God, even the Arch malware uses npm as a vector. And thus, my hatred of npm deepens even further

Tbf, it is run in package post install section so it could be anything even the typical "curl malware.om | bash". There is a new wave of attacks now pulling things in with Bun which i guess is similar thing to NPM
I'm just a web guy whose tired of installing 10 xetabytes of 2 line libraries every time I wanna check out anything web related
What can be done to prevent this from happening to the AUR?
The AUR is kind of a trap. It can be useful but it has the warnings it has for a reason. Maintainers are not vetted so you depend on them both to be benevolent and competent and neither are reliable.
No one should really use it without taking the time to understand pkgbuild but you have people recommending AUR helpers like yay and tying AUR updates to regular system updates which is a terrible idea
paru always shows you the diff of the PKGBUILD on upgrade, so no need to worry about adding it to an alias that does both.
In fact, just running paru is the same as running
pacman -Syu
paru -Sau
At the end I review the PKGBUILDs and make sure everything looks reasonable. Usually it's just new source hashes, but not every time.

The way to prevent it is to get more stuff into the official repos so people aren’t forced to rely on AUR in the first place.

in theory? getting rid of paru and friends, manually reviewing the pkgbuild and the source of whatever it is installing
realistically? nothing. the AUR is a glorified repository of build scripts anyone can upload. the script or the package itself can ship malware
the AUR is mostly the same as downloading and running random exes on windows. you should avoid it, make it as manual as possible (forcing you to double check what's happening) and be able to review the installer/package or trust someone who can vouch for its safety
paru shows you the PKGBUILD diffs on upgrade, so you can review then and deny upgrades.
But realistically I am not going to go into the code itself on my installed packages to check for malware or other types of attacks. That's too time consuming for my risk level, and requires more knowledge than can be expected, to be honest.
Edit: but maybe you're talking about when first installing a package? Come to think of it, I'm not sure it shows the PKGBUILD at that point. 🤔

The AUR is unsafe by design. It's not intended to be something you just install from willy-nilly. It's intended to be a helpful way for arch users who know what they're doing to exchange a convenient way to install arbitrary packages. But you should always be just as wary of it as copy/pasting shell code from a random person on the internet.

Ah yes, review the PKGBUILD for every AUR update. Luckily I do this while I'm rereading the ToS every time those get changed for all my software as well.
When I finish that I intend to read the changelog in git for each of the commits since the last update.
I always check with my contract lawyer before installing or updating from the AUR. It's worth it for me.
Trying to escape surveillance capitalism while installing aur packages willy-nilly.
Are you one of the malicious actors? Thats some shit I'd expect to hear from the people doing this, trying to justify the attack by blaming the users for "capitalism".
I am quite confused by your assumptions. I am just making a joke about people trying to avoid surveillance capitalism tools on one side and gleefully installing aur packages from random people on the other side, potentially making their surveillance exposure worse. I'm part of them some time because it's too hard to verify everything everytime.

i can empathize with those infected but it's important to note that the source of this issue is still installing random stuff from random people. the aur is not the same as arch repos, and users wanting to opt in need to take more precautions than usual

~~Users can check if they're already compromised with pacman -Q | grep alvr I think maybe?~~ EDIT: No, sorry, alvr was just one of countless affected packages. Also, several is an understatement since a huge number of packages are affected.
Post with more information here: https://lists.archlinux.org/archives/list/aur-general@lists.archlinux.org/thread/FGXPCB3ZVCJIV7FX323SBAX2JHYB7ZS4/
alvr as in the vr streaming program for standalone headsets? that's kind of a niche among niches. Linux VR users with standalone vr headsets that use that specific method.
Sweats in “linux vr is one of my current hobby projects”
I panicked a bit when I saw the news earlier today as one of those niche guys. Then remembered I had removed it for WiVRn a few weeks ago and don't have anything else off the AUR. Double niche win lol
EDIT: No, sorry, alvr was just one package, there is no specific source for the infection just one or many malicious users: https://gr.ht/aur_pkg_list.txt

Oh my, I'm new to Linux and I use CachyOS for my gaming rig at home. Most of the time I have no idea what I'm doing, but shit runs well and I'm happy about it. But how the hell do I check my noob ass if it's compromised?!

Hilarious that it's JavaScript again, truely npm, pypi and cargo are obvious targets. Also, guys, minimise your usage of the AUR! I don't use any AUR packages.
Core > Extra > flathub >>>>>>>>>>>>> AUR
Not that core/extra/flathub can't be pwned but it's harder then the AUR.

Here’s a incomplete list:

I know some on Lemmy here use the RuneScape launcher.
For an automated script to help you check, you can use https://github.com/lenucksi/aur-malware-check to see if you're infected.
Very useful, thanks.
Came up clear, fortunately.
Out of curiosity, did Arch send any notifications through pacman or anything? The first I heard of this was on Lemmy.
I miss the browser, but luckily I haven't played RS since the new CEO cancelled new Pride Events right after the Trump Admin was reelected.
This reminds me to remove the Fluxer AUR package I have
yikes, I'm glad I decided to switch to debian stable recently, not that it's a foolproof system either
