This plugin was used to add malware to my website.

It added in a string eval of lots of numbers which equated to a redirect to a spam site.

It loaded this script:
developerstatss.ga
Which redirected to this site:
https://declarebusinessgroup.ga
Which then redirected to this site:
https://sinistermousemove.art

Uninstalling this plugin fixed the issue.
