For creating the zombie network, hackers generally use a Trojan. The more members in the zombie network, more powerful the attack it. In this case, blocking a single or few IP address does not work. In simple words, when a server system is being flooded from fake requests coming from multiple sources (potentially hundreds of thousands), it is known as a DDOS attack. Whenever he wants to perform DDOS, he can use all the computers of ZOMBIE network to perform the attack. To perform a DDOS attack, attackers use a zombie network, which is a group of infected computers on which the attacker has silently installed the DOS attacking tool. As the DOS attack is distributed over large group of computers, it is known as a distributed denial of service attack. In DDOS attacks, many computers start performing DOS attacks on the same target server. This is the complicated but powerful version of DOS attack in which many attacking systems are involved. The second form of DOS attack only floods a service.ĭDOS or Distributed Denial of Service Attack The first form is on that can crash a server. In general, there are two forms of the DOS attack. We will also see how to prevent this attack and how not to be the part of this attack. In this post, we will see more about the DOS attack, its variants, and the tools that are used to perform the attack. But a widespread and clever DOS attack can bypass most of the restrictions. This tool can be blocked easily by having a good firewall. In past few years, the use of the attack has increased due to the availability of free tools. It causes service outages and the loss of millions, depending on the duration of attack. This attack is one of most dangerous cyber attacks. Don’t confuse a DOS attack with DOS, the disc operating system developed by Microsoft. The denial of service (DOS) attack is one of the most powerful attacks used by hackers to harm a company or organization. After this, server will not be able to handle the requests of legitimate users. This is achieved by flooding the server’s request queue with fake requests. A DOS attack is an attempt to make a system or server unavailable for legitimate users and, finally, to take the service down.
