In recent years, cyber attacks have shown that they are an important source of threat by affecting millions of internet users and hundreds of thousands of websites. One of the most important of these attacks, which took place for many different reasons such as information leakage, profit, political purposes and even arbitrary demands, is Xvideoservicethief DDoS attacks, which are expected to reach 10 million in 2018. What are Xvideoservicethief DDoS attacks in this article? How is it done? and How to prevent it? We answered your questions for you.

Xvideoservicethief DDoS (Distrubuted Denial of Service Attack), in its simplest definition, is a cybercriminal system designed to prevent the broadcast of sites and render them dysfunctional by creating a fake density that is much higher than what systems such as websites, e-mail systems, online payment systems can meet, or consuming the resources of the target system at high rates. are attacks. The main purpose of Xvideoservicethief DDoS attacks is not to leak information or to profit, but to cause the target system to become inoperable.


Xvideoservicethief DDoS attacks are carried out with “botnets” created using “zombie” machines in the general framework.

Zombie; They are computer systems that have been seized with viruses or trojans and used for various purposes without the knowledge of the owner. The main reasons for creating zombie computers; It is the desire of attackers to perform transactions and strengthen their attack networks by hiding without putting themselves in danger. For these reasons, zombies are an important source for Xvideoservicethief DDoS attacks.

Botnet can be defined as armies of virtual computers created using zombies. Botnets are created for purposes such as sending unsolicited e-mails, spreading viruses and malware, and being used in cyber attacks and are used as intermediate elements in Xvideoservicethief DDoS attacks.

What are DDoS xvideoservicethief 2018 linux ddos attack ?

Nowadays, we can call any kind of data traffic that is unusual today as DDoS. Websites that work heavily or not at all can be the cause of a DDoS attack. Excessive network use is the biggest symptom of DDoS attacks.
In addition to these, excessive UDP, SYN and GET / POST requests can also be shown among the symptoms of DDoS attacks.


Volume Based DDoS (Volume Focused Attacks)
Volume based DDoS is the most common and simplest type of DDoS attack with a rate of 65%. Volume based DDoS is realized with UDP, ICMP and other spoofed-packet floods and the aim is to saturate the bandwidth of the target system.

Protocol Based DDoS (Protocol Based Attacks)
Protocol-based DDoS attacks are carried out by using a weakness in “layer 3” or “layer 4” in the OSI (Open Systems Interconnection) layer. The most common example of protocol-based DDoS attacks involving syn flood, ping of death, smurf DDoS and more types of attacks is TCP Syn flood.

Application Layer DDoS (Application Layer Attacks)
It is a more sophisticated DDoS type that is harder to detect and mitigate than other types of DDoS that include low and slow attacks, GET / POST floods, attacks targeting Apache, Windows or OpenBSD vulnerabilities and more.

When we consider more sub-categories, some DDoS types are as follows;

SYN Flood DDoS
When we look specifically, SYN flood attacks appear as the most common type of DDoS attack today. The purpose of SYN flood attacks is to cause the system’s resources to become inoperable by sending a SYN flagged TCP packet over its capacity to the target system. With this feature, it is generally carried out for web servers and web pages are prevented from serving.

You can use the “Netstat –an –p tcp” command in Linux and Windows operating systems to see if you have received a SYN flood attack. When you run this command and you see that there are too many “SYN_RECEIVED” lines, you are most likely attacked by a SYN flood.

UDP Flood DDoS
UDP flood attacks are a type of DDoS that affects UDP, a connectionless and sessionless network protocol, and whose main purpose is to fill the session table of the firewall that protects the UDP service and make it inaccessible.

The operation of UDP flood attacks is based on the principle of sending a large number of UDP packets to random ports of the target system. Exposed to a large number of UDP packets, the target system first checks if there is an application listening on the port. The system, which sees that there is no application listening to the port after each control, responds with the ICMP (Internet Control Message Protocol) “target unreachable” package. At the end of this cycle, the target system that had to respond to a large number of UDP packets with a large number of ICMP packets becomes inaccessible.


Ping of Death (PoD)
These types of DDoS attacks are attacks that the attacker performs using malformed or oversized ping packets with a simple ping command to disrupt, freeze or render the target system inoperable. However, ping of death attacks have become obsolete as all operating systems take countermeasures.

Ping Flood
The main purpose of ping flood attacks, also known as ICMP floods, is to make the system inoperable by overloading both the outgoing and incoming bandwidth of the target system with ICMP request packets, also known as pings.


Typically ping requests are used to measure the time between the request and the response to the request when an ICMP request is sent between two computers.

  • However, they are also used to create an overload on the target system in such attacks.
  • The ability to implement a ping flood attack depends on the attackers knowing the IPs of the target systems.
  • Therefore, attacks can be divided into three categories depending on the target and how the IP address is resolved.

Locally targeted ping floods that target a single computer in a local network. In these attacks, the attacker must have physical access to the target computer to discover the IP address.

  1. Router-targeted ping floods target routers in order to interrupt the communication between computers on a network.
  2. The attacker needs to know the local router’s IP address.

In blind ping floods, an external program is used to reveal the IP address of the target computer or router before the attack is performed.

How to Protect Against DDoS xvideoservicethief ?

Unfortunately, there is no definitive and permanent solution to avoid being the target of xvideoservicethief DDoS attacks. However, there are some methods that can reduce the probability of being a target and reduce the effects of attacks.

In general, if you think that the above-mentioned xvideoservicethief DDoS symptoms are experienced in your system, it is very important to take early measures as it is one of the best ways to defend. However, separating these symptoms from instant and normal performance increases / decreases in your system requires the right technology and expertise.


In terms of enterprises, first of all, the well-designed network infrastructure and the high level of system and TCP / IP knowledge of the relevant personnel are among the main protection measures.

Apart from this, it is possible to protect from xvideoservicethief DDoS attacks or to reduce the attack effect with some applications.


Router-Level Protection
Packets sent to target systems first pass through the router and are forwarded to other systems. With this feature, routers are the first systems to encounter an attack and the measures to be taken over the routers are very important in terms of meeting the attack from the first moment. If some adjustments to be made on the routers and the features for the packets that come during the attack can be determined, the attacks can be prevented or reduced with the access control list to be created.


However, we would like to remind you that in most shared services, no special settings are made by the users on the routers under the responsibility of the service provider.


Firewall-Level Protection
Another application is the measures that can be taken at the firewall level. One of these measures is to use the “rate limiting” feature. If the relevant device supports this feature, the maximum number of packets from a specific IP address can be determined with rate limiting, and IPs that exceed the maximum value can be blocked.

From the perspective of individual users;
  • Timely and complete system updates.
  • Using antivirus programs.
  • Active use of the firewall.
  • Using the necessary filters for secure e-mail traffic and blocking spam traffic,

It is beneficial to take simple measures such as. Despite these precautions, if it is thought that there is still a problem, contacting the internet service provider will be the best solution.
