Hey buddy, are you a problem solver and thrive to solve some interesting challenges, if your answer is yes, then here is a challenge for you, “Can you impress Doremon to get a gadget from him”.

Background

Before I give you the challenge let me give you some background about it, technically speaking this is a CTF (catch the flag) challenge put under web category, but for me this is a kind of puzzle that can be solved one step at a time with some technical knowledge (of course! you can use google to get some help and refresh your skills). So the end goal is, you need to find a flag that is in form of CtfFlag{<< flag here>>} by solving the puzzle with multiple twists in it.

Prerequisite

You need to have docker installed in your system, as I am going to give you a docker file that you need to run to get the web application up and running. Once docker is installed on your system follow the instructions to run the application.

1. Pull the docker image from docker hub, you can run the below commands in windows cmd or Linux/Mac terminal.

docker pull satyathinks/dora-app:1.1
