In this documentation we will cover almost every aspect of the CryptoStresser platform including its history and how to use it effectively. As well as other things related to general DDoS attacks and protection systems.

CryptoStresser History

We launched our first DDoS attack platform a few years ago around 2018 which was soon re branded as SynStresser. It was the most advanced DDoS service ever offered to customers via a web platform. It had the latest technology for DDoS attacks and a slick, easy to use, modern design with no customer interaction required, high power and frequent updates. After a year of operation SynStresser was re-branded as StresserNET which featured a new web platform, with a more modern and intuitive design focused on ease of use, a faster and smarter attack system which used network rotation and load balanncing to be able to handle more users without any power loss. It was a success and it was the biggest DDoS service of 2019 and 2020 with hundreds of thousands of registered users and over 10 million attacks sent. It was revolutionary. Unfortunately our team needed to take a break so we redirected all our users to a competitor service where they got to continue having a similar experience and service. But on mid 2021 we realized it was time to come back. The service provided by said platform and said competitor was below our standards and we knew we could do better, so we set to code the most efficient and powerful DDoS system ever created for our users, and thats how CryptoStresser was born.

Our Technology

As simple as our platform may seem, the technology and infrastructure we use to support it is truly impressive. Everything is coded from scratch for high performance and security using over 5 programming languages. We can not disclose everything thats behind our impressive attack system, but we have over 60 servers which amount to over 7.5TB of RAM and 1500 CPU cores and a huge upstream network capacity.
Most of our "competitors" are using public code which is outdated by several years, its not secure, comprimises user privacy, and gives a terrible user experience, it may "look" fine for the first day, but when you have to use the platform repeatedly, their issues, slow loading speed, downtime and bugs will be a headache.
We pride ourselves in doing honest marketing, without giving fake statistics or numbers, those stressers claiming to provide 1000 Gbps are mostly lying. Unfortunately the widely available public DDoS attack has enabled people without much knowledge to create seemingly good DDoS services but in reality they are mostly useless and they rely on false claims and scamming users, since their service doesnt or barely works.

Our Rules

We do not take responsability by any unauthorized DDoS attack.

We dont allow attacks on several government, financial, health and other sectors by default. Ask us if your target is blocked.
Harming the platform in any way or its staff is, of course, forbidden.
Any action can be applied to users based on our judgement.
Common sense and community rules. We are lucky to be able this service mentality.

Getting Started

What is a DDoS attack?

In simple terms, a DDoS attack (distrbuted denial of service) consists on overloading an internet service by sending more traffic that it can handle. In the case of a website (Layer 7 attack) you can imagine it as thousands of users visiting the website at the same time until it collapses. In the case of a game server, residential wifi, or network (Layer 4 attack) you can imagine it as hundreds of Megabytes being downloaded until it can no longer process and legitimate traffic.

What is a DDOS Stresser or Booter?

Stresser is a name used for platforms like CryptoStresser which provides users the ability to test (stress test) their website or network against a real DDoS attack to see if it goes offline or it holds up.

Does size matter?

People like to classify DDoS attacks by their size in terms of total traffic being sent per second, such as how many dozens or hundreds of Gigabytes per second, or fake visitors sent to a website.
At CryptoStresser we believe SIZE DOESNT MATTER. In the modern days DDoS protections are very advanced and able to detect and block big DDoS attacks easily. So we take a smarter approach. Our attack methods are developed to be undetected by firewalls (bypass) and avoid getting blocked. We can get better results sending 1 Gbps (gigabyte per second) than one hundred.
Many competitor platforms still try to lure users by advertising the amount of fake data their attacks send, and showing pictures of graphic metrics. In many cases they cant even send this much data, and even when they can, its mostly useless in 2022.

What DDoS protections can we bypass?

Every website and network is different, they are built with different technology and have different network capacity. We are proud to say we can take down the majority of internet services offline, including famous and popular websites. That being said, DDoS attacks are not a permanent solution to disable a website or target, and eventually, depending on their IT skills, budget and time spent they will be able to block the attack. But likely will suffer a big loss to achieve that, in terms of money, user experience, SEO, etc.

