⚠️ **REGISTRATION IS REQUIRED VIA [LUMA](https://luma.com/7adqd4e9)** ⚠️ **ABSTRACT** SHELLgym is the regular cybersecurity workout you have been looking for! Whether you're just starting out and need some exercises, studying for a cert (hint: OSCP), looking at CTF challenges, or developing something cybersecurity-related (maybe your own automated tools?), SHELLgym aims to help you progress in picking up practical cybersecurity knowledge and skills. Come and go as you please, work on your own stuff with like-minded individuals, or just have fun during the workout! **AGENDA** Getting and using shells. Finally, a topic in SHELLgym that covers shells! For this session, we'll talk about remote access, from exploits versus payloads, to simple persistency. Then, we'll do some triaging and threat hunting to detect such shells in our environment. The session will roughly follow this sequence: 1\. Remote access: bind/reverse shells 2\. A simple\, traditional killchain from exploit to payload to persistency 3\. Getting inspired by MITRE TTPs 4\. Threat hunting **⚠️ NOTE** Requirements: a computer, so that you can connect to the network, administer your shells, and enjoy a more interactive hands-on experience. **VIRTUAL SHELLgyms in APRIL** (by request) Hosted on Discord, do approach KK or the Div0 Crew for access ! **TRAINER** **KK "Jim" Tan — Founder, counterShell** As a mid-careerist convert to cybersecurity, **Jim** picked up his practical skills through getting OSCP certified and by participating in a variety of CTFs. In his career at CSIT, he performed a variety of red-teaming and vulnerability research roles and established the Cyber Training School at CSIT as the Lead Instructor. Besides the OSCP certification, Jim is also OSCE and OSEE certified, and has a Bachelor's degree in Social Science (Psychology). He now sees psychology as a field of study where you fuzz humans until they produce unexpected behaviour. **SPONSORS** * VENUE SPONSOR: [CyberSG TIG Collaboration Centre](https://www.linkedin.com/company/cybersg-tig-collaboration-centre) **IMPORTANT NOTICES** * Code of Conduct: [https://www.div0.sg/code-of-conduct](https://www.div0.sg/code-of-conduct) * Terms of Use & Disclaimer Notice: [https://www.div0.sg/terms-of-use-disclaimer-notice](https://www.div0.sg/terms-of-use-disclaimer-notice)

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

The market changed—and most investors are still operating like it didn't. Deals that used to work don't. Buyers want different things. And a lot of what's being taught right now is outdated or just wrong. And, since 2011, it's been our job to make sure that our members are armed with the most up-to-date, real-world strategies for building wealth in Central Ohio real estate… …so our mission with this meeting (and every meeting) is to give you the no-hype, warts-and-all info you need to succeed. First, Wholesaling 101—a clear, real-world look at how wholesaling actually works today, what to pay, and how to stay out of trouble. Then, Creative Deal Autopsies—real investors breaking down real deals with real numbers, real conversations, and real outcomes. You'll also get the chance to put the presenters in the hot seat and ask any and every question you have about how they did their deals. You'll learn: 1. What wholesaling actually is 2. How to calculate real offers 3. Where deals are coming from now 4. What buyers want 5. How creative deals are structured 6. What contracts and terms are used 7. What can go wrong—and how to avoid it **Agenda:** 5:00–6:00: Free Light Dinner and Networking 6:00: Earlybird Meeting – Wholesaling 101 7:00: Buy-Sell-Trade (members only) 7:30: Creative Deal Autopsies Members: Free First-time guests: Free Non-members: $35 (or join for $30 instead) Remember, to actually reserve your seat, you have to go **[HERE](https://www.coreerocks.com/Events.aspx?ID=IN-PERSON-in-Columbus-Creative-Deal-Autopsies-Wholesaling-101-14-4-7-2026)** and register on our website!

AI is changing how art is made. But when does it stop being your work and start being the machine’s?

We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)
