Multi-vendor Game Server (GameSpy) DDoS Attack
w4rl5ck writes "PivX has this security advisory about DDoS attacks using a single modem line and some game servers (i.e. Counter Strike, QuakeX, Battlefield 1942 - in short, those supporting GameSpy). Works via spoofed udp packages querying the server stats, and because udp is connectionless, the server simply answers - to the spoofed address, of course. Funny thing, isn't it?
