I'm confused though, it says the site injected malware into its archived form. But the HN title says archive.today injected the malware.
The archive.today site is the one injecting the malware, not the site being archived.
You said the same thing twice. “The site” == archive.today
The claim is that archive.today is injecting malware into archived pages. Given some of the past behavior, this is not hard to believe.
