Deck of Cards CTF
I created a small crypto style CTF for Black Hat last year (we’re training again this year, check our courses out) and hid the starting point in an “easter egg” on a deck of cards. The deck of cards are a custom design by the SensePost training team, which were themed around hacking and were handed out during the conference. This post covers how we built it, and how to solve it.
Black Hat Card Deck CTF
In 2023 we, the training team within Orange Cyberdefense and specifically Ulrich Swart, Matthew Hughes and myself, attempted to do something a little different for Black Hat with regards to our in class competition. Each year we give a select few students some swag for portraying the most “plakker” mindset, being active in class, or finding another method to solve the practical.
The concept we decided to explore that year was creating a deck of standard playing cards they could bring out when friends are over and become a discussion point. The cards have educational tidbits about some material they will learn on some of our flagship courses, specifically the Infrastructure, Web Application, Wi-Fi and Red Team courses each had their own suit.
Exploring The Fundamentals
We are excited to be presenting our Hands-on-Hacking Fundamentals (HHF) course at this year’s BlackHat USA 2021 conference. In our HHF course we explore the fundamentals required to grow your hacking skills where you can utilise your newly learned skills with practical, real world hacks in our custom lab environment. This blog aims to demonstrate the fundamentals of networking and scanning using the defacto Network Mapper “Nmap” which is one of the many tools utilised in our course.
Hack-From-Home Challenge Walk Through
On the 27th of April 2020 SensePost created a CTF challenge (https://challenge.sensepost.com) for the public. The names of those who managed to capture flags would be placed in a draw for a seat on one of SensePost’s upcoming training courses. The challenge was to grab as many of the four flags as you could. Each flag was harder to get than the previous. Engage the brain. The challenge started with a simple engage the brain ctf, where we needed to try guess the next page value by looking at the clues on the current page.
