Background: 15 years of experience in software and apparently spoiled because it was already set up correctly.

Been practicing doing my own servers, published a test site and 24 hours later, root was compromised.

Rolled back to the backup before I made it public and now I have a security checklist.

    One time, I didn’t realize I had allowed all users to log in via ssh, and I had a user “steam” whose password was just “steam”.

    “Hey, why is this Valheim server running like shit?”

    “Wtf is xrx?”

    “Oh, it looks like it’s mining crypto. Cool. Welp, gotta nuke this whole box now.”

    So anyway, now I use NixOS.

    And this is why every time a developer asks me for shell access to any of the deployment servers, I flat out deny the request.

    Good on you for learning from your mistakes, but a perfect example for why I only let sysadmins into the systems.

      I published it to the internet and the next day, I couldn’t ssh into the server anymore with my user account and something was off.

      Tried root + password, also failed.

      Immediately facepalmed because the password was the generic 8 characters and there was no fail2ban to stop guessing.
