If you want a bunch of stuff that's not in core or extra and you don't want to intensely babysit the AUR, you could try Chaotic-AUR. It hosts prebuilt packages for a bunch of AUR packages which are actively maintained by the Chaotic team.

I consider it to be more secure than the AUR proper since they actually care for their packages and review nontrivial changes. For instance, the recent takeover attacks didn't hit Chaotic-AUR builds since the changed packages didn't make it past the review.

It's still an unofficial third-party repository and closer to the AUR than to extra but I consider it a major step up.

I mean how often do you install AUR packages? Usually takes like a minute or so to skim through PKGbuild and the pkg comments and look for obvious issues. And most updates are just a sha hash and version change, taking like 5s to check.

I wish I could give you a second upvote, that's hilarious 😂

Well earned upvote, sir/ma'am.

This video taught me a lot.

Check the list of dependencies. If you really want to vet the package, look through all of the dependencies listed and read their package descriptions on their source page (github, gitlab, codeberg, whathaveyou). Check also the URL, from which makepkg (or yay or whatever) is going to pull some of the data. Is the URL legit?

as the other commenter said, but worth echoing:

• is it suddenly using npm to install/run something? (iirc this was the attack vector for most packages that were infected)
• suddenly added some weird extra wget/curl/whatever to packaging methods to fetch something weird?
• are the package's sources (eg. github urls) legit?

Generally you should be aware of who'se software you're installing -> check if it's downloading the stuff from right place, and nothing extra. The PKGBUILD changes in the aur website are pretty good indicator if something has changed and how.

edit: npm itself, or it's usage isn't bad - but it is quite suspicious if the AUR package isn't for some webapp or so.

Suddenly an npm command to some random package appearing in an update

I think that the whole concept of sharing user repos to install packages is sadly not really good anymore. Because now it suddenly exposes that there is usually neither a trust anchor to that repo, nor an established review and fix process for such things.

I‘d say, just use the community maintained official package sources for now.

Get AI to read it, it'll be 90% good enough

My dumb ass

Yeah same. Aur has been significantly less virus prone than the windows norm (inb4 wut abut winget >;ppp) of "Googling some shit you want and clicking the first website to roll the dice on predatory ads or malware or maybe the thing you wanted"

...not to mention if you have btrfs you can just rollback a month or two and call it a day.

This is more important after the recent news of malware on AUR

Yeah, I just update all 20 flakes that I sourced from github and pray that none of them were hacked

/s (nix just hasn’t been targeted yet (as far as we know 💀💀))

Isn't the real security through obscurity just being such a fringe market no one bothers? 🤔

Sorry I missed something, how so?

Distrobox is not an isolated environment, it is quite the opposite. They say so themselves on their page:

Security implications

Isolation and sandboxing are not the main aims of the project, on the contrary it aims to tightly integrate the container with the host. The container will have complete access to your home, pen drive, and so on, so do not expect it to be highly sandboxed like a plain docker/podman container or a Flatpak.

I would argue that Docker isn't a good way to stop malware either, since it is highly vulnerable to sandbox escape leveraging the shared host-guest kernel, like the many of LPEs that have been found in the last few months (example using copy-fail).

Docker is not a secure sandbox, Podman is not a secure sandbox, Flatpak is not a secure sandbox. Use a VM, or better yet, don't use the AUR.

I use arch just to be able to use AUR lol
