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.

Thousands of WordPress Blogs Compromised for DDoS Attacks

September 25, 2013

A massive cyber attack campaign is currently targeting numerous WordPress websites across the internet. In April 2012, we reported on a widespread brute force attack against millions of WordPress sites, resulting in the compromise of approximately 90,000 servers to form a large botnet of WordPress hosts. Recent DDoS attack logs received from reader Steven Veldkamp at ‘The Hacker News’ reveal that victims’ websites are experiencing heavy DDoS attacks, stemming from various compromised WordPress sites.

Utilizing brute force techniques on WordPress administrative portals, hackers are exploiting poorly secured hosts using commonly known username and password combinations. An analysis of DDoS attack logs from September 23, 2013, indicates a storm of malicious activity over just 26 seconds…

16-Year-Old Arrested for Involvement in History’s Largest Cyber Attack

Sept 27, 2013

A 16-year-old has been detained for allegedly participating in the largest DDoS attack ever recorded, targeting the Dutch anti-spam organization Spamhaus. The arrest, made by British police in April, came to light recently. Authorities stormed his home in south-west London after discovering substantial funds in his bank account. Upon investigation, he was found with various computer systems logged into virtual forums. The March 20 attack on Spamhaus was described as a monumental event in cybercrime, unleashing a torrent of traffic measured at 300 billion bits per second (300Gbps). DDoS attacks occur when hackers mobilize a network of infected computers to overwhelm a server, leading to shutdowns.

13 Members of Anonymous Charged in ‘Operation Payback’ Cyber Attack Scheme

Oct 04, 2013

A U.S. Grand Jury has indicted 13 alleged members of the hacking collective Anonymous for their involvement in cyber attacks against various websites during the anti-copyright initiative known as “Operation Payback.” The group executed denial-of-service (DDoS) attacks on sites belonging to organizations like the Recording Industry Association of America, Visa, and MasterCard. These actions were in retaliation for the closure of “The Pirate Bay,” a Swedish file-sharing platform used for illegal downloads. The DDoS campaign later targeted Bank of America and other credit card companies after they declined to process payments for WikiLeaks. The indictment charges the suspects with conspiracy to intentionally damage protected computers and using software called Low Orbit Ion Cannon (LOIC) to facilitate the attacks.

South Korea Faces Android Trojan Threats, Malware in Gaming Apps, and DDoS Assaults

Oct 25, 2013

Last Tuesday, the National Police Agency of South Korea issued a warning about the proliferation of malware-infected video games available in the South Korean market, designed to facilitate cyberattacks against the country. This malware collects users’ location data and IP addresses, reportedly transmitting the information to servers based in North Korea.

Today, AhnLab, South Korea’s leading antivirus company, confirmed that they have detected distributed denial-of-service (DDoS) attacks targeting the websites of local businesses. The report indicates that approximately 16 websites belonging to 13 companies, including Daum, MSN, and the JoongAng Ilbo newspaper, have been affected. AhnLab noted that around 10,000 computers were compromised, primarily due to the failure to install or update antivirus programs since the last cyberattack in July. The attack was first identified around 4:00 p.m. on Thursday, impacting roughly 10,000 systems.
