Why disable ssh login with root on a server if I only log in with keys, not password?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Also double check that sudo is the right command, by doing
which sudo. Something I just learned to be paranoid of in this thread.Unless
whichis also compromised, my god…which sudowill check$PATHdirectories and return the first match, true. however when you typesudoand hit enter your shell will look for aliases and shell functions before searching$PATH.to see how your shell will execute 'sudo', say
type sudo(zsh/bash). to skip aliases/functions/builtins saycommand sudomeh nvm none of these work if your shell is compromised. you're sending bytes to the attacker at that point. they can make you believe anything
Maybe if you escaped the command like
\\type sudo?no, if the attacker can change files in your account, they can read every byte you type in and respond with anything, including pretending to be a normal shell. im not sure how to prevent ssh from running commands in your shell
You assume the shell isn't compromised.
