Over the past month my blogs appears to be under constant assault from some persistent hackers trying get past the wp-login. I have taken the usual precautions such as a security plugin, backups and I have access to the files directly. I can track the IPs and have been blocking some of those but some of these sites are so toxic I have to use my Linux box to check them. So far they have been unsuccessful but I don't get it. My sites are not ecommerce and are basically brochure sites so what's the goal? Even if they take control I'll simply delete the files and reinstall. I don't get in, anybody have any suggestions?
