That’s a scenario I imagined when I read this BBC NEWS article… I’m sure n00BS in here will refer to such action when they get their ass kicked by p0wn3r5!!
Hackers are starting to sell some DoS tools for Xbox live users so n00BS could flood other players (When they get their asses kicked by them) and get their connection disconnected due to flood…
Microsoft is investigating this matter and it’s banning and\or taking other measures to whoever commit such action…
The thing is, it’s abit of hard to figure out a player’s IP Address because you connect to the Xbox Live service and the servers aren’t privately hosted (Not by private servers neither users)… Hackers usually figure IP Addresses by cons and packet sniffers (Wireshark maybe? 😛 )…
Such attacks are usually performed on servers and websites… But now you can add XBox live users…
There’s no easy way to solve this ofcourse since DoS can be really tricky, but Microsoft are working on things…
