From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

On the 16th of July, at around 8pm UTC+2, a malicious AUR package was uploaded to the AUR. Two other malicious packages were uploaded by the same user a few hours later. These packages were installing a script coming from the same GitHub repository that was identified as a Remote Access Trojan (RAT).

The affected malicious packages are:

  • librewolf-fix-bin
  • firefox-patch-bin
  • zen-browser-patched-bin

The Arch Linux team addressed the issue as soon as they became aware of the situation. As of today, 18th of July, at around 6pm UTC+2, the offending packages have been deleted from the AUR.

We strongly encourage users that may have installed one of these packages to remove them from their system and to take the necessary measures in order to ensure they were not compromised.

Follow up

There are more packages with this malware found.

  • minecraft-cracked
  • ttf-ms-fonts-all
  • vesktop-bin-patched
  • ttf-all-ms-fonts

What to do

If you installed any of these packages, check your running processes for one named systemd-initd (this is the RAT).

The suspicious packages have a patch from this now-inaccessible Codeberg repo: https://codeberg.org/arch_lover3/browser-patch

The Arch maintainers have been informed of all this already and are investigating.

minecraft-cracked

Gotta assume that if any Arch users actually fell for that one, that they either let their kids use their device or they're generally not smart ( which absolutely goes against my stereotypical view of an arch user ).

[–] pfr@lemmy.sdf.org 1 points 36 minutes ago

The stereotype of arch uses generally being smart is no longer. The "I use arch btw" meme brought a whole new user base to arch. You'll find them on r/unixporn showing off their hyperland rice that they copied from some other user..

We are getting to the point where inviting more people in means we will need an automated babysitter to watch for this shit and to pull it once it’s discovered. Apple has a walled garden approach that’s certainly taken a big chunk of malware threats out of their devices but their walled garden approach is ridiculous and impractical for Linux. The Microsoft method of monitoring and second guessing everything with antimalware programs is also suspect because it is super easy to abuse and resource intensive. We have clamAV but clam kinda sucks.

Linux is at the point where we need something that audits what’s going in and automatically yanks it back out remotely if it’s found to be a problem. Things can only be added by the user, but the bot can remove them without interaction of the user.

I don’t see this happening though. Instead, I see this as more of a rust vs C thing all over again, where valid critiques are drowned out by “improve your skills bro.”

The affected malicious packages are:

  • librewolf-fix-bin
  • firefox-patch-bin
  • zen-browser-patched-bin

What a nice attack on privacy-friendly infrastructure.

And then, Arch AUR has such suspicious things like the Brave browser which claims to reduce tracking.... and works together with advertisers.

To be clear, AUR is fantastic if you develop some experimental package and you want to give it to your friends to try it out easily. But not as a general distribution mechanism.

[–] Jolteon@lemmy.zip 17 points 6 hours ago* (last edited 6 hours ago) (1 children)

To be fair the AUR is known to be very susceptible to that kind of thing due to the effective absence of entry requirements.

[–] MentalEdge@sopuli.xyz 9 points 3 hours ago (1 children)

Absolutely.

The Arch User Repository is a way for anyone to easily distribite software.

Hence it has never been secure, and rather than claim it is, you mostly see people and documentation warn you about this, and to be careful if using it.

Any schmuck can make whatever they want available via the AUR. That's how even the tiniest niche project can often be installed via the AUR. But you trade in some security for that convenience.

[–] derpgon@programming.dev 10 points 3 hours ago (1 children)

It shouldn't be used as a marketplace, it should be used as a repository. You can probably find a lot of malware on GitHub, doesn't mean you go there to choose your text editor.

I never search the AUR directly, I only use it if some README tells me I can install their software via an AUR package.

[–] Dima@feddit.uk 1 points 19 minutes ago

Yeah, I search the AUR not to discover packages, but to see if something I want to install is in there, if it is I check the PKGBUILD and make sure none of the sources/commands/patches are suspicious.
People need to remember it's not some carefully vetted app store and that they need to be the ones vetting any packages they install and any changes when updating.

