Alert from Hacker News: Some Outdated WordPress Blogs Used in DDOS Attacks

In the past we have reported about many such cyber attacks, where attackers hacked into the WordPress blogs using password brute-force attack or they used the PINGBACK vulnerability in older versions of WordPress without compromising the server.

WordPress has a built in functionality called Pingback, which allows anyone to initiate a request from WordPress to an arbitrary site and it can be used for a single machine to originate millions of requests from multiple locations.

We have seen more than 100,000 IP addresses involved in the recent DDOS attack and the victim’s Forum website received more than 40,000 requests in 7 minutes from different WordPress blogs and IP addresses.
