⚠️ **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)

**Connected Westerville Night of Networking** *April Edition: The Introduction Economy* You've been to the networking events. You've done the small talk. Collected the cards. Forgotten the names. And walked out feeling like you just wasted two hours of your life. The problem isn't you. It's the format. Most networking events put you in a room and tell you to figure it out. So everyone defaults to elevator pitches and business talk, and nothing real gets built. Here's the truth about networking that most people miss: Your network isn't just who you know. It's who thinks of you when they're talking to someone else. *That's* The Introduction Economy. And it only works when relationships are real. There's a reason people who come once keep coming back. It starts with seven minutes that feel nothing like networking. Then we open it up. Free networking. More conversations. More momentum. This is a room full of corporate professionals, entrepreneurs, business owners, creatives, and career builders in the Westerville and Columbus area. The mix is the magic. You might never do business with everyone you meet tonight. But someone in this room will think of *you.* **By name**. So, the next time someone needs exactly what you do, you get the recommendation. **April 14th. RSVP now.** **When:** Tuesday\, April 14th \| 6:15 PM \-\- 8:00 PM **Where:** Vineyard Community Center \| 6000 Cooper Rd\, Westerville\, OH 43081
