Awesome!
Since i installed this i finaly found my site secure, only modifications to the core were the ones i mage my self. it's not showing any iframes but there clearly is one, you can find my topic about it here: https://wordpress.org/support/topic/found-miner-in-majority-of-wordpress-sites/#post-10317242 im still investigating what this might be tho, since the main adress of that iframe is a monero miner page... Any sugestions about this iframe would be greatly appreciated!

Found loads of malicious modifications on my site
Of course this plugin is not THE magic cure for infected sites, but it helped me to find many infected scripts on my site and i was able to fight back the hackers in a more efficient way. Great tool, does exactly what it says in a convenient way, showing you a diff view of the detected changes if you want, even realizing when there are 'only whitespace changes'. This saved me a lot of work!

Promising!
I've modified the review after discussion with the author This is a very useful tool! The free API limit might be a little low if you want to test the site recurrently but it's still a useful tool.
