I received a "support" email from Yahoo Support that was actually spam or more likely phishing. It passed spf/dkim/dmac checks because it was from an Yahoo account (that has probably been disabled by now, if others reported similar emails. The link to "revalidate" my account had a Yahoo title but went to a Google site.

I don't see it now when I reopen the email, but I think that the original email had an AI summary of the email that basically just reiterated the message. The AI summary directed me to follow the directions rather than warned me away from doing so.

If there's anything an AI ought to catch, it's email that says it's from Yahoo support that comes from a non-corporate account with a link to an offsite non-corporate-yahoo web address.
