[SECURITY BREACH?] What is Proudflex.org?

I’ve noticed (today especially) that embed blocks are not refreshing and the status line indicates …

Waiting for proudflex.org

A direct request to this domain shows this:


Every refresh of an embed block regardless of the domain it is calling will show this waiting… status line and eventually it resolves which suggests proudflexorg is analyzing the content in some way.

There are hints in search that this is related to malware and I must ask - why would a secure context in Airtable calling out to a block be exposed to malware?

I’ve performed all the usual and customary scans of my Mac and router, etc looking for any signs of invasive malware - nothing here. But, I’m not a security expert at all, so any clues would be helpful.
