10 Best FREE DDoS Attack Tool Online (2023)
Lawrence Williams
DoS (Denial of Service) is an attack used to deny legitimate user’s access to a resource such as accessing a website, network, emails, etc. Distributed Denial of Service (DDoS) is a type of DoS attack that is performed by a number of compromised machines that all target the same victim. It floods the computer network with data packets.
There are numerous DDoS attack tools that can create a distributed denial-of-service attack against a target server. Following is a hand-picked list of the DDos Attack Tools with Popular features, Pricing, Detailed reviews, and Comparison. The list contains both open-source (free) and commercial(paid) DDoS tools.

What are DoS and DDoS attacks?
A Denial of Service (DoS) attack is a cyber attack that targets computer systems, networks, or servers intending to disrupt services and make them unavailable to users. The most common method employed in a DoS attack involves overwhelming the target with unnecessary requests, thereby causing the system to slow down or crash. This often results from the attacker exploiting certain vulnerabilities in the target system, leading to service disruption.
On the other hand, a DDoS attack is an escalated form of a DoS attack where the malicious traffic comes from multiple sources – making it harder to stop the attack simply by blocking a single source. In a DDoS attack, multiple compromised computers, collectively referred to as a botnet, are used to flood the target system with traffic, thereby causing a denial of service. These attacks are more difficult to mitigate due to their distributed nature, as the attacker controls multiple sources of the traffic.
What is DDos Attack Tool?
A Distributed Denial of Service attack tool is a specialized software designed to execute attacks on particular websites and online services. These tools often form part of a DDoos attack program that manages the operation, coordinating multiple devices infected with malware to simultaneously send requests to the targeted site, hence ‘distributed’. While these tools and programs can devastate the targeted website, their use is illegal and constitutes a serious cybercrime. The best DDoS tools, from a technical standpoint, are often sophisticated and adaptable, able to mimic legitimate traffic and bypass defenses.
How are DoS/DDoS attack tools categorized?
DoS/DDoS attack tools are categorized based on their functionalities, complexity, and the methods they employ to carry out the attacks. These categories help security professionals understand the nature of the threats and devise appropriate countermeasures. Here are the main categories of DoS/DDoS attack tools:
1. Simplicity-Based Categorization:
Basic DoS Tools: These tools are simple and require minimal technical expertise to operate. They typically include tools like Low Orbit Ion Cannon (LOIC) and High Orbit Ion Cannon (HOIC), which flood the target IP with high traffic from multiple sources.
Botnet-based Tools: More advanced attackers may use botnets, which are networks of compromised devices (often called zombies or bots) to orchestrate DDoS attacks. These botnets can be rented or created by attackers.
2. Protocol-Based Categorization:
Volumetric Attacks: These attacks focus on overwhelming the target’s network and bandwidth with massive amounts of traffic. Examples include SYN Flood and UDP Flood attacks, which exploit weaknesses in TCP and UDP protocols, respectively.
Application Layer Attacks: These attacks target specific applications or services on the target system. Examples include HTTP Flood, Slowloris, and DNS query-based attacks.
3. Reflection/Amplification Attacks:
Amplification attacks exploit vulnerable servers to amplify the volume of traffic directed at the target. Attackers send small requests to these servers, which respond with much larger replies, magnifying the attack’s impact. DNS Amplification and NTP Amplification attacks are common examples.
4. Botnet-based Attacks:
Botnet-based DDoS attacks involve coordinating a large number of compromised devices (bots) to flood the target IP with traffic. These attacks are challenging to trace back to the attacker due to their distributed nature.
5. DDoS-for-Hire Services (Booters/Stressers):
These commercial services on the dark web allow attackers to rent DDoS attack tools and services. These services offer easy-to-use interfaces and enable attackers to launch DDoS attacks without the need for technical expertise.
How DDos Attack Tools Works?
DDoS attack tools target a server or network by finding vulnerable systems within the network and injecting malware on those systems. As soon as enough devices are infected within a network, DDoS attack tools instruct each infected system to attack the server by sending a flood of requests and overloading the server or network, which results in slowdowns, denial of service, or complete failure.
