Fun with SANS Holiday Hack Challenge 2019
Updated: May 24
Our Feb 2020 monthly meetup was cancelled due to the developing COVID-19 situation. But we'll never let a good sharing go to waste. Our Feb 2020 monthly meetup speaker — Law Che Lin — shared the fun he had with SANS Holiday Hack Challenge 2019 last Dec at our newly founded Div0 Digital Meetup.
Che Lin picked 5 challenges he found particularly interesting and walkthrough his challenge-solving process.
The 5 challenges Che Lin walked the Div0 crowd through were:
Challenge 2: Unredact Threatening Document
Challenge 4: Windows Log Analysis: Determine Attacker Technique
Challenge 7: Get Access To The Steam Tunnels
Challenge 9: Retrieve Scraps of Paper from Server
Challenge 10: Recover Cleartext Document
You can download a copy of Che Lin's presentation slides [here].
There were countless moments many of us went "how did he think about that to solve the challenge!?". Che Lin reminded the Div0 crowd that the actual challenge-solving process was, and never will be, linear as his polished walkthrough.
Cybersecurity is a challenging field, and resilience is an important trait cybersecurity practitioners must possess to succeed.
A big shout-out to our co-host ICE71 for hosting our Digital Meetup.
