The rise of Denial-of-Service (DoS) attacks has made it crucial for cybersecurity experts and ethical hackers to understand the tools that are used to execute them. Impulse is a modern DoS toolkit designed to perform various types of network attacks with ease. It offers a variety of methods such as SMS floods, email floods, and amplification attacks, making it a versatile tool for penetration testers and security enthusiasts.
Impulse provides an efficient way to simulate real-world DoS attacks, allowing ethical hackers to assess and improve the security of targeted systems.
Why Denial-of-Service Attacks Matter
Denial-of-Service (DoS) attacks are among the most common and disruptive forms of cyberattacks. These attacks work by overwhelming a target, making it impossible for legitimate users to access services. Whether it’s flooding a website with HTTP requests or bombarding a phone with SMS messages, the goal is to make the target system unresponsive.
Impulse's Role in Cybersecurity
Impulse is more than just a tool for performing DoS attacks—it's a vital resource for testing the robustness of networks and servers. By using Impulse in controlled environments, ethical hackers can identify vulnerabilities and help secure systems before real attackers

Attack Methods Supported by Impulse
Impulse supports a wide range of attack methods, each targeting different vulnerabilities to overwhelm a system. Below are the key methods you can use with this toolkit, each tailored for specific use cases and attack surfaces.
SMS Flood
The SMS flood method targets phone numbers by sending a massive volume of SMS messages in a short amount of time. This overloads the recipient's phone and disrupts their ability to use it effectively.
Email Flood
The email flood method targets email addresses by sending an overwhelming number of emails. This can cause the target's inbox to overflow, potentially disrupting their communications and productivity.
NTP Amplification
NTP amplification attacks target publically accessible Network Time Protocol (NTP) servers. By exploiting these servers, the attacker sends a large volume of UDP traffic to the target, overwhelming their network.
SYN Flood
The SYN flood (also known as a half-open attack) sends numerous SYN requests to a server without completing the handshake process. This consumes server resources, preventing legitimate traffic from being processed.
UDP Flood
In a UDP flood attack, numerous User Datagram Protocol (UDP) packets are sent to a target IP and port. This can exhaust the server's resources, causing it to become unavailable to legitimate users.
Always use these attacks for legal penetration testing. Misuse can result in serious legal consequences.
Ping of Death (PoD)
The Ping of Death attack sends oversized or malformed packets to a target using the simple ping command. This can destabilize or crash the target system.
ICMP Flood (Ping Flood)
An ICMP flood overwhelms the target with echo requests (pings). The sheer volume of these requests can bring down a system by consuming its bandwidth and processing resources.
HTTP Flood
HTTP flood attacks overload a web server by sending numerous HTTP requests. This can slow down or crash websites and web applications, disrupting access for legitimate users.
Slowloris Attack
The Slowloris attack method maintains a large number of open HTTP lahconnections with the target. This slowly consumes the server's resources, making it unable to handle other requests.
Memcached DDoS
A Memcached DDoS attack spoofs requests to vulnerable UDP memcached servers, which flood the target with internet traffic. This overwhelms the target's resources, causing a denial-of-service.

Example: SMS and Call Flood Attack
One of the most common uses of Impulse is to perform an SMS and Call flood attack. This method targets a phone number and overwhelms it with a high volume of SMS messages and phone calls within a short timeframe. Below is an example of how you can execute this attack using the Impulse toolkit.
SMS Flood Command
To initiate an SMS flood, you'll need to specify several parameters, such as the method, time, threads, and the target phone number. Here's an example command:
python3 impulse.py --method SMS --time 20 --threads 15 --target +380123456789
This command sends a flood of SMS messages to the specified phone number (+380123456789) for a duration of 20 seconds using 15 threads. This results in a massive volume of messages being sent in a short time, overwhelming the target's phone system.
Call Flood Command
Impulse can also initiate a call flood attack. The command is similar to the SMS flood, but you would specify the call method:
python3 impulse.py --method CALL --time 20 --threads 15 --target +380123456789
This command floods the target's phone with calls for 20 seconds, making it difficult for them to use their device effectively.
This is for educational purposes only. Do not perform such attacks on individuals without their explicit permission or in unauthorized environments.
Explaining Parameters
- --method: Specifies the type of attack (SMS or CALL).
- --time: Duration of the attack in seconds.
- --threads: Number of threads to use for the attack (higher threads increase intensity).
- --target: The target phone number you want to flood.
Ensure you have the target's consent when performing any testing, as unauthorized actions are illegal and can have severe consequences.
