What Is A Layer 7 Ddos Attack

How To Stop DDOS Attacks on Your Minecraft Server (TCPShield Setup Guide!)

A layer 7 DDoS attack is a DDoS attack that sends HTTP/S traffic to consume resources and hamper a websites ability to delivery content or to harm the owner of the site. The Web Application Firewall service can protect layer 7 HTTP-based resources from layer 7 DDoS and other web application attack vectors.

Random Recursive Get Flood

This attack is a purpose built variation of Recursive GET attack. It is designed for forums, blogs and other websites that have pages in a sequence. Like Recursive GET it also appears to be going through pages. Since page names are in a sequence, to keep up appearance as a legitimate user, it uses random numbers from a valid page range to send a new GET request each time.

Random Recursive GET also aims to deflate its targets performance with a large number of GET requests and deny access to real users.

What To Do When You Are Ddosd

As discussed in other articles , a DDoS attack is a massive assault on a system to degrade its performance. The attacker hopes to make it unavailable to its intended users.

How do I know I am under DDoS attack?

If a site is sluggish, does that mean it is being DDoSed? If it is generating error codes in the 500s , is it being attacked? Not necessarily, but it might.

Sometimes, DDoS attacks are obvious. Most attackers are not altruistic , and DDoS extortion is common. So, when your site goes down and then you get a ransom demand , its clear what is happening.

Other attacks wont be as obvious, but you can still figure out the most likely explanation. For example, if there is a nation that has a grudge against your country, and your site is being overwhelmed with traffic from IP addresses within that other nation, then this is probably a politically-motivated DDoS.

Its also possible to be involved in a DDoS, but not as the victim. The D in DDoS stands for Distributed, because many computers are used to attack another computer system. The owners of these slaved systems might not know that they are being used in the attack. Nevertheless, there are some telltale signs that can suggest a computer has been hijacked . If you suspect your system is being used in a DDoS attack, reach out to a company that can analyze your network and detect if there was an intrusion.

    Ddos Attacks By Competitors

    In an ideal world, your competitors would attempt to outperform you online by improving their content, SEO and conversion rate, which is the legitimate way to use your website to gain competitive advantage.

    But in some cases, competitors might take more extreme measures. A competitor might hire someone to mount a DDoS attack on your site in the knowledge that this wont only impact your website, itll also impact your business.

    In the time it takes you to get your site working again, they will be taking business from you, especially if they are running ads using your business name as a keyword. If your site isnt up and running again quickly, youll lose search ranking and may find that your competitors now rank above you on Google.

    Of course, its very difficult to prove who carried out any DDoS attack. The attack wont come from your competitors IP address! Unless you have very deep pockets, attempting to take legal action against a competitor you suspect of doing this is unlikely to be successful.

    Far better to protect yourself from the effects of an attack in the first place. And dont be tempted to mount another DDoS attack against your competitor in response. This is illegal and its far better to reassure yourself that a competitor desperate enough to use measures such as these probably wont have the longevity or reputation that your business does.

    How Do Ddos Attacks Work

    The theory behind a DDoS attack is simple, although attacks can range in their level of sophistication. Heres the basic idea. A DDoS is a cyberattack on a server, service, website, or network floods it with Internet traffic. If the traffic overwhelms the target, its server, service, website, or network is rendered inoperable.

    Network connections on the Internet consist of different layers of the Open Systems Interconnection model. Different types of DDoS attacks focus on particular layers. A few examples:

    • Layer 3, the Network layer. Attacks are known as Smurf Attacks, ICMP Floods, and IP/ICMP Fragmentation.
    • Layer 4, the Transport layer. Attacks include SYN Floods, UDP Floods, and TCP Connection Exhaustion.
    • Layer 7, the Application layer. Mainly, HTTP-encrypted attacks.

    Botnets

    The primary way a DDoS is accomplished is through a network of remotely controlled, hacked computers or bots. These are often referred to as zombie computers. They form what is known as a botnet or network of bots. These are used to flood targeted websites, servers, and networks with more data than they can accommodate.

