take down the targeted website or slow it down by flooding the network, server or application with fake traffic. When against a vulnerable resource-intensive endpoint, even a tiny amount of traffic is enough for the attack to succeed." } }, { "@type": "Question", "name": "What is the objective of a DDoS attack?", "acceptedAnswer": { "@type": "Answer", "text": "The objective of a DDoS attack is to prevent legitimate users from accessing your website. Unlike other types of attacks, attackers do not use DDoS to breach your security perimeter. Instead, DDoS attacks are used to take down your website and prevent legitimate traffic, or used as a smokescreen for other malicious activities." } }, { "@type": "Question", "name": "What makes a DDoS attack successful?", "acceptedAnswer": { "@type": "Answer", "text": "For a DDoS attack to be successful, the attacker needs to send more requests than the victim's server can handle. Another way successful attacks occur is when the attacker sends bogus requests." } }, { "@type": "Question", "name": "How does DDoS work?", "acceptedAnswer": { "@type": "Answer", "text": "A DDoS attack will test the limits of a web server, network, and application resources by sending spikes of fake traffic. Some attacks are just short bursts of malicious requests on vulnerable endpoints such as search functions. DDoS attacks use an army of zombie devices called a botnet. These botnets generally consist of compromised IoT devices, websites, and computers." } }, { "@type": "Question", "name": "What is the difference between DoS & DDoS?", "acceptedAnswer": { "@type": "Answer", "text": "Denial of Service (DoS) attacks and Distributed Denial of Service (DDoS) attacks are very similar. The only difference between them is their scale. Single DoS attacks come from one source, while DDoS (distributed) attacks come from multiple locations, often spoofed." } }, { "@type": "Question", "name": "Can DDoS attacks steal information?", "acceptedAnswer": { "@type": "Answer", "text": "DDDoS attacks cannot steal website visitors information. The sole purpose of a DDoS attack is to overload the website resources. However, DDoS attacks can be used as a way of extortion and blackmailing. For example, website owners can be asked to pay a ransom for attackers to stop a DDoS attack." } }, { "@type": "Question", "name": "What happens during a DDoS attack?", "acceptedAnswer": { "@type": "Answer", "text":"A DDoS attack depletes the server resources and increases the website load time. When a DDoS attack hits a website, it may suffer performance issues or crash the server completely by overwhelming the server’ resources such as CPU, memory or even the entire network. Most DDoS attacks today originate from a hacker-controlled botnet of vulnerable IoT devices. This includes internet connected security cameras, household appliances, smart TVs, home lighting systems, and even refrigerators." } }] } </script> <meta name="generator" content="performance-lab

Anyone with a financial or ideological motive can damage an organization by launching a DDoS attack against it.</p> </div> </div> </div> </div> </div> </section> <section class="elementor-section elementor-top-section elementor-element elementor-element-9b04367 elementor-section-boxed elementor-section-height-default elementor-section-height-default" data-id="9b04367" data-element_type="section"> <div class="elementor-container elementor-column-gap-default"> <div class="elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-0fc999f" data-id="0fc999f" data-element_type="column"> <div class="elementor-widget-wrap elementor-element-populated"> <div class="elementor-element elementor-element-1e232f1 elementor-widget elementor-widget-menu-anchor" data-id="1e232f1" data-element_type="widget" data-widget_type="menu-anchor.default"> <div class="elementor-widget-container"> <div class="elementor-menu-anchor" id="what-are-the-signs-of-a-ddos-attacks"></div> </div> </div> </div> </div> </div> </section> <section class="elementor-section elementor-top-section elementor-element elementor-element-be74c73 elementor-section-boxed elementor-section-height-default elementor-section-height-default" data-id="be74c73" data-element_type="section"> <div class="elementor-container elementor-column-gap-default"> <div class="elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-f31f53e" data-id="f31f53e" data-element_type="column"> <div class="elementor-widget-wrap elementor-element-populated"> <div class="elementor-element elementor-element-4d5a7cd elementor-widget elementor-widget-heading" data-id="4d5a7cd" data-element_type="widget" data-widget_type="heading.default"> <div class="elementor-widget-container"> <h3 class="elementor-heading-title elementor-size-default">What are the signs of a DDoS attacks?