Over the past few days we have begun noticing several specific attack profiles against Wordpress installations. This has been happening Internet wide from talking to other hosts and from general posts in public forums showing the same traffic.
Due to the distributed nature of this attack, it is causing significant performance problems on some of our servers as dozens of Wordpress sites are being attacked on the same server, at the same time.
We are using several different methods to block this traffic, both hardware firewalls and many different software tweaks to our web server configuration. A combination of these modifications have been successful in mitigating the attacks.
