Getting lots of server errors directory index forbidden by Options directive from same referer
I'm running a Wordpress site as well. Recently started seeing the same thing from this referer. The error indicates that binance.com has a page that is attempting to include a directory as though it was a file. Something like this:
<link rel="stylesheet" href="https://website.com/wp-admin/css/">
My guess is that this is actually some kind of security scan unrelated to binance.com that is just using their hostname to distract from the scan itself, or spam/scam to drive traffic to binance.com. It appears there has been a rise in these occupancies in the last week or so. I see others reporting the same thing online. The good news is that your Apache config is such that directory listing is disabled. Directory listing is evil ;)
