It uses a list of NTP servers to flood a specified target with NTP response packets. This can be used for educational purposes to understand the mechanics of NTP amplification attacks.\n\n\u003e **Warning:** This script should only be used in a controlled environment with explicit permission from the target. Unauthorized use of this script can lead to legal consequences.\n\n## What is an NTP DoS Attack?\n- An NTP DoS attack floods a target with traffic by tricking time servers into sending massive responses to the victim, causing slowdowns or crashes.\n  \n## Requirements\n\n- Python 3.x\n- Scapy library\n\nYou can install Scapy using pip:\n\n```bash\npip install scapy\n```\n\n## Usage\n\nTo run the script, execute the following command in your terminal:\n\n```bash\n./ntp_ddos.py \u003ctarget_ip\u003e \u003cntp_server_list\u003e \u003cnumber_of_threads\u003e\n```\n\n## Parameters\n\n- \u003ctarget_ip\u003e: The IP address of the target you want to flood.\n- \u003cntp_server_list\u003e: A text file containing a list of NTP server IP addresses (one per line).\n- \u003cnumber_of_threads\u003e: The number of threads to use for the attack. Ensure this is less than or equal to the number of servers in your list.\n\n## Notes\n\n- The NTP server list file should contain one IP address per line.\n- Make sure your thread count is less than or equal to your number of servers to avoid the script terminating prematurely.\n\n## How It Works\n\n- The script reads the target IP, NTP server list, and the number of threads from the command line arguments.\n- It creates a UDP packet directed at the NTP server with a random source port.\n- Multiple threads are spawned to continuously send these packets, amplifying the flood towards the target.\n\n## Stopping the Attack\n\n- To stop the attack, you can use CTRL+C in the terminal. This will safely exit the script and stop the packet sending.\n\n## Disclaimer\n\n- This script is for educational and research purposes only. Ensure you have permission to test against the target IP address. Misuse of this tool may violate local laws and regulations.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffalkern%2Fntp-dos-attack","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffalkern%2Fntp-dos-attack","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffalkern%2Fntp-dos-attack/lists"}