</h3> </div> </div> <div class="elementor-element elementor-element-e46e696 elementor-widget elementor-widget-text-editor" data-id="e46e696" data-element_type="widget" data-widget_type="text-editor.default"> <div class="elementor-widget-container"> <p>The<span style="color: #028673;"> </span><a href="https://blog.sucuri.net/2021/04/how-to-know-if-you-are-under-a-ddos-attack.html"><span style="color: #028673;">signs of DDoS attacks</span> </a>include:</p><ul><li>The website is responding slowly.</li><li>The website is unresponsive.</li><li>The user has problems accessing the website.</li><li>Internet connection issues if you are a target.</li><li>Any type of disruption, depending on your configuration, can be devastating to your business.</li></ul><p>Skip to section 4 to learn some of the reasons why.</p> </div> </div> </div> </div> </div> </section> <section class="elementor-section elementor-top-section elementor-element elementor-element-554cf11 elementor-section-boxed elementor-section-height-default elementor-section-height-default" data-id="554cf11" data-element_type="section"> <div class="elementor-container elementor-column-gap-default"> <div class="elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-8f63cf1" data-id="8f63cf1" data-element_type="column"> <div class="elementor-widget-wrap elementor-element-populated"> <div class="elementor-element elementor-element-af98c8b elementor-widget elementor-widget-menu-anchor" data-id="af98c8b" data-element_type="widget" data-widget_type="menu-anchor.default"> <div class="elementor-widget-container"> <div class="elementor-menu-anchor" id="the-amplification-effect-of-a-ddos-attack"></div> </div> </div> </div> </div> </div> </section> <section class="elementor-section elementor-top-section elementor-element elementor-element-3cf476c elementor-section-boxed elementor-section-height-default elementor-section-height-default" data-id="3cf476c" data-element_type="section"> <div class="elementor-container elementor-column-gap-default"> <div class="elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-db79068" data-id="db79068" data-element_type="column"> <div class="elementor-widget-wrap elementor-element-populated"> <div class="elementor-element elementor-element-d727221 elementor-widget elementor-widget-heading" data-id="d727221" data-element_type="widget" data-widget_type="heading.default"> <div class="elementor-widget-container"> <h3 class="elementor-heading-title elementor-size-default"> The amplification effect of DDoS attacks</h3> </div> </div> <div class="elementor-element elementor-element-5039ea3 elementor-widget elementor-widget-text-editor" data-id="5039ea3" data-element_type="widget" data-widget_type="text-editor.default"> <div class="elementor-widget-container"> <p>Every time we talk about DDoS attacks, we have to mention its<strong> amplification effect</strong>. In order to achieve amplification, most attackers leverage <span style="color: #028673;"><a style="color: #028673;" href="https://blog.sucuri.net/2015/08/funwebproducts-useragent-bloating-traffic.html">botnets consisting of compromised computers</a></span>, allowing them to amplify their attack across the size of the botnet. One attacker can control 1,000 bots which can then be used to DDoS the victim. That’s 1,000 bots vs. 1 server, making it easier for the attacker to win. However, not always do attackers need to be in control of the botnets. They can also make a host send a response to a wrong destination. For example, vulnerable <a href="https://githubengineering.com/ddos-incident-report/"><span style="color: #028673;">memcached servers were used to take Github down</span></a> and none of them were actually hacked, only fooled by the attacker.</p><p>The other aspect of amplification has to do with the <strong>network layer</strong> and spoofed requests. What if each computer on the botnet only needs to send 1 byte to get a 100 byte response? That’s called a <strong>100x amplification</strong>. When the request is spoofed, the reply goes back to someone else on the internet, not the attacker. This means that the network port of the server is processing the 1 byte incoming <strong>+ 100 bytes outgoing</strong>, while the attacker only processes the 1 byte outgoing on their end.</p><p>A theoretically small botnet of 1,000 bots can easily generate close to <strong>100 Gbps</strong> when using the right amplification method.</p><p>Amplification does not stop there. Most people tend to think of them only in terms of Gigabytes of network, but there is also something happening at the application layer.</p><p>What if, with just 1 HTTP request from the botnet the attacker can force a web application to do a lot of work? Like an expensive search or something that takes lots of resources?

