The compromise was reported and other AUR maintainers have been working to remove the infected packages.

Presumably, it's related to the numerous sustained DDOS attacks on aur
@ifin AUR is not guarded by proper signatures?
@waldi anyone can sign up for an account and adopt orphaned packages, then push updated PKGBUILDs
@ifin Nothing sophisticated, really.
@rgacogne
The use of an eBPF rootkit is beyond most supply chain attacks we see.
@ifin „sophisticated“ as in „Trust me bro I will maintain your package“
