Focus on. These attacks attempt to deny service to devices such as firewalls or default TCP \/ IP stacks running on servers. They maliciously exploit the weakness of the way the server’s network stack processes network packets or the way TCP communication works. Examples of protocol based DDoS attacks are as follows:
As can be expected, attackers are not limited to one type of attack: DDoS attacks using multi vector methods are becoming more and more common. Multi vector DDoS attack is a kind of DDoS attack, which uses a variety of technologies to take the target offline. To understand the reflection and amplification of DDoS, two terms that often appear in DDoS attacks are reflection and amplification. Both technologies are used by attackers to create DDoS attacks more effectively. Redirection is a technique that sends a request containing the IP address dumped by the attacker to a third-party server. The IP address of the dump is the address of the destination. In this type of attack, attackers usually use multiple UDP protocols. The working principle is as follows:
An attacker sends a UDP request containing a dump IP address (such as the IP of a WordPress site) to many servers called redirectors. Replicator receives the request and responds to the IP address of the WordPress site. The replicator response overflows the WordPress site, causing potential overload and making it unavailable. Magnification works like reflection. The request sent to replicator is much smaller than the response sent by replicator to the target, so it requires less bandwidth and resources. This is similar to what you see in application layer distributed denial of service attacks.
Do you want to know the role of Botnet in DDoS attack? Where does the attacker get resources to adjust the attack? The correct answer is four robots. Botnets are networks or devices damaged by malware. PC, server, network or intelligent device. Malware allows attackers to remotely control each infected host. If used for DDoS, the botnet will perform an adjusted denial of service attack on the specified target host or host group. In short: through botnets, attackers can use the resources of infected computers to carry out attacks. For example, in 2018, more than 20000 WordPress sites were used to carry out DDoS attacks on other WordPress sites (see details).
Motivation for distributed denial of service attacks: \
Of course, one of the biggest motives is money. An attacker can ask for ransom to stop the WordPress website attack. If your site goes down, you can benefit from business. Further, we have DDoS for employment services! How serious is the actual pre distributed denial of service attack of distributed denial of service? Let’s take a look at the famous DDoS attacks in the past few years. GitHub (twice!): GitHub suffered a massive denial of service attack in 1015. The attack appears to target two anti censorship projects on the platform. The attack took a few days
Make sure you use a strong password. In addition, install the dual authentication plug-in and implement a policy that enforces dual authentication.
