Welcome Back our Tech kiddies. Today, We will explore some popular tools which are used for Network stress testing. As these tools was developed for network testing, but now some people uses these tools for malicious purposes.
Google has released Chrome version 86.0.4240.111 for Windows, Mac, and Linux. This version addresses vulnerabilities that an attacker could exploit to take control of an affected system. The Cybersecurity and Infrastructure Security Agency (CISA) encourages users and administrators to review the Chrome Release and apply the necessary changes. This is where having proper behavioral DDoS detection and prevention software like DataDome can help to recognize malicious activities from legitimate traffic correctly, and effectively filter out the malicious traffic and harmful bot activities.
What is DOS Attack ?
Before proceeding , those who are not aware of the term DOS (Denial of Service Attack), this paragraph is for you :
- DOS (Denial of Service) is an attack performed on computer or network that reduces, restricts or prevents accessibility os system resources to legitimate users.
- In simple terms, Attacker floods the victim system with malicious traffic to overload its resources.
- DOS attack can do temporary or permanent damage to a website. I can also slows down network performance.
DDOS Attack Report
- Largest DDOS attack size is 127 Gigabits per second(Gbps) with speed of 50million packets per second.
- 167% increase in average attack peak size from 2015 to 2016.
Powerfull DoS/DDoS Attack Tools
There are many tools available on internet today. You can also find some tools in Kali Linux. I am figuring out some common and effective tools.
1. Slowloris
Slowloris is the most effective tool for launching the dos attack. It works by opening multiple connections to the targeted web server and keeping them open as long as possible. It does this by continuously sending partial HTTP requests, none of which are ever completed. The attacked servers open more and connections open, waiting for each of the attack requests to be completed.
Due the simple yet elegant nature of this attack, it requires minimal bandwidth to implement and affects the target server’s web server only, with almost no side effects on other services and ports.
You can easily download this tool from github.
2. LOIC (Low Orbit Ion Canon)
The Low Orbit Ion Cannon (LOIC) may be the most popular DoS tool and has made its way into hacker lore. LOIC was initially developed by Praetox Technologies in C#, but was later released into the public domain.
LOIC basically turns computer’s network connection into a firehose of garbage requests, directed towards a target web server. On its own, one computer rarely generates enough TCP, UDP, or HTTP requests at once to overwhelm a web server—garbage requests can easily ignored while legit requests for web pages are responded to as normal.
This tool is available for Linux, Windows and Android as well.
3. GoldenEye
GoldenEye is another popular tool which is used for security testing purposes. This tool is capable of bringing down victims web servers. This tool is written in python. GoldenEye is available on github. You can download it from here.
GoldenEye is an python app for SECURITY TESTING PURPOSES ONLY!

4. HOIC (High Orbit Ion Canon)The High Orbit Ion Cannon (HOIC) is a tool that could aid an unauthenticated, remote attacker in conducting distributed denial of service (DDoS) attacks. High Orbit Ion Canon or HOIC is developed by popular group Anonymous, a hacktivist collective, to replace the Low Orbit Ion Cannon (LOIC) tool. It functions by flooding target systems with junk HTTP GET and POST requests.

The tool can open up to 256 simultaneous attack sessions at once, bringing down a target system by sending a continuous stream of junk traffic until legitimate requests are no longer able to be processed. HOIC’s deceptive and variation techniques make it more difficult for traditional security tools and firewalls to pinpoint and block DDoS attacks.
The HOIC is a popular DDoS attack tool that is free to download and available for Windows, Mac, and Linux platforms.
5. XOIC
XOIC is another nice DOS attacking tool. It performs a DOS attack on any server with an IP address, a user-selected port, and a user-selected protocol. Developers of XOIC claim that XOIC is more powerful than LOIC in many ways. Like LOIC, it comes with an easy-to-use GUI, so a beginner can easily use this tool to perform attacks on other websites or servers.
6. RUDY (R U Dead Yet ?)
R.U.D.Y. is a popular low and slow attack tool that is designed to crash a web server by submitting long form fields.
http://yydnqj.xtgem.com/Blog/__xtblog_entry/19266568-music-converter-pro-mac#xt_blog.
The attack is executed via a DoS tool which browses the target website and detects embedded web forms. Once the forms have been identified, R.U.D.Y. sends a legitimate HTTP POST request with an abnormally long ‘content-length’ header field and then t starts injecting the form with information, one byte-sized packet at a time.7. TOR’s Hammer
ToR’s Hammer was designed to be run through the ToR network to anonymize the attack and limit mitigation. The problem with this strategy is that the ToR network tends to be very slow, thereby limiting the rate at which the packets can be sent and thereby limiting the effectiveness of this tool.

