Scratch It Out

CTF: Angstrom 2019

Category: misc

Difficulty: Easy

Description

---

An oddly yellow cat handed me this message - what could it mean?

address : https://2019.angstromctf.com/challenges

Solution

---

In this misc challenge we just have a JSON written in a file.

This JSON is made up as follow:

{
	"targets": [...],
	"monitors": [...],
	"extensions": [...],
	"meta": {...}
}

I confess that the challenge includes a bit of guessing. But the name of the challenge, the yellow cat in the description and the monitors field in the JSON makes me mind about Scratch and in fact the JSON file is a Scratch project.

Basically load this file in the Scratch web page and run the sprite.
