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.

Yes, every distro requires a password for sudo. That's the whole point of it. But editing .bashrc does not require sudo. You can add aliases and functions to .bashrc. A malicious script can append to .bashrc, and by doing so, it can alias sudo to be whatever command it wants. For instance, a malicious function. So the next time you run sudo it runs the malicious command, instead, which itself can act just like sudo and prompt you for your password. So now you just entered your password into a malicious function. Do you see the problem with this?
Then lock bash rc as read-only and root permission only, or disable aliasing altogether I guess
