I am working with Ops Tech Alliance on developing security challenges for the President's Cup, Season 6. The entire repository of PCCC challenges and their solutions can be found on GitHub: https://github.com/cisagov/prescup-challenges
Below are the now publicly available challenges that I developed for the competition.
My first challenge. It was inspired by a vulnerability discovered in the Nissan Leaf several years ago.
A straightforward web exploitation challenge. The challenge involves exploiting several vulnerabilities on a fake social media site.
A web challenge using simple vulnerabilities, but with small caveats that add a lot of complexity. Includes SQL Identifier Injection!
An ICS challenge that tasks you with using an OPC UA server to defend several Modbus devices
A Star Wars-themed challenge that tasks you with creating a novel multi-layer HTTP smuggling attack.
A small choose-your-own adventure game written in C. Vulnerable to a buffer overflow attack that allows you to corrupt the va_list struct.
