DoSinator is a powerful Denial of Service (DoS) testing tool developed in Python. Designed for security professionals and researchers, this tool allows them to simulate various DoS attacks, providing a realistic environment for assessing the resilience of networks, systems, and applications against potential cyber threats.


  • Multiple Attack Modes: DoSinator supports various attack modes, including SYN Flood, UDP Flood, ICMP Flood, OS Fingerprinting, Slowloris, Rudy, SCTP, Smurf, and ARP attack modes, allowing you to simulate different types of DoS attacks.
  • Customizable Parameters: Adjust packet size, attack rate, and duration to fine-tune the intensity and duration of the attack.
  • IP Spoofing: Enable IP spoofing to mask the source IP address and enhance anonymity during the attack.
  • Multithreaded Packet Sending: Utilize multiple threads for simultaneous packet sending, maximizing attack speed and efficiency.
  • Data from File: Load custom data from a file to be sent in the attack packets.
  • PCAP Output: Save the outgoing attack packets to a PCAP file for further analysis.
  • ARP Flooding: Perform ARP flooding attacks to disrupt network communication.


  • Python 3.x
  • scapy
  • argparse
