Prolexic Technologies - DDoS mitigation
1 This attack mitigation approach is said to be lower-cost than the
traditional approach of a company maintaining its own network firewall, making DDoS attack prevention an
option for most firms doing business on the web.

Industrial espionage - Distributed denial of service (DDoS) attack
1 The distributed denial of service (DDoS) attack uses compromised computer systems to
orchestrate a flood of requests on the target system, causing it to shut down and deny
service to other users. It could potentially be used for economic or industrial espionage with
the purpose of sabotage. This method was allegedly utilized by Russian secret services,
over a period of two weeks on a Cyberwarfare|cyberattack on Estonia in May 2007, in response
to the removal of a Soviet era war memorial.

CipSoft - 2013 DDoS Attacks
1 During August 2013, the company's main product suffered from a long period of DDoS
attacks, which led CipSoft to hire Prolexic for increased protection against DDoS
attacks. To compensate the players for the attacks, which made the game unplayable
for a long time, CipSoft distributed vouchers for premium time or double experience to
the players affected.http://www.tibia.com/news/?

DDoS
1 In computing, a 'denial-of-service (DoS)' or 'distributed denial-of-service (DDoS) attack' is an attempt to make a machine or network
resource unavailable to its intended User (computing)|users. Although the means to carry out, motives for, and targets of a DoS
attack may vary, it generally consists of efforts to temporarily or indefinitely interrupt
or suspend Network service|services of a Host (network)|host connected to the
Internet.

DDoS
1 As clarification, DDoS (Distributed Denial of Service) attacks are sent by
two or more persons, or bots. (See botnet) DoS (Denial of Service)
attacks are sent by one person or system.

DDoS - Asymmetry of resource utilization in starvation attacks
1 ** controlling a large number of computers and directing them to
attack as a group. A DDoS attack is the primary example of this.

DDoS - Distributed attack
1 A 'D'istributed 'D'enial 'o'f 'S'ervice 'A'ttack ('DDoS') occurs when
multiple systems flood the bandwidth or resources of a targeted system, usually one or more web servers

DDoS - Distributed attack
1 Malware can carry DDoS attack mechanisms; one of the better-
known examples of this was MyDoom. Its DoS mechanism was
triggered on a specific date and time. This type of DDoS involved
hardcoding the target IP address prior to release of the malware and
no further interaction was necessary to launch the attack.

DDoS - Distributed attack
1 In some cases a machine may become part of a DDoS attack with
the owner's consent, for example, in Operation Payback, organized by the
group Anonymous (group)|Anonymous.

DDoS - Distributed attack
1 More sophisticated attackers use DDoS tools for the purposes of
extortioneven against their business rivals.

DDoS - Distributed attack
1 If an attacker mounts an attack from a single host it would be classified as
a DoS attack. In fact, any attack against availability would be classed as a Denial of Service attack. On the other hand, if an attacker uses many
systems to simultaneously launch attacks against a remote host, this
would be classified as a DDoS attack.

DDoS - Reflected / Spoofed attack
1 ICMP Echo Request attacks (Smurf Attack) can be considered one form of reflected attack, as the flooding host(s) send Echo Requests to the
broadcast addresses of mis-configured networks, thereby
enticing hosts to send Echo Reply packets to the victim. Some early DDoS programs implemented a distributed form of this attack.

DDoS - Switches
1 Wan-link failover will work as long as both links have DoS/DDoS prevention mechanism.

DDoS - Clean pipes
1 All traffic is passed through a cleaning center or a scrubbing center via various methods
such as proxies, tunnels or even direct circuits, which separates bad traffic (DDoS
and also other common internet attacks) and only sends good traffic beyond to the server. The provider needs central connectivity to the Internet to manage this kind of service unless they happen to be located within the
same facility as the cleaning center or scrubbing center.

The Spamhaus Project - CyberBunker dispute and DDoS attack
1 Spamhaus also hired Cloudflare, a DDoS mitigation company, to assist them by distributing their internet
services across Cloudflare's worldwide network, after which the
focus of the attack was redirected to the companies that provide
Cloudflare's network connections.

The Spamhaus Project - CyberBunker dispute and DDoS attack
1 According to The New York Times Kamphuis also claimed to be the
spokesman of the attackers, and said in a message We are aware that this is one of the largest DDoS attacks
the world had publicly seen, and that CyberBunker was retaliating against Spamhaus for abusing their influence

The Spamhaus Project - CyberBunker dispute and DDoS attack
1 The British National Cyber Crime Unit revealed that a London schoolboy
had been secretly arrested as part of a suspected organised crime gang responsible for the DDoS attacks

Direct Connect (file sharing) - Direct Connect used for DDoS attacks
1 As the protocol allows hubs to redirect users to other hubs,
malicious hubs have redirected users to places other than real Direct
Connect hubs, effectively causing a DDoS|Distributed Denial of Service attack. The hubs may alter the IP
Address|IP in client to client connections, pointing to a potential
victim. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html
Direct Connect (file sharing) - Direct Connect used for DDoS attacks
1 The CTM Exploit surfaced in 2006–2007, during which period the whole Direct Connect network suffered from
DDoS attacks. The situation prompted developers to take security
issues more seriously.

Gwyneddosaurus
1 They noted that this would make Gwyneddosaurus a synonym
(taxonomy)|senior synonym of Tanytrachelos, and recommended conserved name|conserving the younger but better-represented
genus.

which, while affecting some systems, allowed GreenNet to discover the site which was being
targeted.http://mailman.greennet.org.uk/pipermail/greennet-l/2013-August/000122.html In October 2013, the target was revealed to be the
