Name: Essentials: System Exploration: Empty Files

Description​

The /home/ctf/south-park folder houses a large hierarchy of files. Most of them are empty.

Score: 100

Vulnerability​

Some of the files contain letters. The concatenation of these files, sorted lexicographically, is the flag.

Environment​

Linux container that students can log onto using ssh.

Deploy​

Deployment is done via Docker using the Dockerfile and support files in the deploy/ folder.

Copy the challenge folder to the remote hosting system, enter the deploy/ folder and run make run. This will create and deploy the Docker container with the proper port redirection in place.

If you need to update the image and container, first use make clean to remove the old container, then use make to update the image (and the container). It is not possible to update the container without updating the image first.
