Best Free DoS Attacking Tools

A Denial of Service (DoS) attack is planned to trigger service outages. Even if the attacker does not demand a ransom to stop the attack, these attacks can easily cost a company a large amount of damage and waste money. There is a range of different free DDoS methods, making it cheap and simple for this attack strategy to be used by even unsophisticated attackers.

The following are facts about DoS attacks:

• DOS (Denial of Service) is an attack carried out on a device or network that prevents users from being able to access machine resources.
• The attacker overloads his resources and malicious traffic inundates the victim machine.
• A website can suffer temporary or permanent damage from a DOS attack. It can slow down network efficiency as well.

Attacking tool considerations

• Is the tool a regular construction or the work of a kiddie or self-written script?
• What is the attack tool's target?
• Is the method capable of producing DoS attacks of different kinds?
• Can you configure the traffic according to need, such as NO requests/sec and choice of protocol?
• Is it easy to use the tool? Are you a GUI lover or command line fan?
• Effectivity? The attack is sufficiently successful to be called an attack or only high traffic.
• Any patterns of traffic and stealth techniques used? If the attack traffic is readily identified and blocked by traditional techniques, there is no point in using a tool. Is the instrument to cover the attack traffic using fragmentation and obfuscation techniques?

5 Best Free DoS Attacking Tools

A variety of different attack methods are available on the internet for free. As security analysts and network engineers conduct stress tests on their networks, some of these methods have valid uses. Some attack instruments are specialized and concentrate only on a single region of the protocol stack, while others are designed to allow multiple vectors of attack.

LOIC (Low Orbit Ion Cannon)

LOIC is one of the most common tools freely accessible on the internet to attack DoS. Not only did the tool use the popular hacking group Anonymous, but internet users were also invited to enter their DDoS attacks via IRC.

A single user may use LOIC to execute a DoS assault on small servers. Also, for a beginner, this method is very easy to use. By sending UDP, TCP or HTTP requests to the victim's server, this tool executes a DoS attack. You just need to know the server's URL or IP address and the tool will do the rest.

This tool also has a mode for HIVEMIND. To execute a DDoS attack, it requires attackers to monitor remote LOIC systems. This function is used in your zombie network to monitor all other computers. This tool can be used against any website or server for both DoS attacks and DDoS attacks.

LOIC does nothing to cover your IP address, which is the most important thing you should remember. Think again if you are going to use LOIC to execute a DoS attack. It won't benefit you to use a proxy, since it will reach the proxy server, not the goal server. This method can only be used to test your own systems' durability against DoS and DDoS attacks.

Restrictions

• The IP address is revealed, making it easy to locate the intruder
• The IDS/IPS/AV detects it easily
• Unable to execute DDoS attacks
• Many goals cannot be targeted at once

XOIC

Another great DoS attacking tool is XOIC. When the user can include an IP address, a target port and a protocol to use in the attack, it performs a DoS attack against any server. XOIC developers say that in many respects, XOIC is more powerful than LOIC. It comes with an easy-to-use interface, much like LOIC, so a novice can easily use this tool to carry out attacks.

The tool comes with three attacking modes in general. The first one is very simple, known as test mode. The second is the default mode for DoS attacks. A DoS attack mode that comes with a TCP/HTTP/UDP/ICMP message is the last one.

Restrictions

• No sophisticated features to mask the traffic.
• Easily identified and blocked

HULK (HTTP Unbearable Load King)

HULK is another nice DoS attack tool that creates a unique request to the web server for every request, making it harder for the server to detect trends within the attack. This is just one of the forms in which within its attacks, HULK destroys patterns.

It has a list of recognized user agents with requests to be used randomly. It also utilizes referrer forgery and can bypass caching engines; thus, it hits the resource pool of the server directly.

Restraints 

• HULK traffic can be analyzed and correct rules can be made to block the attack.

DDoSIM 

Another common DoS attacking tool is DDoSIM. It is used to carry out DDoS attacks by simulating multiple zombie hosts, as the name implies. Full TCP connections to the target server are provided by all zombie hosts. It is written in C++; this tool runs on Linux systems.

These are DDoSIM's main features:

• Simulates an attack by multiple zombies
• Random IP addresses
• TCP-attacks based on connections
• DDoS application-layer assaults
• DDoS HTTP with legitimate requests
• HTTP DDoS (similar to a DC++ attack) with invalid requests
• SMTP DDoS SMTP
• Flood of TCP connections on a random port

R-U-DEAD-YET

R-U-Dead-Yet (RUDY) is a POST DoS attack tool for HTTP. It is often referred to as RUDY. It performs a DoS attack via the POST method with a long-form field submission. This tool comes with an interactive console menu. It detects forms on a given URL and allows users to pick which forms and fields for a DoS attack based on a POST should be used.

Prohibitions

• Time is consuming because the attack rate is slow.
• Operates on layer 7 only (HTTP based).
• For the attack to run, the website should have form submissions.
• It is possible to detect slow data as irregular traffic and can block it.
