⚠️ **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)

**For ages 13 and above.** IKMF Krav Maga training helps you defend yourself effectively on the streets. Below are just some of the reasons why Krav Maga classes at IKMF Singapore will benefit you. 1\. There are no rules in street attacks\, so imagine what we will do to the attacker\. 2\. No one wants to get in a fight\, so prevention & de\-escalation will be taught too\. 3\. You're lucky if there's just 1 attacker out in the streets\. To better prepare yourself\, we train with the mindset of potentially facing multiple attackers\. 4\. Did I mention weapons? Who says attackers can't possess knives/sticks/guns? ### **Address** 767 Upper Serangoon Rd, #01-05, 534635 Singapore (Kali Majapahit Martial Arts studio) ### **Schedule** Saturdays 4PM - 530PM ### **Booking Information** * Please contact **98225900** to find out how to book this class. * The instructor will reach out to you once you've booked the class.

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.
