In a quarrel between non-profit anti-spam group Spamhaus and Dutch web-host Cyberbunker has led to cyber-attacks of an unprecedented scale.

Among other services, Spamhaus maintains a block-list of servers known to be used for malicious purposes, such as spam, malware, or illegal content. Servers hosted by Cyberbunker were recently added to the list. Cyberbunker has made a name for itself by stating it will host anything except child porn and terrorism-related materials.

According to the BBC, Sven Olaf Kamphuis, who claims to be a spokesman for Cyberbunker, said in a message that Spamhaus was abusing its position, and should not be allowed to decide “what goes and does not go on the internet”. Spamhaus has accused Cyberbunker of the attacks, saying Cyberbunker is in cooperation with “criminal gangs” from Eastern Europe and Russia to launch an attack on its servers

The attacks have taken the form of the classic a DDoS (Distributed Denial of Service), which attempts to overload servers by sending through more requests for data than the system can handle, thereby locking it up and denying any service to others trying to access it. While a common form of online attack, the assault on Spamhaus is being conducted on an “unprecendented scale”. The attacks have targeted the Domain Name Service (DNS) servers of Spamhaus.

Speaking to the BBC on 27 March 2013, Steve Linford, chief executive for Spamhaus said “We’ve been under this cyber-attack for well over a week.” “These attacks are peaking at 300 gb/s (gigabits per second). Normally when there are attacks against major banks, we’re talking about 50 gb/s,” said Linford.

Reportedly cyber-police teams from five nations have joined the investigation into the attacks
