Name: Essentials: Welcome to Linux: Did You Look Everywhere?

Description​

You are given access to a seemingly uninteresting system. ls shows that a file hierarchy is present in the /home/ctf directory. Upon inspecting it, all files seem to be empty.

Score: 100

Exploit​

Running ls -a inside /home/ctf/south-park/al-gore/manbearpig reveals a hidden file called .flag. Inspecting its contents with cat .flag displays the flag.

Use the commands in ./sol/solution.sh.

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.