    What Is An Ack Flood Ddos Attack

    An ACK flood attack is when an attacker attempts to overload a server with ACK packets. Like other , the goal of an ACK flood is to deny service to other users by slowing down or crashing the target using junk data. The targeted server has to process each ACK packet received, which uses so much computing power that it is unable to serve legitimate users.

    Imagine a prank caller filling up someone’s voicemail box with fake messages so that voicemails from real callers cannot get through. Now imagine that every one of those fake messages says, “Hi, I’m calling to say I received your message.” This is somewhat like what happens in an ACK flood DDoS attack.

    What Are The Three Main Types Of Ddos Attacks

    While the one-or-many distinction between DoS and DDoS attacks is clear, DDoS attacks themselves can be divided into three categories. The division is based on how the hacker achieves the goal of creating so much traffic that the target network, site, or other resource becomes inaccessible.

    Sometimes, the damage caused by a cybercriminal is not directly connected to the size of the botnet involved, but rather tied to the types of bogus requests being generated. CSO magazine listed the three types of DDoS attacks as follows:

    • Volume-based attacks are measured by the sheer amount of traffic sent to a site. The hacker behind one of these incidents is simply trying to send as many requests as possible in an allotted span of time, potentially using a vast number of captured devices to produce the necessary pings.
    • Networking-layer DDoS attacks, also known as protocol attacks, are aimed at the infrastructure behind networks. Because these attacks are more about packets of information rather than raw bits, they are measured in packets per second.
    • Application-layer attacks affect apps directly rather than compromising the infrastructure that powers those software tools. They are measured in requests per second, because hackers use their networks of computers and other devices to continuously request access to the apps services, creating too much traffic and bringing the software down.

    Making Your Server Public

    What happens when you DDoS a Minecraft server

    Public Minecraft servers can mean lots of fun. By allowing anyone to join, a larger community can be created, making the games possibilities even vaster than before.

    Problematic players can be kept out of the server by the use of the /ban command can. This will stop the specified user from joining the server, until the ban is lifted using the /pardon command.

    The administrator role, known as operator can be assigned to players using the /op command. This will give players in game access to administrative commands, such as /ban, /pardon, /stop, /kick, /gamemode. Make sure to only give people you know and trust this role, as they could temporarily ban you from the server and make undesired changes until this is fixed.

    Never give anyone access to your control panel account as this can be used to takeover the entire server with no way for you to recover it.

    How Can Ddos Attacks Be Prevented

    Equip your network, applications, and infrastructure with multi-level protection strategies. This may include prevention management systems that combine firewalls, VPN, anti-spam, content filtering and other security layers to monitor activities and identity traffic inconsistencies that may be symptoms of DDoS attacks.

    Server And Hosting Issues

    If your site is subject to regular attacks that you dont take steps to mitigate, this could lead to issues with your hosting provider.

    A good hosting provider will give you tools to secure your site against DDoS attacks but if you dont have this and youre on shared hosting, the attacks may impact other sites on the same server.

    What Is The Process For Mitigating A Ddos Attack

    The key concern in mitigating a DDoS attack is differentiating between attack traffic and normal traffic.

    For example, if a product release has a companys website swamped with eager customers, cutting off all traffic is a mistake. If that company suddenly has a surge in traffic from known attackers, efforts to alleviate an attack are probably necessary.

    The difficulty lies in telling the real customers apart from the attack traffic.

    In the modern Internet, DDoS traffic comes in many forms. The traffic can vary in design from un-spoofed single source attacks to complex and adaptive multi-vector attacks.

    A multi-vector DDoS attack uses multiple attack pathways in order to overwhelm a target in different ways, potentially distracting mitigation efforts on any one trajectory.

    An attack that targets multiple layers of the protocol stack at the same time, such as a DNS amplification coupled with an HTTP flood is an example of multi-vector DDoS.

    Mitigating a multi-vector DDoS attack requires a variety of strategies in order to counter different trajectories.

    Generally speaking, the more complex the attack, the more likely it is that the attack traffic will be difficult to separate from normal traffic – the goal of the attacker is to blend in as much as possible, making mitigation efforts as inefficient as possible.

    Rate limiting

    Limiting the number of requests a server will accept over a certain time window is also a way of mitigating denial-of-service attacks.

