I was wondering if someone can become a victim of a DDoS attack as home user when only his IP is known by the attackers but he is behind a router with no open ports or other known vulnerabilities?
I'm mainly interested because this becomes more and more a topic in professional gaming (which I like to watch). But my feeling is that the players often claim to be DDOS'ed without having a clue if this could be possible and the real reason most likely is that their connection is just bad/there are technical problems. On the other hand, there is a lot of money involved in those matches so ordering a botnet in a price range from $1000 - $10000 for the time of the match could indeed be attractive for some people...
So, is this possible or not? And if it is possible how can it work and are there effective counter measures (other than changing the private IP and not logging in to services afterwards over which the attackers could have get knowledge of the IP)?
Thanks for answers!
