The attack is possibly the largest in history, slowed down the Internet locally

A recent DDoS attack on the infamous – in some circles – Spamhaus, which some hyperbolically labeled as a DDoS attack that took down the "Internet," remains one of the biggest ever launched.

Its sheer size got authorities more interested than usual in finding out who was behind it.

Dutch authorities have announced that they have arrested the chief suspect in the case, who has only been referred to as SK. The 35-year-old was apprehended in Spain and is being transferred to authorities in the Netherlands.

Spamhaus and several organizations tied to it were targeted by a massive DDoS attack last month. It all started after the controversial anti-spam organization added Cyberbunker, a Dutch hosting company which is known to be very liberal with the sites it hosts.

Spamhaus accused Cyberbunker of being a spam heaven and proceeded to add all sites hosted by Cyberbunker to its spam list.

This led to a retaliation from those relying on Cyberbunker, though the hosting company later denied having anything to do with the attack.

Apart from Spamhaus sites, other points were attacked, including the London Internet Exchange, a major regional hub. The attack created some local slowdowns, though Spamhaus itself mostly stayed online.

Rumors say that the man in question is Sven Kamphuis, the owner of Cyberbunker, despite denials of any implication.