[–] HaraldvonBlauzahn@feddit.org 6 points 5 hours ago (1 children)

Wait what happens once some government or state actor hacks rust's install script rustup with its curl | bash install procedure and relying on TLS certificates which are e.g. issued by the Russian government. (No, the rust project won't use a Russian/Chinese/US Gov certificate but your browser will trust near all of them...)

[–] Ephera@lemmy.ml 1 points 3 hours ago (2 children)

You're using that to download a program. If they can MitM the shell script, they can just as well MitM the program that you'll run right after the download...

[–] HaraldvonBlauzahn@feddit.org 4 points 3 hours ago (1 children)

That is why Debian uses digital pgp signatures for all packages. And the GNU project uses strong cryptographic hashes for install packages.

[–] wewbull@feddit.uk 2 points 2 hours ago

As does Arch.

[–] JackbyDev@programming.dev 2 points 3 hours ago

This is why we invented hash checking. Good thing they can't MITM where that's stored! /s

[–] oo1 0 points 2 hours ago

I already assumed aur was riddled with stuff like that.

Use a condom when fucking around in there.

[–] hobbsc@lemmy.sdf.org 25 points 11 hours ago (1 children)
[–] lagoon8622@sh.itjust.works 6 points 4 hours ago (1 children)

This is technically not Arch's fault btw. I use Arch but don't use AUR for this reason

[–] daggermoon@lemmy.world 8 points 4 hours ago (1 children)

Also same problem adding random PPA's on Debian and Ubuntu.

[–] lagoon8622@sh.itjust.works 11 points 3 hours ago

Agreed. Or piping random curl things into sh. Or downloading random exes on Windows etc

[–] Tundra@sh.itjust.works 102 points 14 hours ago (7 children)

this is going to increase in frequency as linux gains popularity

[–] nsrxn@scribe.disroot.org 1 points 2 hours ago

I use Debian btw

[–] DirkMcCallahan@lemmy.world 24 points 14 hours ago (7 children)

This is why I felt uncomfortable when I first switched to Linux and kept reading that I didn't need to worry about viruses as long as I didn't click on dodgy links and only installed from trusted sources. I'm sure I'm betraying my lack of security knowledge here, but that always seemed a bit too easy.

[–] mark@social.cool110.xyz 90 points 14 hours ago (8 children)

@DirkMcCallahan @Tundra The AUR isn't a trusted source, but most of the the Arch cult forget to mention that.

[–] caseyweederman@lemmy.ca 12 points 7 hours ago (1 children)

Half the posts on the Internet are people replying to requests for help with the message "read the wiki, the aur isn't a trusted source, dummy"

[–] muusemuuse@sh.itjust.works -1 points 4 hours ago (1 children)

Why do we have the AUR anyway?

[–] helix@feddit.org 11 points 4 hours ago (1 children)

Because it's convenient and a good way to start to write PKGBUILDs quickly without becoming a proper package maintainer.

[–] muusemuuse@sh.itjust.works 1 points 4 hours ago

Isn’t that like how alpinelinux’s community repository works too?

[–] copygirl@lemmy.blahaj.zone 83 points 13 hours ago* (last edited 13 hours ago) (2 children)

most of the the Arch cult forget to mention that

The "Arch cult's" holy book, the ArchWiki, states the following pretty clearly:

Warning: AUR packages are user-produced content. These PKGBUILDs are completely unofficial and have not been thoroughly vetted. Any use of the provided files is at your own risk.

Mention of one's use of the AUR for their needs doesn't need to come with a disclaimer.
People who don't read or don't use their brain are going to keep not doing so, regardless.

Arch is not responsible for idiots.

The AUR, key words “user repository” is a specific weak point. It doesn’t have the same level of oversight that the main arch repo has. Stick to main repos and verified flatpaks and it’s very unlikely that you’d ever be compromised.

Linux isn’t perfect, but it’s certainly better than windows where you just download executables willy nilly to install your software.

[–] HaraldvonBlauzahn@feddit.org 1 points 6 hours ago

BTW python's package index has roughly the same problem - but a far less technical, experienced and critical user base. NPM has this problem since years.

Expect these problems to rise with every percent more of new Linux users which never learned the difference between opening / viewing untrusted data, and running untrusted code, because Windows basically ignores this essential concept and Android tries to solve that with sandboxing each app.
