These recent attacks all work by overloading the server with UDP packets.
Most effective are the A2S_INFO and similar attacks using valid packets.
It's very cheap in terms of CPU and bandwidth to craft a packet that asks a
gameserver for it's information. It takes a number of times more CPU power
to generate the response.
It only takes a simple connection with about 3Mbit upstream to take down any
OrangeBox gameserver.
does this form of attack use the game ports?
or just hammer the IP?
Reason I ask is the attacks appear to be simply hammering many different
ports and coming from hundreds of IP's simultaneously. For all I can
see, it's a DDoS...
