Hullu is a lightweight vulnerable Alpine Linux VM for cybersecurity education, ethical hacking practice, and isolated lab/CTF-style scenarios.

It includes DVWA, FlaskVA, DNS Lab, BIND 9, Apache, MariaDB/MySQL, phpMyAdmin, SSH/SFTP, and optional FTP/Samba practice.

Hullu 3 adds DNS Lab, BIND 9, FTP/Samba server support, and separate service accounts for Flask-based services compared with Hullu 2.

Use only in an isolated lab network. Do not expose this VM to the internet.
