Constant login attempts on port 443

[Amongthegums]

Hi

Among the security measures implemented on our site is "Admin Tools", which I have also used to geo block most eastern european countries, Ukraine, Georgia, Russia etc.. They were sources of mischief that have previous made my life a misery.

With the measures taken we got failed attempted login reports from Admin Tools down to a couple a day.

However, today I am seeing something different. Over the last 24 hours our backend is being hammered with (failed) attempted backend logins from IP addresses out of Georgia. Each attempt is being reported reaching https://ourdomain.org:443

Can someone enlighten me why these miscreants are using port 443 for the login?

And should I worry?

Thanks

It's probably automatic bots not "actual people" and it is because, I assume, your site is running with a SSL certificate, for which the HTTPS protocol uses Port 443 (if not for the whole site, then for the Administrator end). The normal protocol (HTTP) uses port 80).

What other security functions do you have in place e.g. 2-factor authentication, or other Admin Tools functions such as the administrator directory being password protected (htaccess) or the "secret key" function?
