Simple SYN Flooder and Spoofer
This was created for educational purposes to demonstrate how SYN attacks work. It can also be used to test the effectiveness of firewalls claiming to block SYN flooding.
Multiprocessing version
uses multiprocessing, meaning it will create N workers which will run their own spoofer and SYN flooding. Specify
--workers=N to control how many processes you want to spawn.
The spoof addresses are hardcoded and will use following format 10.10.n where n is a process number. For example, if you spawn 4 workers, the spoof address per worker becomes:
10.10.1.x
10.10.2.x
10.10.3.x
10.10.4.x
Install
Tested and developed with Python3.6.
pip install -r requirements.txt
