what a waste of a DDOS, they couldve hit soemthing big instead of soemthing over so little. those bots will die now from being overly used. they will ahve to make another. unless they used their friends botnet, which if it were my botnet and it got abused by a friend i would be heavily pissed.
of course im assuming whoever it is even has the knowledge and didnt buy the botnet from HF. either way, its a Script Kiddie motive in the end.
