Just coded this, it's in perl so you need perl to be able to run it
It's flooding an ip on a specific port. You can choose the port, the size of each packet and the timeout.
I added a feature that allows you to flood random ports with random packets, and to keep flooding until you break it.
Enjoy!
VT (8/60) :
The positive results are detecting it as a flooder, wich is true, but not a malware!
