You could even replace every command I run with a malware version simply by altering the $PATH in ~/.bashrc. If you manage to replace, say, apt-get with a malware version, you'll get admin permissions every time I run `sudo apt-get ...`.

If your sudo is configured correctly it will have an administrator defined PATH. However if you have sudo price to run apt-get, anything that could manipulate your rc files can just run sudo apt-get on its own. No need to trick you.
