Suspected Hacker Arrested in Connection with Historic DDoS Attack on Spamhaus

April 27, 2013

Dutch police have arrested a 35-year-old man linked to a colossal DDoS attack on the anti-spam organization Spamhaus that occurred in March. This attack, which peaked at over 300 Gbps, is recorded as the largest DDoS attack ever. Spamhaus, known for creating blacklists that identify spam sites for Internet Service Providers, experienced a severe disruption as its website was overwhelmed with traffic.

Following the attack, Spamhaus enlisted CloudFlare for protection against future threats. The arrest took place in Barcelona under a European arrest warrant, with plans for the suspect’s transfer to the Netherlands. The individual arrested is believed to be Sven Kamphuis, the owner of Dutch hosting company Cyberbunker, which has been connected to the attack. This incident is thought to have been triggered by Spamhaus blacklisting Cyberbunker.

Cloudflare Successfully Thwarts Unprecedented 11.5 Tbps DDoS Attack

Cloudflare announced on Tuesday that it effectively mitigated a record-breaking volumetric distributed denial-of-service (DDoS) attack that peaked at 11.5 terabits per second (Tbps). In a recent post on X, the web infrastructure and security provider revealed, “In recent weeks, we’ve autonomously blocked numerous hyper-volumetric DDoS attacks, with the largest reaching peaks of 5.1 Bbps and 11.5 Tbps.” The attack, primarily a UDP flood originating from Google Cloud, lasted only about 35 seconds, highlighting the company’s robust defense mechanisms at work. Volumetric DDoS attacks aim to overwhelm a target with excessive traffic, causing server slowdowns or failures, often resulting in network congestion, packet loss, and service disruptions. Typically, these attacks are executed using botnets controlled by threat actors.
