SHELLgym — 12 Ways to Inconvenience Your Life for Security
Details
⚠️ REGISTRATION IS REQUIRED VIA THIS SIGN UP FORM ⚠️
ABSTRACT
On the 12 days of christmas, SHELLgym gave to me: 12 tips to improve cybersecurity!
Except that we don't have 12 days (just 4 hours).
And every one of those tips aren't really "gifts" because they will inconvenience you in some way or another.
So avoid Big Santa's ability to collect your PII and pop down for a grinchy session of SHELLgym on 20 December 2025.
⚠️ NOTE
Bring your own laptops (and laptop chargers). VMs optional.
TRAINER
KK Tan — Founder, counterShell
As a mid-careerist convert to cybersecurity, Tan KK 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, KK 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.
