The DDoS Attacker’s Playbook: What You Need to Know to Stay Safe

No business wants to be the victim of a Distributed Denial of Service (DDoS) attack, but it’s important to be aware of the different types of attacks that exist and how they work. In this blog post, we’ll explain what DDoS attacks are and provide an overview of the various types of DDoS attacks that exist. Some recent examples of notable DDoS attacks are the Dyn DNS attack in 2016, GitHub attack in 2018, and the Microsoft Wynncraft botnet attack in 2022. These attacks are becoming more frequent and sophisticated every day; they can lead to service outages and extortion attempts as well as damaging a company’s reputation. The worst part? Most of these attacks are entirely preventable if you have the proper cybersecurity measures in place.

What is DDoS Attack?

A DDoS attack is a type of cyberattack that involves flooding a target server with traffic designed to cause it to become overwhelmed and unable to service legitimate requests. This flood of traffic can be the result of multiple devices connected to the internet trying to send data at the same time. However, the most common method used is malware distributed on devices infected with botnet malware. This type of attack can be costly and time-consuming for businesses, government agencies, and other organizations. The type of attack varies depending on the type of network system being targeted, such as web server, application server, or network device.

Cybercriminals attack organizations in a large sweep to seek out easy targets to exploit. If you’re a company not well equipped to withstand a DDoS attack, attackers will choose you as their next target. However, if you’re prepared for a DDoS attack, you’re less likely to be targeted. Cybercriminals seek quick gains with the least number of obstacles. This makes it essential for every organization to understand the different types of DDoS attacks and how to prevent them from happening.

Some of the most popular types of industries for DDoS attacks include the telecommunications sector, financial sector, gaming, online casinos, online gambling, online poker, online bookmakers, online betting, brokerage firms, online stock trading sites and any organization with notoriety within the global community. Preparing for a DDoS attack can help you to avoid costly downtime and repair fees.

Types of DDoS Attacks

Network Flood

This type of attack is malicious users attempting to flood your network with excessive traffic. The primary goal of this attack is to slow down or interrupt your network and cloud computing and overload your router or computer. Network flood attacks typically use automated tools that target as many IP addresses as possible.

UPD Flood

An application-level flood attack targets specific ports on servers. These attacks flood servers with UDP packets to disrupt their processing.

SYN Flood

In this type of DDoS attack, malicious users send fake requests for connections that are SYN packets. This can create a false connection on the target network and consume the bandwidth.

HTTP Flood

This attack type floods servers with HTTP requests and consumes the RAM and CPU resources.

DNS Flood

In this attack, malicious users attempt to flood the target with DNS requests to shut down the server.

SOCKS5 Flood

SOCKS5 floods target specific services and try to consume resources.

Volumetric Attack

This attack attempts to send too much traffic to the target system and overwhelm it.

Application Layer Attack

This type of attack focuses on the application layer of a network.

HTTP Request Flood

This happens when spammers send too large of requests and consume resources.
