When we connect to address from task description, we need to guess some numbers. It seems like the numbers are 32-bit. I’ve done similar challenge before and I assumed that the goal of this challenge is to rebuild Mersenne Twister’s matrix state. I utilized RandCrack Python library to do that.
import socket from randcrack import RandCrack = RandCrack() rc = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s print("connecting") connect(("challs.dvc.tf", 3096)) s.print("connected") print(s.recv(256)) for _ in range(624): '1\n') s.send(b= int(s.recv(4096).decode().replace("Nice try! I was thinking of ", "").split("\n")) n print(n) rc.submit(n) = rc.predict_getrandbits(32) guessed_number print(guessed_number) "%i\n" % guessed_number).encode("ASCII")) s.send((while True: print(s.recv(4096))