The goal of this type of attack is to overload the website’s bandwidth or cause CPU or IOPS usage issues.</p><p>The attacker employs a basic tactic – more resources wins this game. If they can overload your resources, the attack is successful.</p><p>It is quite easy for attackers to achieve their goals. Most website owners are leveraging shared hosts and the ones with virtual private server (VPS) environments are often set up in the smallest tiers and configurations.</p><p>This attack can be measured in bits per second.</p><p>Volume-based DDoS attacks include:</p><h4>UDP floods</h4><p>The User Datagram Protocol (UDP) DoS attack will flood various ports at random, leading the host server to report back with an Internet Control Message Protocol (ICMP) packet. This is a protocol used to generate error messages to the IP address when problems prevent IP packets delivery. The UDP floods are done via packets – also known as Layer 3 / 4 attacks. This forces the web server to respond, in turn chewing through your web server resources forcing it to come to a halt or die completely. UDP is a connectionless protocol, meaning it doesn’t validate source IP addresses. It’s because of this that UDP attacks are often associated with Distributed Reflective Denial of Service (DRDoS) attacks.</p><h4>ICMP floods</h4><p>Attackers flood the server with spoofed ICMP packets sent from a huge set of source IPs. The result of this attack is the exhaustion of server resources and failure to process requests, causing the server to reboot or lead to an extensive impact on its performance. ICMP flood attacks can be targeted at specific servers or they can be random. It essentially consumes bandwidth to the point of exhaustion.</p><h4>Ping floods</h4><p>Attackers flood the server with spoofed ping packets from a huge set of source IPs. It is an evolution of the ICMP flood attacks. The attacker’s objective is to flood the server until it goes offline. The biggest downside from this attack for website owners is that it can be difficult to detect, mistaken for legitimate traffic.</p> </div> </div> </div> </div> </div> </section> <section class="elementor-section elementor-top-section elementor-element elementor-element-b8ccd79 elementor-section-boxed elementor-section-height-default elementor-section-height-default" data-id="b8ccd79" data-element_type="section"> <div class="elementor-container elementor-column-gap-default"> <div class="elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-6fcdf88" data-id="6fcdf88" data-element_type="column"> <div class="elementor-widget-wrap elementor-element-populated"> <div class="elementor-element elementor-element-8bb4ccb elementor-widget elementor-widget-menu-anchor" data-id="8bb4ccb" data-element_type="widget" data-widget_type="menu-anchor.default"> <div class="elementor-widget-container"> <div class="elementor-menu-anchor" id="protocol-based-ddos-attacks"></div> </div> </div> </div> </div> </div> </section> <section class="elementor-section elementor-top-section elementor-element elementor-element-c6787b8 elementor-section-boxed elementor-section-height-default elementor-section-height-default" data-id="c6787b8" data-element_type="section"> <div class="elementor-container elementor-column-gap-default"> <div class="elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-2639c52" data-id="2639c52" data-element_type="column"> <div class="elementor-widget-wrap elementor-element-populated"> <div class="elementor-element elementor-element-f7f7c21 elementor-widget elementor-widget-heading" data-id="f7f7c21" data-element_type="widget" data-widget_type="heading.default"> <div class="elementor-widget-container"> <h3 class="elementor-heading-title elementor-size-default">Protocol-based DDoS attacks</h3> </div> </div> <div class="elementor-element elementor-element-e0220e5 elementor-widget elementor-widget-text-editor" data-id="e0220e5" data-element_type="widget" data-widget_type="text-editor.default"> <div class="elementor-widget-container"> <p>The internet is based on protocols. It’s how things get from point A to point B. DDoS attacks based on protocols exploit weaknesses in Layers 3 and 4 protocol stacks. This type of attack consumes the server resources, or any other network hardware, in the middle of processing capacities. The result is service disruption.</p><p>These attacks try to exploit your network stack by sending either more packets than what your server can handle or more bandwidth than what your network ports can handle.</p><p>The attacks can be measured in packets per second (Pps).</p><p>Protocol-based DDoS attacks include:</p><h4>Ping of Death</h4><p>Attackers send malicious pings to a server, manipulating the IP protocols. This attack was very common in the 1990s. Nowadays, even though attacks have evolved, there are some forms of Ping of Death attacks that can be targeted at applications or hardware. The result of this attack is the reboot or complete crash of the server. That is exactly why a DoS attack cannot be devalued: a single attacker could take a complete data center down.