SHELLGym

ABSTRACTSHELLGym 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 Forensics, logs, system artefacts The session will be about examining baseline Linux systems, investigating how user activities (and intrusions) are logged. We will also examine basic Linux OS functionality such as cron and other simple services (eg, SSH) and how their activities are logged. Similarly, we will look at configuration files can alter the way some services behave, as configuration files are also targets for attackers to alter. Crafted scenarios could include some basic triaging and log analysis (little to no RE), with some added complexity where an attacker manages to tamper with logs to mislead forensic teams and would-be investigators. Participants will have some hands-on activities to collate artefacts, parse them, and identify potentially suspicious actions within. ⚠️ NOTEBring your own laptops (and laptop chargers).

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.
