Just Game PWN using srand() on libc, we can get the same random number with ctypes

```
from pwn import *
from sys import *
import ctypes
import time

context.terminal = ["tmux", "splitw", "-h"]
elf = context.binary = ELF("./mr_unlucky")
p = process("./mr_unlucky")
libc = ELF("/lib/x86_64-linux-gnu/libc.so.6")

HOST = '52.59.124.14'
PORT = 5021

cmd = """
b*main
"""
if(argv[1] == 'gdb'):
gdb.attach(p,cmd)
elif(argv[1] == 'rm'):
p = remote(HOST,PORT)

LIBC = ctypes.CDLL("/lib/x86_64-linux-gnu/libc.so.6")

LIBC.srand(LIBC.time(0))

# Sleep for 3 seconds
sleep(3)
# List of heroes
heroes = [
"Anti-Mage", "Axe", "Bane", "Bloodseeker", "Crystal Maiden",
"Drow Ranger", "Earthshaker", "Juggernaut", "Mirana", "Morphling",
"Phantom Assassin", "Pudge", "Shadow Fiend", "Sniper", "Storm Spirit",
"Sven", "Tiny", "Vengeful Spirit", "Windranger", "Zeus"
]

for i in range(50):
v6 = LIBC.rand() % 20
ans = heroes[v6]
print(ans, v6)
p.sendlineafter(b'!): ', ans)

p.interactive()

```