</p><h4>SYN Flood</h4><p>Attackers exploit weaknesses in the Transmission Control Protocol (TCP) connection three-way handshake, which is the communication process between the client, the host, and the server. Attackers send SYN packets to the aimed server as a spoofed message until the table memory connection of the server is exhausted causing the entire service to shut down.</p> </div> </div> </div> </div> </div> </section> <section class="elementor-section elementor-top-section elementor-element elementor-element-0083887 elementor-section-boxed elementor-section-height-default elementor-section-height-default" data-id="0083887" data-element_type="section"> <div class="elementor-container elementor-column-gap-default"> <div class="elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-8d0ed3b" data-id="8d0ed3b" data-element_type="column"> <div class="elementor-widget-wrap elementor-element-populated"> <div class="elementor-element elementor-element-1378793 elementor-widget elementor-widget-menu-anchor" data-id="1378793" data-element_type="widget" data-widget_type="menu-anchor.default"> <div class="elementor-widget-container"> <div class="elementor-menu-anchor" id="application-layer-attacks"></div> </div> </div> </div> </div> </div> </section> <section class="elementor-section elementor-top-section elementor-element elementor-element-10ea185 elementor-section-boxed elementor-section-height-default elementor-section-height-default" data-id="10ea185" data-element_type="section"> <div class="elementor-container elementor-column-gap-default"> <div class="elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-2f9ca28" data-id="2f9ca28" data-element_type="column"> <div class="elementor-widget-wrap elementor-element-populated"> <div class="elementor-element elementor-element-dc43965 elementor-widget elementor-widget-heading" data-id="dc43965" data-element_type="widget" data-widget_type="heading.default"> <div class="elementor-widget-container"> <h3 class="elementor-heading-title elementor-size-default">Application layer attacks</h3> </div> </div> <div class="elementor-element elementor-element-50936d7 elementor-widget elementor-widget-text-editor" data-id="50936d7" data-element_type="widget" data-widget_type="text-editor.default"> <div class="elementor-widget-container"> <p>The basis for this attack often targets applications like Web Servers (i.e., Windows IIS, Apache, etc…); however, application layer attacks have been evolving to application platforms like WordPress, Joomla, Drupal, Magento, and others.</p><p>The goal of application layer attacks is to take out an application, an online service, or a website.</p><p>These attacks are usually smaller than the ones we have seen before. Nevertheless, the consequence of an application layer attack can be nefarious, since they can go unnoticed until it is too late to react. That is why they are called “low and slow attacks” or even “slow-rate attacks”. They can be silent and small, especially when compared to network-layer attacks, but they can be just as disruptive.</p><p>For example, a small VPS on Linode, Digital Ocean or AWS (Amazon) can easily handle a 100,000 to 200,000 packets per second SYN flood. However, the same server running on a WordPress or Joomla CMS can barely break 500 HTTP requests per second without shutting down. That is why application layer attacks can cause as much damage as a network application attack.</p><p>When you think about the amplification effect that we discussed in Section 1.4, even one HTTP request (which an attacker can perform without spending much money or resources) can cause a server to execute a large number of internal requests and load numerous files to create the page.</p><p>Application-layer attacks (mostly known as Layer 7 attacks) can be part of attacks which not only target the application, but also the bandwidth and network.</p><p>One of the reasons why these attacks are on the rise is that they tend to be less expensive to implement by malicious actors. On an application-layer attack, the amplification is CPU, <strong>memory</strong> or <strong>resource based</strong>, not network based.</p><p>These attacks are also harder to detect than network-layer attacks.</p><p>Your devices, such as home routers, can be compromised and act as a botnet for DDoS attacks. We have discovered a number of large-scale DDoS attacks related to IoT devices.</p><p>Application Layer Attacks include:</p><h3>Attacks targeting the DNS server:</h3><p>The Domain Name System (DNS) is vital to the website infrastructure. DNS associates information with domain names and they can also be a target of DDoS attacks.