    If it's endorsed by the project team I might as well. At that point it's the same as downloading from GitHub and if I am in AUR I've probably not found it in standard repos nor flathub.

    Nah, if you really want to live on the bleeding edge you gotta make blindly installing vibecoded junk from shady parts of the AUR part of your workflow

    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.

    [–] NotSteve_@lemmy.ca 5 points 22 hours ago

    I just recently reinstalled since I didn't feel comfortable with how many AUR packages I had and ive been using ChaoticAUR exclusively now. Can confirm that its a great repo

    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.

    [–] HereIAm@lemmy.world 12 points 1 day ago

    But wasn't the latest AUR attack from a dependancy in the pkgbuild? Going out of your way to review all the dependencies as well is not really possible by just skimming through the script.

    [–] NaibofTabr@infosec.pub 1 points 19 hours ago

    Rarely, to be sure. I tried Arch for a bit, but I need a computer that I can actually use to get shit done, that isn't a constant project itself. Even Qubes doesn't require as much effort to keep operational.

    I use Arch without touching this AUR in my latest install. Just use what's in the main package repos or flathub

    [–] unknownman@lemmy.zip 2 points 6 hours ago (1 children)

    I use arch just to be able to use AUR lol

    [–] prole@lemmy.blahaj.zone 1 points 5 hours ago

    You can just make an Arch distrobox to access the AUR

    I usually do, but I don't really know what I should be looking for. What are some red flags?

    [–] akunohana@piefed.blahaj.zone 44 points 1 day ago* (last edited 1 day ago) (1 children)

    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?

    Yeah. There's also some others behaviours to look at.

    Like, does the PKGBUILD install the package on some non-standard location? That's a suspicious behaviour, although it's not an automatic red flag by itself.

    Does it execute arbitrary code or any external script (worse if it's Python, Lua or JS)? That's a HUGE red flag in most of cases.

    Does it (ab)uses of AWK, sed and the like? That's also suspicious in a variety of cases.

    [–] Malix@sopuli.xyz 26 points 1 day ago* (last edited 1 day ago)

    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.

    [–] dwt@feddit.org 12 points 1 day ago

    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.

    Iβ€˜d say, just use the community maintained official package sources for now.

    [–] First_Thunder@lemmy.zip 13 points 1 day ago

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

    All pointing with fingers to AUR, but the issue was (yet again) with NPM.

    [–] chortle_tortle@mander.xyz 4 points 1 day ago* (last edited 1 day ago) (1 children)

    Sorry I missed something, how so?

    [–] MonkderVierte@lemmy.zip 6 points 1 day ago

    The compromised packages load a script from thr net that runs a compromised npm package ("atomic-lockfile" 1.4.2).

    Ok, also a AUR issue. But more so a NPM one, since they have all full moon two supply-chain attacks.

    [–] Solrac@lemmy.world 2 points 20 hours ago

    I was contemplating moving to NixOS, but then another fiasco just happened, masse me question what would one have to lose by switching to Qubes instead, considering the increasingly surveiling internet.

    [–] zitrone@europe.pub 10 points 1 day ago (3 children)

    just use nix instead

    we have super secure mechanisms in place to prevent supply chain attacks

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

    [–] Euphoma@lemmy.ml 4 points 1 day ago

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

    [–] chortle_tortle@mander.xyz 3 points 1 day ago

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

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

    [–] corsicanguppy@lemmy.ca 4 points 1 day ago

    Maslow, is this your hammer?

    [–] Nalivai@lemmy.world 15 points 1 day ago (4 children)

    I'm running Arch daily since 2015, was on Debian before. I install and try a lot of stuff. Never had anything bad happened to me once. Worst case scenario the shit I just installed didn't work so I have to debug it.
    Not endorsing this apparently dangerous lifestyle, but also a little bit maybe

    [–] Funkt4st1c@lemmy.world 5 points 1 day ago

    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.

    I once found a Rust program that streamlined the PKGBUILD reviewing process a lot by, first of all, giving you a really neat list of patterns and behaviours that would make a PKGBUILD suspicios or even plain dangerous, then having a scriptable rule-based engine that would either abort that operation, or show warns and workarounds to you.

    I forgot its name, unfortunately, and I installed it on my previous installation (Garuda, now I'm on CachyOS).

    Very dumb of my part not to try to write that down before the OS change lol.

    [–] UncleReaton@lemmy.ml 3 points 22 hours ago (1 children)

    It was not that one, but yeah, it's basically the same.

    I just remembered the one(s) I used a while ago, tho, they were aur-guard, and aur-scanner, I used these two (the second one just because its aur-scan codes [OPTIONS] and aur-scan explain <CODE> commands.

    [–] sel@piefed.social 1 points 19 hours ago (1 children)

    I just don’t understand the process of I don’t have two minutes to read what I’m installing. It’s fucking batshit crazy that all these retards want to come use Linux which is fine but then when they get solid advice they tell us they can’t be bothered.

    [–] flying_sheep@lemmy.ml 3 points 19 hours ago

    Yeah, when something isn't in the official repos, NixOS exists, Flatpak exists, and they're all vetted.

    Wanting a super clean system where everything is managed by pacman is purely about taste, so if you want it, you clearly can be bothered to put in the 2 minutes of work.
