AUR compromise

The Arch Linux AUR (Arch User Repository) had over 400 packages compromised with malware

There's a thread on the public AUR Mailing List with people reporting packages, where it seems like over 400 packages were hit with the issue. Arch packager Jonathan Grotelüschen mentioned work was ongoing to "reset/delete all malicious commits and ban the accounts".

I'm trying to understand the details of AUR processes for submitting PKGBUILDs. In other words, how exactly did this happen? arojas submitted hundreds of changes to PKGBUILD or related files. And they were just...accepted? What am I missing?

We will not edit your comments. However, we may delete your comments, or cause them to be hidden behind another link, if we feel they detract from the conversation. Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