</p><p>These attacks use spoofing, reflection, and amplification, which means that a tiny query can be largely amplified in order to result in a much larger response in bytes.</p><p>Botnets are used to send DNS requests. If the attacker wanted to target a DNS server, it would use all the botnet zombies in his network to issue DNS request messages for an amplification record from open recursive DNS servers that translate domain names into IP addresses. When it is a new request, the server promptly issues its own request to an infected server with a view to obtain the amplification record. This attack is completed using spoofing so that even though the server has never sent a request, it has been overburdened with responses.</p><p>These attacks are very popular today. They occur at Layers 3 / 4, using publicly accessible DNS servers around the world to overwhelm your web server with DNS response traffic. Your web server is overwhelmed by the influx of responses in turn making it difficult to function as its resources are depleted, making it impossible to respond to legitimate DNS traffic.</p><p>A Layer 3 DNS Amplification is a type of DDoS attack where the attacker hides the origin of the attack from the targeted site by reflecting the attack off of a third party. It uses amplification, meaning that the victim receives more byte counts than what is being sent from the attacker, increasing the power of the attack.</p><p>If these attacks are successful, the targeted site will go down and be unavailable.</p><h3>Layer 7 HTTP Flood – Cache Bypass:</h3><p>Layer 7 HTTP Flood – Cache Bypass is the smartest type of attack. The attackers try to use URLs that cause the most damage making the site use up all of its resources without being cached. For example, an attack can do random dictionary searches for “news”, “gov”, “faith”, which will consume a lot from the site and will not easily be detected since it looks like a normal user’s search habits.</p><h3>Layer 7 HTTP Flood Attack:</h3><p>A Layer 7 HTTP Flood Attack is a type of DDoS attack made to overload specific parts of a site or server. They are complex and hard to detect because the sent requests look like legitimate traffic. These requests consume the server’s resources causing the site to go down. These requests can also be sent by bots, increasing the attack’s power.</p><p>An interesting point about layer 7 DDOS attacks, aka HTTP flood attacks, is that they have little dependency on bandwidth allowing them to easily take down a server by overloading its resources. Depending on the web server and application stack, even a low number of requests per second can choke the application and backend databases. On average, attacks greater than 100 requests per second have the potential to bring down most mid-sized websites.</p><p>The issue with this type of attack is that server-level caching is unable to stop it. The incoming URLs are dynamic and the application forces a reload of the content from the database for every new request that is not in cache, which creates a new page. Attackers know this, <br /><a href="https://blog.sucuri.net/2014/02/layer-7-ddos-blocking-http-flood-attacks.html"><span style="color: #028673;">making it the preferred method of attack for today’s Layer 7 DDoS attacks</span></a>.</p><p>We categorize the HTTP Floods (Layer 7 DDoS attempts) into 4 major categories:</p><ul><li><strong>Basic HTTP Floods:</strong> Common and simple attacks that try to access the same page over and over. They generally use the same range of IP addresses, user agents, and referrers.</li></ul><ul><li><strong>Randomized HTTP Floods:</strong> Complex attacks that leverage a large pool of IP addresses and randomized the URLs, useragents and referers used.</li></ul><ul><li><strong>Cache-bypass HTTP Floods:</strong> A sub-category of the randomized HTTP Floods that also try to bypass web application caching.</li></ul><ul><li><strong>WordPress XMLRPC Floods:</strong> A sub-category that uses WordPress pingback as a reflection for the attacks.</li></ul><p>Any WordPress site with pingback enabled, which is on by default, can be used in DDoS attacks against other sites.</p><p>XMLRPC is used for pingbacks, trackbacks, remote access via mobile devices and many other features. However, it can also be heavily misused by attackers.</p><p>What can happen is that other WordPress sites can send random requests at a very large scale and bring a website down.</p><p>One attacker can use thousands of clean WordPress installations to perform a DDoS attack with a simple pingback request to the XML-RPC file. In other words, a simple command in Linux can start a mammoth attack.</p><p>If you are interested in learning more about legitimate WordPress websites being abused in order to perform a DDoS attack,
