HULK is a Denial of Service (DoS) tool used to attack web servers by generating unique and obfuscated traffic volumes. The main purpose of using this tool is to disrupt online services for intended users by sending malicious requests.
HULK flood differs from most available DDoS attack tools which produced predictable repeated patterns that could easily be mitigated. The principle behind the HULK flood is that a unique pattern is generated at each and every request, with the intention of increasing the load on the servers as well as evading any intrusion detection and prevention systems.
Researchers from Kapersky Lab recently reported on a new distributed denial-of-service (DDoS) tool. The HTTP Unbearable Load King (HULK) tool is different from others of its kind in that it does not simply hit a server with a massive load of TCP SYN requests or other predictable packets. HULK generates numerous unique requests designed to prevent server defenses from recognizing a pattern and filtering the attack traffic. The HULK DDoS tool is the work of Barry Shteiman, a security pro who developed it out of frustration with the obvious patterns produced by other such tools.
In order to confuse the target Web server as thoroughly as possible, Shteiman has included a number of different features in HULK, including the ability to hide the actual user agent and obfuscate the referrer for each request. In his own tests, Shteiman said that the attack tool had no trouble taking down a target server within a minute or so.
we have all heard about the hulk tool for dosing sites but time has passed and it went hold, now it barely can hold any sites off with CDNs and Loadbalancing servers like nginx and cloudflare protecting them. well not any more, witness the power of the new and improved hulk tool version 1.0.2, available in both golang and python.
The main difference from Python version layed in Golang architecture for concurrency: the goroutines. hulk.py runs a new thread for each connection in the connection pool so it uses hundreds and thousands of threads. hulk.go just uses lightweight goroutines that used only tens of threads (commonly golang runtime started one thread for CPU core + several service threads). This architecture allows golang version better consume resources and got much higher connection pool on the same hardware than Python version can.
The tool bypasses caching engines and hits the server directly. Since its release, several actors have optimized and republished this code to include more user agents and referrers in an attempt to generate more randomized requests while launching an attack.
HULK is an abbreviation for HTTP Unbearable Load King, which is a web server Distributed Denial of Service tool. It is mainly designed for research purpose, and helps pen testers check the efficiency of a server. With its help, security specialists can find loopholes in their security implementation against DDoS, and correct them before an actual threat actor exploits it.
Barry was frustrated seeing how most of the pentesting tools generate predictable load packets or HTTP SYN requests, prohibiting security experts from checking the actual defense ability of their organizational networks. He wrote this Python script for DDoS attack testing. The purpose of its creation was to launch 'more real' attacks and test the actual efficiency of any server.
HULK is very different from regular pentesting tools, attack scripts, and exploit methods. HULL generates a number of unique requests at irregular intervals from the same host. So, not only does it run a DDoS attack, the script also tries to prevent the network's defense mechanism from guessing the attack pattern. This makes it really tough to filter the traffic/packets.
Creating various unique URLs for every request helps HULK bypass the caching tools and other filtering/optimization mechanisms. The tool, most of the time, receives a response OK (200) due to this feature.
If you see the below HULK statistics, you will be able to understand the tool is very efficient. Its efficiency is proportional to the client-side resources and number of nodes utilized to run the attack. An attack can actually last (and succeed) within 8.818 sec or less!
HULK starts a load of threads to fire off a flood of HTTP GET requests with randomly generated header and URL parameter values. This randomisation makes it more difficult to distinguish the attack from legitimate traffic. However thwarting the tool is not especially difficult, according to Prolexic.
HULK is a web server denial of service tool written for research purposes. It is designed to generate volumes of unique and obfuscated traffic at a webserver, bypassing caching engines and therefore hitting the server's direct resource pool.
SecOps (or Security Operations) is a collaborative effort between IT security and operations teams that integrates tools, processes, and technology to meet the collective goals of keeping an enterprise secure while reducing risk and improving business agility.
HULK (HTTP Unbearable Load King) generates numerous unique requests designed to prevent server defenses from recognizing a pattern and filtering the attack traffic.HULK's generated traffic also bypasses caching engines and hits the server's direct resource pool. This tool is used to test network devices like a firewall.
hping3, a Kali Linux open-source packet crafting tool, allows the type of packet to be set (TCP, UDP, and ICMP), as well as the speed at which to send them. hping3 enables the user to finely tune the speed of the packets being sent using a microsecond interval. This Active Network Smashing Tool simulates DoS attacks specifically and allows for the creation of HTTP GET and POST requests for web application attacks.
HULK was created on the premise that many DDoS tools use an easily observable pattern, thus making detection and mitigation an easier task. HULK creates a unique value for each request being sent. Specific techniques used include the following, as listed as on their website:
By incorporating these three tools into your vulnerability assessment toolkit, you can take the first step towards fortifying your organization's security posture against DDoS attacks. However, regular DDoS testing is crucial for continued protection against the ever-evolving threat landscape, reducing the risk of downtime, reputational harm, and financial losses caused by cyber attacks.

DDOS attacks are cyber- attacks targeted at rendering certain computers, network systems and servers non-functional. The processes involved in its execution can be however complicated. Attackers have to carry out a long series of actions that involve social engineering, data breaches and sometimes even system testing. Due to the sophistication of these activities, tools have been developed to facilitate DDOS attacks for pen testers. Although, it is kind of two sided, DDOS attacks tools are important for system admin and pen testers to use. It helps them carry out faster attacks to determine the strength of their server or framework security. On the other hand, hackers can also use these tools to execute their own attacks. In fact, DDOS tools are primarily used by cyber attackers against very complex security frameworks.
These tools make them more intense, efficient and less time consuming than more manual approaches. There are different types of the tools and each has its own level of sophistication. Depending on the kind of DDOS in question, these tools come in pretty handy to speed up the process of the attacks. As system administrators and ethical hackers, it is an added advantage if you are aware of these tools and the way to use them. It gives you an insight into what to take precautions against in your security framework.
These tools are selected as the top 16 based on their functionality and how popular they are among hackers. There are other tools out there that are dangerous and would be effective in carrying out simulations. As cyber-security personnel, it is beneficial that you know as much of these tools as possible to forestall attacks against your framework security.
The Denial of Service attack is a massive attack that is threatening the Internet. Distributed Denial of Service attack is a distributed kind of it and has been known for many years. To defense against the attack, the researchers need to learn the details about the tools used by the attackers. Testing the tools is very expensive in real world but it is possible by experimentation in emulation testbeds. In this paper, we have tested and compared some famous tools, which have been used by attackers nowadays. This test was conducted in the DEfense Technology Experimental Research laboratory testbed with a topology having variety of operating systems and network protocols. As the result of the test, the impact of the contemporary attack tools over the victim machine for the Denial of Service and Distributed Denial of Service attacks is given by graphs where; these graphs are demonstrated for different number of threads caused by different kind of attack tools using percentage link utilization metric. This work presents comparison of different attack tools in DDoS attack and their impact over the websites and link's bandwidth.
There is a tool called HULK (Http Unbearable Load King). It's a web server denial of service tool. It is designed to generate volumes of unique and obfuscated traffic at a webserver, bypassing caching engines and therefore hitting the server's direct resource pool.
