Everyday for the last 6 weeks this site is being attacked about 15+ times a day from IP addresses all around the world. I get notices of a CSRF Shield attempt all day long. The attacked URL is a RSJoomla Contact form and the software is up-to-date.
My questions are:
What is the best way to stop this continuation of attack? Ban all attacking IP's?
Has the attack gone through or has Admintools blocked the attack?
I have looked up the IP addresses and most are known attacker IP's and are presently on Blacklists.
I know having too many IP's banned can adversely effect the performance of the site. Again, what is the best action to mitigate this problem. I have been using Admintools for many years now and this is the first time anything on this scale has occurred.
Thanks for your help.
