Hi,
So apparently the plugin Related Posts by iLen has been leaked. We found this problem on our website and also some websites we build for clients.
The title in the Plug-in WordPress webpage search is “yuzo-related-post” By Lenin Zapata and in the back-end from WP “Related Posts” By iLen.
https://wordpress.org/support/topic/remove-this-plugin-immediately/ Says to delete this plugin IMMEDIATELY.
SO GO AHEAD AND DELETE IT. Why are you still reading this post? Do you want a joke or something? Your website is being hacked..
WP Version: 5.1.1.
THEME Version: latest
Plugin Related Posts Version: 5.12.84
