WordFence Alerts - Increased Attack Rates

I woke up this morning to 47 emails from Wordfence saying that they have detected and blocked multiple attacks in the last 10 minutes. The emails spanned over a period of about 3 hours.

Here is some text from one of the emails:

The Wordfence Web Application Firewall has blocked 185 attacks over the last 10 minutes. Below is a sample of these recent attacks:

I have the free version of Wordfence. Is there anything I need to do? Or is this just Wordfence doing its job?

I have the same problems. A lot of login attempts over periods of days

So following this thread

I had it a few weeks back, just the once, then no more. Good to know WF is doing it's job well

Considering the speed it happens it looks to be an automated attack that is looking for a misconfigured server.

This probably happens more than you'd think, but if things are up to date and set up correctly you should be fine. Servers are constantly being scanned like this in a variety of ways, as I'm sure there are lots of misconfigured setups out there that are easily exploited. Happens a lot to your SSH and other ports too.