Can I be tracked through DDoS attacks?

Many people wonder if the attacks can be traced back to them. The answer is no, attacks sent through our service can not be traced back to you in any way. Unlike attacks sent using other tools / services like LOIC / HOIC etc which send from your computer using your IP address and network, CryptoStresser DDoS attacks are carried by a decemtralized network of computers and servers around the world. You are never in direct contact with the attack, you just manage it using our platform.

Using our Platform

Important: Hopefully after reading this guide you will be able to make effective use of our platform to achieve our goal without needing to contact us.

Choosing a membership

Important: This is a crucial step to your success.

First, lets define the components of a CryptoStresser membership.

Max Attack Time: this refers to the maximum time each one of your attacks can run for before ending. This is not a limitation on the number of total attacks you can send over the duration of your membership, which is unlimited.
For example if the maximum attack time is 1200 seconds, each attack you send can run for 20 minutes before ending.

Max Simultaneous Attacks: this is the most important component of a membership, since it defines the number of attacks you can have running at the same time.
Each attack has a fixed amount of power, thus the more attacks you send on a target, the stronger and more effective the attack will be.
Also it allows you to attack multiple targets at the same time.

How many simultaneous attacks will you need depends on your target resilience to DDoS attacks, or the amount of targets you want to attack at the same time.
If your target is used to experiencing DDoS attacks or it would lose money by being offline it probably has DDoS protection, so you will need several simultaneous attacks.
As much as we wish every target would go down with 1 or 2 attacks, some targets, like big game servers, gambling, streaming, financial or news websites may require, 10, 20 or more attacks.

In case the amount of attacks you have is no longer enough for your needs you can always upgrade to a bigger membership and receive a discount for your previous purchase, by using the discount code UPGRADE on checkout.

If you cant accurately estimate the amount of attacks you need you can always contact us for a test and a quote, we will reply as soon as possible.

The Dashboard

CryptoStresser dashboard page has 2 main elements, statistics about our platform and more importantly the list of all the news and updates we do to our service, its important to stay up to date to know the current operational status, and be informed on the latest technologies added to our platform.

Memberships Page

This page has 3 sections, on the top left, a customizable premium membership. Customizable means you can make any combination of simultaneous attacks, attack time and membership duration that fits your needs. Unlike fixed memberships you can choose an attack time higher than 10800 seconds, and any number of simulaneous attacks, as well as up to 3 months duration.

The second section contains frequently asked questions about memberships, how to pay, how to upgrade, etc.

The third section contains all the pre made fixed memberships which offer a cheaper price compared to custom memberships.

Your Settings

The settings page shows statistics about your current account and your current membership, it allows you to change your password, add your telegram ID, see your daily attack logs, invoice logs, API key and API documentation, as well as delete any of those logs at any time, and optionaly delete your account.


In here you can find us showing some of the websites and targets that have been successfully attacked by our service. You can find a lot more in our Telegram channel. All the targets here are just for demostration purposes and have been blacklisted from our attack system.

Network Status

This a very useful page. CryptoStresser attack system is shared by all our customers, so in rare ocassions all the attack spaces might be full for a specific attack method, Network Status shows how many available spaces there is on each attack network.

Currently we have over 800 total attack spaces, and the regular usage is up to 300/800, we always add more attack space when necessary.

Frequent Questions

This page contains generic information about our website, service and attack methods, all the information should also be found here, but we ll keep the page just in case.

Attack Panel

The most important part of CryptoStresser is the Attack Panel page (and the API). Lets take a look at it.

On the right side we have a small box with your membership information and a link to this documentation.

On the bottom we have a box with your running attacks, or attack history. In this table you will manage all your attacks and be able to stop and view information.

running attacks

In here you can stop each attack individually, you can stop all your running attacks, the selected attacks, or the last 1/5/10 attacks together. Once you press the button the attack will be instantly stopped and has to be relaunched manually.

attack builder

The image above is CryptoStresser's DDoS attack builder.

