DoSinator: Powerful Dos testing tool

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


  • Multiple Attack Modes: DoSinator supports SYN Flood, UDP Flood, ICMP Flood,Os Fingerprint, Slowloris, and Smurf attack modes, allowing you to simulate various types of DoS attacks.
  • Customizable Parameters: Adjust the 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 the 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.


  • Python 3.x
  • scapy
  • argparse
