You're worried about your fleet and that's great. I'm more concerned with the internet as a whole and Wordpress is just vuln after vuln.

I'm happy your systems are secure. That's great.

Unfortunately, that doesn't apply to the 1000s of installations done by amateurs, lax IT, etc. etc. that make the WP vulns a much bigger issue than the 300 you manage.

Manage on, friend.