    Insecure Or Out Of Date Code

    Keeping your version of WordPress as well as your theme and plugins up to date wont protect you from a DDoS attack.

    But if you are attacked and the subsequent weakness of your site is used by hackers as an opportunity to gain unwanted access, they will be far less likely to succeed if your site is well managed.

    Precautions include keeping your site up to date as well as only installing plugins and themes from reputable sources. The WordPress theme and plugin directories are by far the best places to find free themes and plugins, and reputable developers will make them available there. Be careful not to install code that might cause incompatibilities with your hosting and never install nulled themes or plugins.

    Single Request Http Flood

    When defense mechanisms evolved to block many incoming packets, attacks like Single Packet HTTP Flood were designed with workarounds to dodge these defenses. This evolution of an HTTP flood exploits another loophole in the HTTP technology. Several HTTP requests can be made by a single HTTP session by masking these requests within one HTTP packet.

    This technique allows an attack to stay invisible while exhausting a servers resources by keeping packet rates within the allowed limits.

    GitHubs example shows how a timely alert can help to mitigate even large scale attacks. There were no large botnets. However, it was sending data packets at 126.9 million per second rate. Thats almost 1.4 Terabytes per second. It was executed by flooding memcached servers with spoofed requests, considerably amplifying the scale and redirecting the responses to the GitHub network. Prolexic Technologies, the DDoS mitigation providers that GitHub used, kicked in intercepting the attacks.

    The Main Types Of Ddos Attacks

    When we say a DDoS attack, it generally means a large-scale attack aimed to shut down a particular target. However, there are several variations in how DDoS attacks work. Typically, this depends on the part of the network that suffers the attack.

    Network connections consist of many components, so a DDoS attack could target any one of them to intercept the service. In the network architecture OSI model, these components are more commonly known as layers – and they help us to describe the process of connectivity:

    Application layer topmost layer that specifies protocols for interactions with the network

    Presentation layer makes sure that the data is in a standardised format that the two separate systems understand

    Session layer is a mechanism that manages open network sessions intended for particular exchanges

    Transport layer ensures the reliable arrival of messages and confirms their reception

    Network layer responsible for routing data packets through intermediaries like routers and servers

    Datalink layer organizes the data into the packets that are ready to be sent

    Physical layer defines the transmission of raw bits over physical data links

    In this sense, DDoS attacks fall into three categories: application-layer attacks, protocol attacks, and network-centric attacks, depending on which layer they target. Heres what each of them does.

    What Is The Purpose Of This Guide

    No amount of DDoS protection will help when you piss off the wrong people. Look at how Anonymous took down Sony, or simultaneously took down PayPal, Visa, and MasterCard at the same time. If major corporations with seemingly endless supply of cash can’t stay up against DDoS, nothing we do will protect you from attacks of similar calibre.

    As such, it is important to note that this guide is not designed to enable you to slap epeen at griefers, and make enemies. Instead, it is intended to help you withstand smaller DDoS attacks from competitors who decide to play dirty, and keep your server online a bit longer, instead of giving them the opportunity to think they’re pro-anonymous while screaming “#TANGODOWN” and rant about how bad or unstable your server is on other sites, in attempt to shame you out of the competition.

    It is also important to note, that by setting up proxy/relay/tunnel/etc. for DDoS mitigation, you are adding additional latency between your server, and the players, as all data must be routed through to another server. If you are intending to run a sub 100ms ping server for competitive PvP, you will not be able to achieve desired results with setup such as this, or even most DDoS mitigation services.

    Estonian Incident Of 2007

    One of the biggest DDoS attack examples can also possibly be an example of a foreign country intervention. Its one of the famous examples of Russian hackers making things worse for you in cyberspace.

    In 2007, Estonia relocated a Soviet Union monument dedicated to the soldiers who perished in World War II. Not long after, the Estonian parliament, government services, and even news media and broadcasters found themselves in the middle of a large scale DDoS attack. It widely believed that Russia had directed the attacks. However, since they didnt comply with Estonian requests to let them pursue their investigation, it remains a mystery how it happened.
