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.

[PSA] Malware distributed on the AUR (lists.archlinux.org)

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.

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

As does Arch.

Sure, I guess, if you've got a distro installed on your PC and use the distro-provided packages to install the Rust compiler, then you can't be subject to such certificate MitM attacks.

Your comment sounded like you were primarily concerned about the shell script piping rather it just being a program which can be downloaded without going through distro packages.

The AUR install scripts are just downloaded shell scripts which are executed (hopefully after inspection).

curl | bash just skips the inspection step - curl downloads to stdout, bash executes from stdin.
