So if I have my computer set that it needs a sudo password for most changes am I good?
Yes, that’s my understanding. A normal user cannot do this. (And of course, an attacker shouldn’t not control a local user in the first place.)
Physical access is also a risk, but physical access trumps everything.
Thanks for the answer. Unless my dog learns how to code I think I’m safe from anyone getting physical access
As a hacker imma start teaching dogs to code as part of my breakin process, sorry bud
