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.

And how would you not be able to hijack the password when you have control over the user session?
You would have to know the root password.
With aliases in the bashrc you can hijack any command and execute instead of the command any arbitrary commands. So the command can be extracted, as already stated above, this is not a weakness of sudo but a general one.
You would have to KNOW the root password.
No you can alias that command and hijack the password promt via bashrc and then you have the root password as soon as the user enters it.
No, that's not how it works.
You really should stop talking shit about things you know nothing about.
Truly sad.
As root:
Anything else?
There are many ways to harden against it, but "just disable root auth" is not really it, since it in itself does not add much.
So, you learned about .bashrc today, and you're now an expert?
Perhaps stand down and let the experts have their say.

Seriously - if you're "advising" on linux best practices, get lots of liability insurance.
