Is this plugin hacked? Calls to dead external files

Are you still maintaining this plugin? Does this plugin have malware?

10 months ago WebENFA asked why this plugin was linking to external files… i.e.
links to…
https://juliencayzac.me/files/custom.css and
https://juliencayzac.me/files/script.js

He didn’t mention it but there is also a Prefetch to https://juliencayzac.me

However, the IP address for juliencayzac.me is blacklisted and there is no site there any more. There are also many questionable and dangerous sites on that same IP address.

Please let us know what’s going on!
