The Importance Of Spamhaus Attacks Cannot Be Questioned

Posted on: May 29th, 2013

The Importance Of Spamhaus Attacks Cannot Be QuestionedThere has been a major clamour on the fact that the attacks on Spamhaus should divert attention from real security threats which have been highlighted from these service attacks. The fact that these Spamhaus attacks involved 300Gbps of traffic alone makes them noteworthy irrespective of the fact that they choked up various portions of the Internet or not. Several security firms confirm seeing traffic of about 300gbps which they claim is three times greater than the largest DDoS attack which has taken place up to date. The chart posted on the blog of Abor Networks, a company which helps to prevent DDoS attacks clearly shows the humongous difference between the Spamhaus attacks and the other known large attacks.

Matthew Prince has also claimed that the Spamhaus attacks caused certain portions of the Internet to slow down because of their huge size. However, this assertion has been openly criticized by many. Renesys, a firm engaged in network performance tracking states that the Spamhaus attacks did not lead to any disruptions of the Internet as a whole. The firm also states that while these attacks were large enough to affect the standard web hosting centres, they were not large enough to affect the core components of the Internet. Keynote Systems, another firm engaged in network performance tracking, also sides with Renesys in its analysis of the Smaphaus attacks. The company noted that these attacks did not have major effects on the Internet since the website speeds all over Europe remained normal.

As a result of these statements, most began to wonder if CloudFlare had played up the attacks to get some cheap publicity for itself. While it may be a legitimate question, it is definitely not an important one in the present situation. Even if they did hype the situation, the fact that the Spamhaus attacks were larger than any other DDoS attack witnessed in the past cannot change. Moreover, the hackers took advantage of the open DNS servers to help them generate the huge volumes of traffic which were required for such attacks.

This fact becomes extremely important as most industry experts had been ranting on about the threat posted by the open DNS servers for quite some time. The biggest problem with open DNS servers is that they are extremely insecure since they also accept and respond to queries which lie outside their domains. According to estimates, there are more than 27 Million servers which have open resolvers and about 25 million of these servers pose a major threat in terms of security. Moreover, only a fraction of such servers was used in the attacks on Spamhaus. One could only imagine what would be the state if more open DNS servers began to be used in such attacks.

Thus, the Spamhaus attacks hold great importance as they have helped in diverting attention to this long overdue issue. Industry experts are now hoping that thanks to these attacks, the DNS and ISP server operators will be looking into making their servers much more secure to prevent similar attacks in the future.
