Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

What does a trojan look like when it has over 900k+ combined installs and a Forbes write-up? Exactly like a legitimate Chrome extension. This session presents a technical dissection of two Chrome extensions, each with over one million active installations — that functioned as trojans in production environments, evading detection while operating through entirely legitimate browser APIs. These were not obscure tools. They were widely trusted, actively recommended, and covered by mainstream press before their malicious behavior was fully understood. We will walk through the actual source code of both extensions, showing precisely how the malicious functionality was constructed, concealed, and executed at scale. This analysis anchors a broader examination of how modern compromises actually succeed. Drawing on aggregated real-world incident data, we identify the technique categories currently delivering the highest adversary return, and why they keep working. Spoiler: it's rarely a zero-day. It's trust. The Chrome extension deep-dive will cover: * Line-by-line source analysis of how malicious functionality was embedded within working, useful software * Which browser permission scopes were abused, and why a million users — and their IT teams — didn't see it coming * The behavioral and structural indicators that distinguish a trojan extension from a legitimate one, and how to operationalize detection around them This session closes with a practical defensive prioritization framework built around observed attacker behavior: which mitigations are measurably reducing risk in production environments, which are consuming budget without impact, and a scoring methodology your team and leadership can apply immediately. **Source material:** Primary analysis of extension source code, corroborated by reporting from Forbes and other established outlets. **What this is not:** A vendor pitch, a speculative threat narrative, or a surface-level breach retrospective. **Who should attend:** Security architects, AppSec and cloud security practitioners, blue team leads, threat hunters, browser security practitioners, and security leaders responsible for prioritizing risk and investment decisions.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
