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.
You must log in or register to comment.
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.
Good point about a default deny approach to users and ssh, so random services don’t add insecure logins.
