I have recently been a victim of an internal TCP Flood Denial of Service attack, yet I can find next to nothing on it scouring the net. A machine on my internal network was flooding my routers with packets, causing our Internet connection to go down. All antiviral and spyware (spybot, ad-aware) scans have come up clean. I think I have stopped it using the Windows XP firewall, but am not sure.
What is this form of attack?
Where can it come from?
How can it be stopped?
Where can I learn more about it?
