黒い線が10で割って7になるピクセルの行に多くあるので、その行だけ取り出して結合してみる。

Error 0 (Cryptography 150)

2進数をデコードすると、ところどころにフラグの断片が見える。101回メッセージを出しているが、ノイズがあるということなので、同じ位置の文字で最も頻度が高い文字を採用する。

    enc = f.read()

for i in range(0, len(enc), 8):
    data += chr(int(enc[i:i+8], 2))

Random Number Generator (Cryptography 250)

time.time()を使ったseedを使った乱数で、rで実際のランダム値を取ることができる。実際のランダム値と比較して、time.time()の値を探りあて、1回目と2回目のランダム値を予測する。

#!/usr/bin/python3
import socket
import random, time

def recvuntil(s, tail):
    data = b''
    while True:
        if tail in data:
            return data.decode()
        data += s.recv(1)

seed = round(time.time() / 100, 5)

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('challenges.ctfd.io', 30264))

data = recvuntil(s, b'\n> ')
print(data + 'r')
s.sendall(b'r\n')
next0 = recvuntil(s, b'\n').rstrip()
print(next0)

while True:

    if r == int(next0):
