In a Pastebin post dated October 8, the hacktivist group announced plans for several attacks: on Capital One on October 9, SunTrust on October 10, and Regions Financial Corp on October 11—and they successfully executed their threats. A spokesperson for SunTrust, Michael McCoy, confirmed that the bank’s site experienced heightened traffic, leading to intermittent availability for some online functions.

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.

LulzSec Hackers Facing Sentencing for Cyber Attacks on CIA and Pentagon

Four individuals linked to the hacking group LulzSec appeared in a London court for sentencing on Wednesday. Ryan Ackroyd, Jake Davis, Mustafa al-Bassam, and Ryan Cleary have all pleaded guilty to various hacking offenses. The name LulzSec combines “lulz,” meaning to laugh out loud, and “security,” signaling a mockery of online security measures. Emerging from their bedrooms in 2011, they orchestrated attacks that inflicted millions of pounds in damages on entities like the NHS, CIA, and U.S. military websites, resulting in the theft of sensitive data, including emails, passwords, and credit card details of hundreds of thousands of individuals. Southwark Crown Court heard that they also executed distributed denial of service (DDoS) attacks that crashed numerous websites. Ackroyd, 26, from Mexborough, South Yorkshire, admitted to stealing data from Sony.

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.
