I don’t use CachyOS nor do I know anything about their team and I haven’t used the script either. My point was just that I would trust OS maintainers more than some random guy on the internet.
I have checked again and it seems the script I was referring to was actually from a mod on their community forum. Not sure if this is a maintainer as well or not.
My point still stands, if you trust the source and checked the code that nothing shady is going on, it is perfectly fine to run a script. Even if it is just an additional check after you cleaned it manually. Maybe you have missed something.
You are right that the distribution as it provides binary code is a trust root. If you can’t trust them, you have nothing to stand on.
I had the impression that CachyOS suggests to use AUR packages - maybe I am wrong here?
And if CachyOS is (what I am just assuming) geared towards less technical users, can you really expect their average user to examine shell scripts from a forum post?
How do their users even know that the post and its author is legitimate? Are they supposed to check PGP keys?
I have no idea about the stance of CachyOS on AUR packages.
I totally agree with you, establishing trust is not an easy problem. I don’t expect the average joe to understand shell scripts. I would put myself in that categorie as well. This one however was simple enough that it seemed okay to me. If I don’t understand what’s going on in a script I am really careful and try to avoid it, if possible. I still wouldn’t consider them universally bad. For some things it is even the recommended install option. I vaguely remember some things in the Raspberry Pi universe ( IIRC this was even the case for Docker in the past).
There are multiple factors which can lead to trust. Maybe you know the CachyOS forum and how well it is maintained. How old is the account etc…
But as you said, there are always risks. The account could be compromized as well. But most of that isn’t specific to shell scripts or Linux in general. You shouldn’t install an application from some shady website in Windows either.
What is your recommended way to deal with the current situation?
I appreciate your effort and really enjoy the discussion. Most of your suggestions are probably a good idea for the future, but they are not really a solution for a potentially infected system right now.
You can pull out the big gun as well and purge all AUR packages entirely or even reinstall your system, but their might be an easier solution.
What do you think this does, in bash:

Without looking it up, I wouldn’t have had a clue. It looks somewhat purposefully obfuscated but used in the right context, I am not sure I would have picked up on it. Maybe you are right and I should reconsider my approach.

You can call that paranoid but there is a reason why distributions use packkage signing, publish webs of trust, and why the Guix developers even worked hard to reduce the binary bootstrapping code for the distro down to 512 bytes - it is a consequence of the “trusting trust” problem posed by Ken Thompson that the more stuff is opaque, the more trust is needed.
