alt Hacker NewsWell, let's say you weren't on a machine with hundreds of users. Let's say you were on your own machine (either as a solo dev, or on a personal - that is, non server - machine at work).
Now, does that machine have any important files that are world-writable? How sure are you? Probably less sure than for that machine with hundreds of users...
If you're not sure if there are any important world-writable files, then just check that? On Linux you can do something like "find . -perm /o=w". And you can easily make whole dirs inaccessible to other users (chmod o-x). It's only a problem if you're a developer who doesn't know how to check and set file permissions. Then I wouldn't advise running any commands given by an AI.
