This repository is training material. The lab is designed to run on a single machine: every port binds to 127.0.0.1, and the credentials in labs/ are public, lab-only values. Do not expose the lab to a network and do not reuse its passwords.

If you find a security problem — for example a script that could expose a student's machine, or a lesson that teaches an unsafe practice without saying so — e-mail connect@moitoi.tech with the details. Please do not open a public issue for it. We aim to reply within five working days.