  • Attack Target: the target you want to send the attack to, if its a website use the full URL including http(s)://. See more information about choosing your target on the next section.

  • Attack Duration: this is self explanatory, how long this attack will run in seconds, you can manually stop it before the time ends.

  • Attack Duration: attack port, this only applies to IP address targets, for example game ports or TCP applications run on a specific port, its specially important in TCP attacks to attack open ports, for UDP port 0 is recommended.

  • The fields below are OPTIONAL dont use them if you dont know what you are doing, ask for our help.

  • Request Method: the request type to use in the attack, POST or GET, find more information at

  • Post Data: what post data should the attack requests carry, it can be url encoded or JSON format using "" and {} with no spaces.

  • Ratelimit Bypass: a common DDoS protection called ratelimit limits the amount of requests an IP address can make in a specific time frame, without this settings most attack methods do 4 requests per second per IP, with this setting they do 2.

  • User Agent: which type of device should perform the attack, phones, computers, tablets or bots? or a custom user agent if you want. Default recommended unless necessary.

  • Cookies: cookies to use in the attack, can be logging or user sessions after login if static, combined with post data sometimes.

  • Referrer: Default is empty, usually the best, unless you know what this is.

  • Attack Origin: If you want to take down a geo-blocked target better buy many attacks attacks and send them together world wide.

Attacking Your Target

Planning your attack

Once you start attacking your target they will most likely begin their efforts to mitigate and stop the attack, is not possible to estimate how long it will take them, so its important to plan your attacks well. Think strategically and only attack when its most important to you. You can do it at night when they are sleeping, or busy.


If your target is a website, you most likely want a Layer 7 attack. If its an IP address then probably you need a Layer 4 attack.

As previously explained, your membership matters a lot, specially the amount of simultaneous attacks you can have.
Each attack you send will have a determined maximum power, lets say 10. So if you send 2 attacks to your target, the power sent is 20. If you send 10, then 100.
Another important reason to have multiple attacks is the ability to combine attack methods. Sending multiple attacks with different protocols can be effective to bypass protections and overload the target.

Purchasing a membership is an automated process, just select the one you want, proceed to checkout, paid the specified amount of the choosen cryptocurrency, and the membership will be enabled automatically shortly after, you can close the page at any time.

Upgrading your membership is also an automated process and requires no human interaction, you can always ask for help at any time, we are fair.

Tips to DDoS (stress test) websites

Its highly recommended that for Layer 7 attacks you always choose an URL target that consumes a lot of resources on the target server, like a login, search, register, submit data operation, captcha generation, etc.

If you attack on a page that is mostly cached by a CDN or even the target server it may have no effect at all.

USe a combination of dynamic page targets, cookies, post data, or what ever needed.

All our attack methods allow for dynamic text randomization using %RAND% and %RANDINT%.
%RAND% will be replaced with alphabetic strings 4-8 characters long.
%RANDINT% will be replaced with numeric strings 4-8 characters long.

This is useful to generate dynamic data in the attack, for example search queries, usernames or passwords.
For example an attack on may be harder to block than attacking

You can also specify the amount of dynamic characters generated, for example.
%RAND% = 4 to 8 random letters.
%RANDINT% = 4 to 8 random numbers.
%RAND9% = 9 random letters.
%RANDINT16% = 16 random numbers.

The maximum is a combined 999 randomized characters between all the usages of this feature in a specific attack.

This can be used in attack target, post data, cookies and referrer.

Use with caution dear users!

The technical aspect (DDoS is not magic)

CryptoStresser may seem like a magic tool sometimes, it may also seem completely useless, in reality, its up to the way you use it. If a few seconds after starting the attack your target is completely offline you will be very happy, but if it doesnt, you will think our service doesnt work. Thats why its important to understand what goes on under the hood, the technical aspects of our DDoS attacks, to give you the best chances of success.

What I mean is, our service always works as intended, but all targets are different and may require some additional effort to find the right attack configuration. For some targets it may be as simple as pasting the URL and pressing the button but in most cases thats not the best approach, even if it works.

