Probably reinstall (all is supposed to be fixed as of over 12h ago). This time check the PKGBUILD and also whichever (git) repo the software is pulled from.
See if infected versions of npm packages atomic-lockfile and js-digest are installed.
libgdata here is specifically very messy. It was an official package since it was a required dependency for older versions of GNOME, then in GNOME 50 they dropped the dependency and so did Arch from their repos. But because pacman doesn’t remove dangling dependencies, you end up with libgdata still installed, until Arch Linux moves dropped packages into the AUR as an orphan, which happened in this case 5/31. This allowed it to be perfectly timed for the attackers to pick it up on 6/11. Now, you’d inadvertently update libgdata from an AUR source if you’re using an AUR helper.
What to do if I found a package I installed to be in that list? libgdata to be specific?
Have a check if you updated it recently (PKGBUILD history, about June 10-12). If not you’re fine.

Personally I would reset everything if I got anything, to kill both any infection and my paranoia. Then reset credentials.

Was it installed from the aur? If not, you’re fine
