Distributed Denial-of-Service (DDoS) attack is a subdivision of Denial-of-Service (DoS) attack that overwhelms the targeted network, website, and server with bogus traffic to disrupt normal traffic. Attacks are usually random and the online DDoS attack tool automatically chooses the target, but the online DDoS attack can also specifically target a particular network, website, and server. All the information provided in this blog is purely educational, we do not support any kind of illegal malware activity online. DDoS attacks are illegal in most countries around the world and the person can be imprisoned for up to 10 years if convicted in the US.
Best Free Online DDoS Attack Tool
The DDoS attack can be used for good and bad things. Mostly hackers use it for notoriety purpose to disrupt victim’s servers or services. There are many tools available to carry out a DDoS attack online.
Listed below are the best free DDoS tools available for download with their features.
1. HULK (HTTP Unbearable Load King)
This tool sends dark and unique traffic to a web server. It is a denial of service attack tool, but the traffic it sends can be blocked and the attacker may not be completely anonymous. states that it was created for research purposes only, although it may be used for more than research purposes.
Characteristic:
- A large volume of unique traffic is generated towards the destination web server.
-
Harder to spot but not impossible.
- It directly accesses the resource pool of the servers without going through the caching engine.
2. Hammer of Tor
It is best used with the Tor network to remain unidentified while performing a DDoS attack. To use it with the Tor network, use this 127.0.0.1:9050. it is created for testing purposes but can be used for a slow post attack. Using Tor’s Hammer, the user can attack IIS and Apache servers.
Characteristic:
- Specialized for anonymous attacks.
- It is also used to carry out demo attacks by penetration testers on security frameworks.
- It operates at level 7 of the OSI model.
3. Lentoris
is a layered application that attacks threaded servers by using partial HTTP requests to open connections between the target web server and a single computer, then the connections are kept open for longer periods to fill up and slow down the target servers with traffic.
Characteristic:
- It carries out attacks by sending legitimate HTTP requests.
- You can maintain the connection to the victim’s server for as long as necessary.
- Requires minimal bandwidth on the destination web server.
4. LOIC (Low Orbital Ion Cannon)
is a popular tool and one of the best DDoS attack tools online. The interface is very easy to use and the LOIC sends HTTP, UDP and TCP requests to the servers. It is effective within seconds, the targeted website will be down seconds after the attack started, but it does not hide your IP address even after using the proxy server.
Characteristic:
- It is mainly used to attack small servers.
- Available on Linux, Windows and Android.
- Easy to use, few steps to start an attack.
5. RUDY (UK-Dead-Still)
It scans the target DDoS site automatically and finds the embedded web forms. It only executes short, slow-speed Layer 7 DDoS attacks that are implemented by using long-format field sends that generate slow, low-rate traffic.
Characteristic:
- Hard to spot.
-
Interactive console menu.
- It works at a slow pace.
6. Pyloris
is a tool to test the vulnerability of a server to connection exhaustion using the total number of simultaneous TCP connections if there is a restriction on it. Services that have a high memory footprint per connection or that handle the connection in separate threads are mostly prone to this form of vulnerability.
Characteristic:
- Attacks can be carried out over SMTP, HTTP, FTP, Telnet, and IMAP.
- Interactive and easy to use interface after installation.
- It uses SOCK proxies and SSL connections.
7. DDOSIM (Distributed Denial of Service Simulator)
is to simulate the DDoS attack on the website and on the network. It attacks the server by replicating multiple Zombie hosts and then these hosts develop a full TCP connection to the server or network.
Characteristic:
-
HTTP DDoS attacks can be made using valid requests.
- DDoS attacks can be carried out using invalid requests.
- It works on Linux and Windows.
8. Davoset
It is used to carry out attacks on websites by gaining access through other sites. This particular method is recently being used by hackers for malicious activities on the web. This tool helps you to perform DDoS attacks with ease.
Characteristic:
- Provides support for cookies.
- Free software that provides a command line user interface to commit an attack.
- Performs an attack using XML external entities.
9. Golden Eye
The tool performs an attack by sending an HTTP request to the target server. It uses all the HTTP/S sockets present on the target server for the DDoS attack.
Characteristic:
- Randomize GET, POST to get the mixed traffic.
- Written in Python.
- Easy to use.
10. OWASP HTTP POST
helps you test the network performance of your web applications. It allows you to write a denial of service from a single online DDoS machine.
Characteristic:
- Users can choose the capacity of the server.
- Free to use even for commercial purposes.
- Allows the user to test against application layer attacks.
11.XOIC
is a tool that performs an attack on smaller websites by using TCP, UDP messages. Attacks carried out by Xoic can be easily detected and blocked.
Characteristic:
- It comes with three attack modes.
- Very easy to use.
- Perform DoS attacks with ICMP, UDP, HTTP, or TCP messages.
12. HOIC (High Orbital Ion Cannon)
is a tool that was released to replace LOIC. You can perform 256 concurrent attack sessions at once. Filling the target system with unwanted requests so that the legitimate request cannot be processed.
Characteristic:
- Totally free to use.
- Available for Windows, Mac and Linux.
- Allow users to control attacks with low, medium, and high settings.
13. hyenas
allows you to produce multiple MITM, DoS, and DDoS attacks that come with a poolable remote daemon and interactive attack wizard.
Characteristic:
- Tons of features like ARP-Request Flood, ARP-Cache Poisoning, ICMP-Echo Flood, etc.
- Intelligent detection of addresses and address protocols.
- Smart wildcard based randomization.
14.THC-SSL-DOS
is a tool that helps the user to carry out an attack on the target website successfully by exhausting all SSL connections and shutting down the victim’s server.
Characteristic:
- Users can verify the performance of SSL.
- It also takes advantage of SSL’s secure renegotiation feature.
- Compatible with Linux, Windows and macOS.
15. Apache Reference Tool
It is basically used to load test a servers by sending numerous simultaneous requests. Other than this, it can also be used to carry out a DDoS attack.
Characteristic:
- You can compare any HTTP server.
- Show the result at the end.
- Compatible with Windows and macOS.
