I'd be more curious to know what these SSH scanner bots actually do if they manage to log in. Automated recon, install spambot/cryptominer/phishing site, something else?
replyLast time I saw this an obscure single letter root password was still "secure", now days seems like almost all non-alphanumeric chars works. % is my new root password it still has not been brute forced.
replyNo "credentials" are being "harvested" here. It's all worthless data, save for the statistics.
replyHaving a root password of "toor" is very clever. Nobody will figure that one out.
replytoor was a default password for many devices for decades.
replyI've used unix-like OS's for 28 years and I don't remember coming across it as a password.
replyIt is a common username (see: https://en.wikipedia.org/wiki/Toor_(Unix) ), the machine I am typing this on has it.
It was the default password for the root user in Kali Linux for a while.
replyBack when it was called Backtrack if my memory serves right. I remember being puzzled that it was not the case anymore one day and they even switched to regular user around when Kali became a thing
replySlackware used it in the late 90s IIRC.
replyDid you check out the statistics on the site?
They listed 1233456, 12345, 1234,123 and 1 on the toplist of password.
replyIf we are going to be clever we should follow the statistics and go for 12 that where not on the toplist!!
Or even better, 21. Reverse it to add another layer of obfuscation.
replyYou are right.
reply12 - Rank 318
21 - Rank 523
I'm surprised that '12' is so low on the list.
Do most installations create a git user account with login permissions?
replyThere's no such thing as an account with or without login permissions. Normally you need a git account. And that means you can log in to it. And then you have to try and configure your ssh server so that after logging into the git account, you can only run the git server (I forget the command). If a mistake is made with this configuration then you can log in or port forward or X forward or file transfer as git.
replyThis is a terrible idea because it's blacklist-based security. Places like GitHub have their own ssh server that only runs the git server and nothing else.
I suppose /usr/sbin/nologin is not a thing?
replyThat's a hack. It's a login shell that, once you have already logged in and run the shell, prints a message saying you can't log in or run a shell, and then exits.
replyIt does not stop you from, say, logging in to SSH and then starting a port forward. Or running a command in a way that bypasses the login shell. ssh will always pass it to your login shell but other ways can be vulnerable.
SSH bastions would like a word I guess. You can authenticate, but you definitely can’t login (which is also the case for git over SSH).