8. THC-SSL-DoS
This DDoS tool (built right into Kali) is different from most DoS tools in that it doesn’t require huge amounts of bandwidth and can be conducted with a single system. It attacks vulnerabilities in SSL to bring down the server. You can download it from THC, but if you are using Kali, you already have it.
9. Pyloris
PyLoris is said to be a testing tool for servers. It can be used to perform DOS attacks on a service. This tool can utilize SOCKS proxies and SSL connections to perform a DOS attack on a server. It can target various protocols, including HTTP, FTP, SMTP, IMAP, and Telnet. The latest version of the tool comes with a simple and easy-to-use GUI. Unlike other traditional DOS attacking tools, this tool directly hits the service.
10. HULK (Http Unbearable Load King)
HULK is another nice DOS attacking tool that generates a unique request for each and every generated request to obfuscated traffic at a web server. This tool uses many other techniques to avoid attack detection via known patterns.
Dos/DDos Attack Tools For Android
1. AnDOSid
AnDOSid is an android tool developed by Scott Herbert that you can use to launch DoS attacks from your mobile phone. It was developed as a stress testing tool, but you know, anything can be misused, even a pen….
AnDOSid is so powerful, that you can even use it to take down web servers.
2. LOIC
Low Orbit Ion Cannon is a simple application that allows users to send UDP, HTTP, or TCP data packets to any IP address. LOIC can help users with testing server data flow by emulating controlled traffic flow. Since LOIC supports all three socket protocols (UDP, TCP, and HTTP), LOIC could thus be used with any type of server.

DDos is defined as “Distributed Denail of Service Attack“. This tutorial explains what is DDosing and how to hack a website temporarily using DDos method.
It is a very common news when you hear that a website is hacked by a group or a website is crashed and etc. etc. Have you ever wonder how a hacker group take a website down or do you know the exact method of crashing a website? Actually there are several methods which are used by the hacker group. However, using Distributed Denail of Service Attack technology, any small website can be crashed very easily.
DDos – Distributed Denail of Service Attack
Every web server has it’s own capacity of handling requests at a particular time. A DDos can be occured when a web server or a system gets so many requests at one time which it can’t handle, then the system hangs or shuts down automatically. This results in a website is crashed or temporary down. When a website becomes a victim of DDos attack, it looses all it’s allotted bandwidth which makes the website server temporary down. Overloading a network or flooding a web server by sending huge amount of requests at a time results disconnection of data transmission between a server and a user. Thus a website goes to temporary down state or faces server unavailable problem due to DDos a website. Until the system administrator analyses all the requests, it is impossible to filter attackers’ request.
There are several ways to DDos a website. I mention here command line manually DDos and automatically DDos using free tool techniques.
Method #1: How to DDos a Website Manually Using Windows Command Prompt
- Select a small website that you want to DDos attack.
- Find the IP address of the website. To find the IP address of a specific website just use the following command:
The IP address looks similar to xxx.xxx.xxx.xxx
- Now type the following command:
- Run the command for hours. If possible use multiple computers to run the same command at a same time.
- Now, when you visit the website after 2 or 3 hours, you will find the “website is temporary down” or “server unavailable” message.
Note: You should have a internet connection with unlimited bandwidth. Otherwise you lose all your internet bandwidth for performing the task.
Method #2: Website DDos Attack with LOIC Automatically
To lag down a website or to completely shut down a website you need a tool, named LOIC (Low Orbit Ion Canon). Lets see how to DDos a website using Low Orbit Ion Cannon.
- Download the software from the below link:
- Once, you download the software, extract the software to Windows desktop.
- Targeting the website: Double click the software icon to open it. LOIC is a portable software and requires no installation.
- Now, put the website address that you target in the ‘target URL’ field.
- It is optional to put the IP of the targeted website in the IP field. You can get the website IP by using ping command from your Windows.
- Press the ‘lock on’ button which is next to the text field.
- Under ‘Attack’, don’t change timeout, HTTP subsite, speed bar.
- Under ‘TCP/UDP Message’, enter whatever you want to right.
- Under the ‘Port’ field, change the value of the port of the targeted website. In most of the cases the value ’80’ should work.
- Under ‘Method’, from the drop-down list, select UDP option.
- Uncheck the ‘Wait for reply’ check box.
- Change the thread value to 20 if you have a good computer. Otherwise, keep the value to 10.
- Press the “IIMA CHARGIN MAH LAZER” button.
Run the software at least for an hour. Then, visit the website you target and you should see the “Service Unavailable” problem there. This is the way how you DDos a website and makes it down temporarily.
Method #3: How to Use Google Spreadsheet to DDos a Website
Ddos Software Mac
Google always use a feedfetcher crawler to capture the image, then display the cache image. Google use the same technique using Google Spreadsheet to cache and display any image that is inside =image(“”) value. For example, if i put =image(“https://www.techperiod.com/wp-content/uploads/2016/01/LOIC.png”) function in the spreadsheet, it fetches the image and display it.
Using a random parameter request, one can ask feedfetcher crawler to crawl exactly the same file multiple times. If I use a large pdf file link, Google feedfetcher crawler will fetch nothing. But, it crawls the website multiple times and results a lots of outgoing bandwidth/traffic loss. As, it fetches nothing, so there is no fear to loss your bandwidth.

In this case the spreadsheet function should be something like this:
Games you can play on a macbook. So, using a single laptop, anyone can disaster a website and sends 250GB traffic within 45 minutes.
