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.
Interesting. Do you know how it got compromised?
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.
wow crazy that this was the default setup. It should really force you to either disable root or set a proper password (or warn you)
Most distributions disable root by default
Which ones? I’m asking because that isn’t true for cent, rocky, arch.
Mostly Ubuntu. And… I think it’s just Ubuntu.
Ah fair enough, I know that’s the basis of a ton of distros. I lean towards RHEL so I’m not super fluent there.
we’re probably talking about different things. virtually no distribution comes with root access with a password. you have to explicitly give the root user a password. without a password no amount of brute force sshing root will work. I’m not saying the root user is entirely disabled. so either the service OP is building on is basically a goldmine for compromised machines or OP literally shot themselves in the root by giving root a password manually. something you should never do.
Yeah I was confused about the comment chain. I was thinking terminal login vs ssh. You’re right in my experience…root ssh requires user intervention for RHEL and friends and arch and debian.
Side note: did you mean to say “shot themselves in the root”? I love it either way.