If you are not an expert this may seem complicated (and it is) thats why you can contact us for custom help on your target. We made our tool and service as easy to use as possible, but if you want to get the best performance you need to do some advanced usage.

It all boils down to how a DDoS attack works. The goal is to overload and exhaust the target resources, making it unable to perform its intended tasks.
In the case of a website, there is many different services and processes required to make the website work, so we need to find the weakest service and crash it.

For example an average website runs on a server, which has a fixed number of bandwidth, CPU and RAM. The server is running several programs to serve the website, such as a web server and database. If we manage to exhaust its resources or crash one of these programs, the website will be temporarily unavailable, its that simple.

It is hard to explain how to effectively make use of this information, but lets look at a basic example.
If you attack a website at "" the attack will go to "/" (the landing page) which usually consists of static resources (text, images, etc). Serving this content to users costs very little resources from the server, as its usually cached, and its a small file, so very low bandwidth, cpu and ram usage. If the website is properly configured this attack has a very low chance of success even with a very big attack.

But on the other hand if you attack the same website at a search form like /search?q=%RAND% or a .php page, you force the server to run database queries, or at least some code in the server, causing more resource usage and problems on the target.

CryptoStresser Attack Methods Explained

Layer 7 methods - website

  • [FREE] HTTP\/S (SPAMMER) - A less powerful version of SPAMMER v2

  • [FREE] HTTPS (FURY) - A less powerful version of HTTPS-STRONG

  • [ENTERPRISE] SPAMMER v2 (HTTPS/1.1) - Send thousands of requests per second with valid headers to a website from an pool of over 10,000 unique users worldwide. Good for websites without mitigation, ratelimit or protection. Socket like method. Works on http/s websites.

  • [ENTERPRISE] SOCKET V4 (HTTP\/1.1) - Opens thousands of TCP/IP connections with the target and transfer multiple HTTP headers to produce thousands of unique visitors. Works best on http:// targets with low to no protection.

  • [ENTERPRISE] HTTPS-STRONG (HTTPS\/1.3) - Sends around 10,000 fully valid SSL requests to your target website, good for most websites that use https:// and some kind of protected CDNs.

  • [ENTERPRISE] HTTPS-CRYPTO (HTTPS\/2.0) - Similar to https-strong, recommended against cloudflare or in combination with https-strong. Sends thousands of http 2.0 SSL requests, recommended for popular CDNs or wesites that accept http/2 requests. Some dont.

  • [ENTERPRISE] HTTPS-RAND (HTTPS\/1.3) - Same as https-strong but random request protocols, GET / POST / HEAD among others, I have personally crashed a strong NGINX https:// server, permanently, that i was using for tests. Not recommended for targets with DDoS protection or Cloudflare as it can be easily blocked.

  • [ENTERPRISE] PRIVATE / BOTNET (HTTPS\/2.0) - This methods mimic the most valid requests possible and send hundreds of thousands of HTTPS TLS requests to target, can crash many big websites even using CF and other CDNs. Only http/2.0 sites.

  • [ENTERPRISE] BROWSER (JSBYPASS v7) - This method can bypass Cloudflare UAM (JS challenge) and automatic captcha. As well as many other basic JS challenges and cookie based protectons. It takes up to 120s for the protection to be bypassed before the attack starts. Please ONLY use this method on targets that have one of these challenges, otherwise it wont work.

Layer 4 methods - IPv4

As explained in Does Size Matter section, the total traffic of a DDoS attack has little to no importance in the modern day, instead choosing the right method for your target is what makes the difference. There is a missconceptions that the more Gigabits per second your attack sends, the better. How ever against most targets today this is not the case. Modern protections can easily block big attacks since they are easier to detect and mitigate. Although it may be easier or preferred to just send a huge attack and completely offline your target, its hard to do and not practical. The chances of success are much higher if you put some effort to find the right TCP or UDP port used by the application you want to attack and then choosing the correct DDoS method. Thats why we bother to give you all the details about the methods we offer so you can make an informed, efficient choice.

