This is a popularized Discord exploit that abuses the analytics sector of Discord. If any of you had half a brain, you would know how this works. Since you don't, let me explain
First, we connect to the discord gateway so we have to keep sending heartbeats and discord will respond with an opcode or "operation code". We can send a specially crafted packet which prompts the server to send us an analytical opcode, to which we respond with the users ID.
The server will then send back their authentication token encrypted with a key. Since it can be locally decrypted and the key is only 4 - 7 letters long in every case (depending on when their account was made) we can easily bruteforce it.
