great outlet for performers, writers, and artists looking to share their favorite stories and perfect their skills. We strongly encourage tellers to please tell the story rather than read it so we keep within the spirit of good storytelling and stay engaged with the audience. All are welcome. Hang around after the show for a drink and build community!
