According to a report by The New York Times, the battle started when Spamhaus added CyberBunker to its blacklist for allegedly distributing a large amount of spam.
This in turn provoked Cyberbunker to launch the largest DDoS attack in the history of the Internet out of retaliation, which is thought to be “causing widespread congestion and jamming crucial infrastructure around the world.”
Cyberbunker’s business model is largely successful based on its acceptance of all kinds of customers, with the exception of those individuals and groups engaged in child pornography and terrorism-related activities.
The attack, which has been going on for over a week, differs from other DDoS attacks in that it is significantly larger.
Peaking at 300 gigabits per second, the attack is six times greater than comparable attacks designed to take down well-defended websites, such as banks.
The attack is targeting Spamhaus’ DNS servers, which is causing some services, such as Netflix, to slow down across the Internet as a result of the massive amount of data hitting the DNS through the attack.
CloudFlare CEO Matthew Prince told the Times that these kinds of DDoS attacks “are essentially like nuclear bombs,” and that it is “so easy to cause so much damage.”
Though Cyberbunker has not confirmed that it is responsible for the attacks, Spamhaus believes the hosting provider is to be blamed. The anti-spam group says that “criminal gangs” originating from Eastern Europe and Russia are also partially responsible for the attacks.
In the Times report, an Internet activist representing CyberBunker says the DDoS attacks are the result of Spamhaus using spam as a cover to shut down websites they do not agree with.
