Looking into it, thanks for the headsup.
It is a know issue affecting multiple wordpress sites apparently. Either vulnerable plugin or something in wordpress: https://wordpress.org/support/topic/all-my-sites-6-hacked-with-soaksoakru?replies=5
Update: We have identified and removed the hacked files. The site should be okay now. May take a day for the warning to clear.
