Nowadays DDoS attacks became a profitable field of cybercrime activity.
You can find dozens of offers through search engines for eliminating competitors.
But what you do when kids attack your website ?
First off, I recommend you to not make enemies.
Do not insult any religious group of people, nor any other big groups of people.
But if somebody still attacks such a polite and smart person as you, do one of the following.
In all other cases the best strategy is to cooperate with your provider to block IP addresses of attackers.
You just send a complaint to your ISP. Your ISP complains to his uplink and his uplink in order forwards email to datacenters which host vulnerable servers.
Another thing you can do is to collect IP addresses of compromized servers, who perform attack on your website and send abuse reports to abuse@ email of hosting company. All hosting companies should have email like firstname.lastname@example.org
The following commands will help you to automate process of sending abuse emails.
