About Event

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
⏮️ Linux RE and exploitation

So you've found some weird "malware" on your Linux server and don't know what it does? Or maybe you managed to segfault some program and want to try to exploit it? Or maybe you just play CTFs. Either way, this month covers reversing Linux-related binaries, and potentially pwning them. It'll cover the basic tooling required and the mentality it takes to dissect a Linux binary. Crafted scenarios could include "simulated malware" that demonstrates actual malware techniques, but in a benign way. It could also include deliberately vulnerable software, designed to teach some exploit techniques or data structures that could be corrupted by exploits.

⚠️ NOTE
Bring your own laptops (and laptop chargers).

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.
