Hi Quentin, Can you send us the packages description so we can identify other attempts in the future? Thanks Shay Date: Fri, 18 Jul 2025 18:53:19 +0200

From: Quentin MICHAUD <mh4ckt3mh4ckt1c4s@archlinux.org> Subject: [SECURITY] firefox-patch-bin, librewolf-fix-bin and zen-browser-patched-bin AUR packages contain malware To: aur-general@lists.archlinux.org Message-ID: <4156647e-59ab-4026-9778-19d7cda6d4bc@archlinux.org> Content-Type: text/plain; charset=UTF-8; format=flowed

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.
