So, I'm a not very experienced hacker, I've learned a couple of things, but I would love to know how to DDoS attack any servers, in-game server, websites, etc. And yes, I've already seen this, and this isn't actually a DDoS attack; ping (IP Address) -t -l (Number). I would like how to ACTUALLY DDoS attack, and I mean I want to be able to crash, or make game servers or websites EXTREMELY SLOW/LAGGY I don't want things like LOIC, that only DDoS attacks you're own device.
