Cybersecurity company Comodo has become one of the major victims of a recently disclosed vBulletin 0-day vulnerability , exposing login account information of over nearly 245,000 users registered with the Comodo Forums websites. In a brief security notice published earlier today, Comodo admitted the data breach, revealing that an unknown attacker exploited the vBulletin vulnerability (CVE-2019-16759) and potentially gained access to Comodo Forums database. It's worth noting that Comodo forum was hacked on September 29, almost four days after vBulletin developers released a patch to let administrators address the vulnerability, but the company failed to apply the patches on time. As The Hacker News broke the news last week, an anonymous hacker publicly disclosed details of a critical then-unpatched vulnerability in vBulleti

December 04, 2013Mohit Kumar
In a recent cyber attack on a Forum site, thousands of outdated legitimate WordPress blogs were abused to perform DDOS attacks using previously known vulnerabilities . After analyzing the Log file from the victim's server, we have noticed many Wordpress CMS based educational (.EDU) and Government (.GOV) websites from where the attack was originated. 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 mi
