So you read newspapers? You know DDoS happened last year? What about right now at this instance?
Watch in Awe the multi Gigabit DDoS attacks happening worldwide right now!!! .. Truly amazing and scary. See DDOS attacks maps live on this world #LiveDDoS attack maps. Very interesting interactions between USA and China.
In time I will add more monitoring (there are quite a few more but they are not Live). Before we go in and see the maps lets go over the basics first.
Note: These maps are severely CPU and memory(RAM) intensive.
If you’re behind a proxy server, NORSE maps wont work.
I’ve edited the maps to allow you to view on any screen size. (i.e. mobile or large LCD)

What is DDoS?
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 users.
Although the means to carry out, the motives for, and targets of a DoS attack vary, it generally consists of efforts to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet.
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. As of 2014, the frequency of recognized DDoS attacks had reached an average rate of 28 per hour.
Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root nameservers.
DoS threats are also common in business, and are sometimes responsible for website attacks.
This technique has now seen extensive use in certain games, used by server owners, or disgruntled competitors on games, such as server owners’ popular Minecraft servers. Increasingly, DoS attacks have also been used as a form of resistance. Richard Stallman has stated that DoS is a form of ‘Internet Street Protests’. The term is generally used relating to computer networks, but is not limited to this field; for example, it is also used in reference to CPU resource management.
One common method of attack involves saturating the target machine with external communications requests, so much so that it cannot respond to legitimate traffic, or responds so slowly as to be rendered essentially unavailable. Such attacks usually lead to a server overload. In general terms, DoS attacks are implemented by either forcing the targeted computer(s) to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.
Denial-of-service attacks are considered violations of the Internet Architecture Board’s Internet proper use policy, and also violate the acceptable use policies of virtually all Internet service providers. They also commonly constitute violations of the laws of individual nations.
Some interesting facts
- According to TrendMicro Research $150 can buy a week-long DDoS attack on the black market.
- According to ATLAS Threat Report more than 2000 daily DDoS Attacks are observed world-wide by Arbor Networks.
- According to Verisign/Merril Research worldwide 1/3 of all downtime incidents for different online services are attributed to DDoS attacks.
- Attackers build networks of infected computers, known as ‘botnets’, by spreading malicious software through emails, websites and social media. Once infected, these machines can be controlled remotely, without their owners’ knowledge, and used like an army to launch an attack against any target. Some botnets are millions of machines strong.
- Botnets can generate huge floods of traffic to overwhelm a target. These floods can be generated in multiple ways, such as sending more connection requests than a server can handle, or having computers send the victim huge amounts of random data to use up the target’s bandwidth. Some attacks are so big they can max out a country’s international cable capacity.
- Specialized online marketplaces exist to buy and sell botnets or individual DDoS attacks. Using these underground markets, anyone can pay a nominal fee to silence websites they disagree with or disrupt an organization’s online operations. A week-long DDoS attack, capable of taking a small organization offline can cost as little as $150.
Types of Attacks
Attack Class: Four common categories of attacks
TCP Connection Attacks – Occupying connections
These attempt to use up all the available connections to infrastructure devices such as load-balancers, firewalls and application servers. Even devices capable of maintaining state on millions of connections can be taken down by these attacks. Learn more…
Volumetric Attacks – Using up bandwidth
These attempt to consume the bandwidth either within the target network/service, or between the target network/service and the rest of the Internet. These attacks are simply about causing congestion. Learn more…
Fragmentation Attacks – Pieces of packets
These send a flood of TCP or UDP fragments to a victim, overwhelming the victim’s ability to re-assemble the streams and severely reducing performance. Learn more…
Application Attacks – Targeting applications
These attempt to overwhelm a specific aspect of an application or service and can be effective even with very few attacking machines generating a low traffic rate (making them difficult to detect and mitigate). Learn more…
Amplification: Two ways attacks can multiply traffic they can send
DNS Reflection – Small request, big reply
By forging a victim’s IP address, an attacker can send small requests to a DNS server and ask it to send the victim a large reply. This allows the attacker to have every request from its botnet amplified as much as 70x in size, making it much easier to overwhelm the target. Learn more…
Chargen Reflection – Steady streams of text
Most computers and internet connected printers support an outdated testing service called Chargen, which allows someone to ask a device to reply with a stream of random characters. Chargen can be used as a means for amplifying attacks similar to DNS attacks above Learn more…
Here’s a list of all possible UDP Based attacks I’ve compiled in my previous post
- Quake Network Protocol
- Steam Protocol
The list of known protocols, and their associated bandwidth amplification factors, is listed below. US-CERT would like to offer thanks to Christian Rossow for providing this information to us.
|Protocol||Bandwidth Amplification Factor||Vulnerable Command|
|DNS||28 to 54||see: TA13-088A |
|NTP||556.9||see: TA14-013A |
|CharGEN||358.8||Character generation request|
|Kad||16.3||Peer list exchange|
|Quake Network Protocol||63.9||Server info exchange|
|Steam Protocol||5.5||Server info exchange|
NORSE Attack Map by Norse Corp
Norse Dark Intelligence
Every second, Norse collects and analyzes live threat intelligence from darknets in hundreds of locations in over 40 countries. The attacks shown are based on a small subset of live flows against the Norse honeypot infrastructure, representing actual worldwide cyber attacks by bad actors. At a glance, one can see which countries are aggressors or targets at the moment, using which type of attacks (services-ports).
Hovering over the Attack Origins, Attack Targets, or Attack Types will highlight just the attacks emanating from that country or over that service-port respectively. Hovering over any bubble on the map, will highlight only the attacks from that location and type. Press s to toggle table sizes. You can also minimize the bubbles.
Norse exposes its threat intelligence via high-performance, machine-readable APIs in a variety of forms. Norse also provides products and solutions that assist organizations in protecting and mitigating cyber attacks.

To protect your website, you need to be able to block or absorb malicious traffic. Webmasters can talk to their hosting provider about DDoS attack protection. They can also route incoming traffic through a reputable third-party service that provides distributed caching to help filter out malicious traffic — reducing the strain on existing web servers. Most such services require a paid subscription, but often cost less than scaling up your own server capacity to deal with a DDoS attack.
Google Ideas has launched a new initiative, Project Shield, to use Google’s infrastructure to support free expression online by helping independent sites mitigate DDoS attack traffic.
Through the continued collaboration of the many stakeholders involved in improving the Internet, a number of efforts can help to reduce the threat of DDoS attacks.
For example, ten years ago the Network Working Group of the Internet Engineering Task Force published BCP 38 (also known as RFC 2827) as a best practice guideline for how ISPs and hosting providers can filter fake IP addresses to reduce the impact of DDoS activity on themselves and others. Unfortunately, many ISPs have still yet to implement these best practices, preventing its benefits from being fully realized by the wider internet community.
Distributed Denial of Service (DDoS) attacks can be used to make important online information unavailable to the world. Sites covering elections are brought down to influence their outcome, media sites are attacked to censor stories, and businesses are taken offline by competitors looking for a leg up. Protecting access to information is important for the Internet and important for free expression.