As an example of what we stated above, some of the largest attacks in history were carried using common UDP amplifications (which we also offer) like NTP, SSDP and others. But did you know these attacks come from a single source port (123 and 1900) which can be easily blocked to stop attacks even if they are thousands of Gbps in size. Relying in high amounts of traffic to be effective is not only expensive but stupid.

TCP Bypass methods: All the methods in this category use the same protocol (TCP) and are ment to be used againt servers running application on said protocol. The port you attack should be open and used by the application you want to crash. They may not be able to take the server fully offline but they can crash the specific open port or application your targetted even on a big or protected server. Common examples of TCP applications are Webservers, SSH, MYSQL and some games. Unlike in UDP attacks which are a more brute way of attacking, these methods target an specific port to have higher effectivity even on protected services.

UDP Bypass methods: They are also ment to be used on the correct UDP port used by the application you want to target. Most games run over UDP so if you can find the game port it may be the right move to use one of these methods. They usually send smaller amounts of traffic and may not be able to fully offline the server but may create enough latency to disrupt the game or the service using the open UDP port.

TCP / UDP Direct methods: These methods are similar to the Bypass ones but arent aimed to bypassing DDoS protections and rather send more direct floods with higher traffic amounts. Can be effective in some cases and can be tried as last resource.

UDP Amplification methods: The methods in this list are unique because they abuse different protocols to force thousands of internet devices into sending a DDoS attack to your target similar to like a Botnet would. You dont need to understand how they work, but for example in a DNS attack, the attacker will make thousands of queries to servers around the world and they will send large responses via UDP to your target which will be saturated due to the incoming traffic. These methods are usually very publicly known and most DDoS protection providers and ISPs block them by default. They can still be effective and worth a try specially against residential connections, low bandwidth servers and unprotected machines.

DDoS Botnet methods: In this category you will find some of the strongest Layer 4 methods available in CryptoStresser which come from thousands of devices around the world connected to our botnets and each attack can send 3-10 Gbits of TCP with 1-3M pps and 5-20 Gbps UDP.

BOTNET-TCP (SYN, ACK, MIX): These methods send high size TCP packets over different protocols from thousands of devices around the world (usually in US and CN) and are hard to block by most DDoS protections. Its recommended to use them in combination with other methods to create a stronger attack. This method doesnt target a specific port like most TCP methods do.

TCP-REFLECT: This is a unique method which reflects TCP packets from real IPs back to your target IP, being able to send attacks from mainstream network providers such as Google, Amazon, Cloudflare as well as countries such as China, Korea, US, Japan and many others. This method generates high incoming ans outgoing traffic on a target as well as sending millions of packets per second and can bypass many protections. This method targets ports 22 443 3306 and others.

ABUSE-REPORT: This is NOT a DDoS attack method. When you launch an attack usint this method the target wont go offline directly, instead it will use the target IP to perform illegal actions like port scanning against other hosts which will in turn send abuse reports back to your target IP. So your target IP may be permanently suspended by their hosting provider once they receive enough reports as this usage is against their TOS and AUP. Its recommended to run this method for a few hours and the effectivity will vary a lot from target to target depending on their hosting provider and tolerance to abuse.

FREE DDOS Methods In CryptoStresser

Yes! you can find several Free DDoS attack methods in CryptoStresser. Both for Layer 4 (IPs) and Layer 7 (Websites).

These methods have very low power compared to any paid attack, and your options are limited to only a handful of protocols.

The free options are only ment to show how the attack system works, how fast it is and that our attacks are actually working and can send traffic. How ever with you may be able to take down small to medium websites or servers if they have no good DDoS protection.

While all our Free IP Stresser methods work, we provide no guarantees on them or what they may be able to do. Please do not contact Support staff regarding the free methods and their effectivity. We can ALWAYS GIVE A FREE TEST on your target using paid methods. Just contact our support via live chat and telegram send the target and wait.

The free methods are usually a weaker copy of our paid methods and the name should reflect that.

FREE HTTP SPAM is a weaker version of SPAMMER V2, while FREE HTTPS FURY is an older version of HTTPS STRONG. The same applies for Layer 4.
