Stop Drop and Roll Writeup

Challenge description:

The Fray: The Video Game is one of the greatest hits of the last... well, we don't remember quite how long. Our "computers" these days can't run much more than that, and it has a tendency to get repetitive...

This challenge is playing a game in which we have to input based on the challenge question. For example if it says GORGE we need to respond STOP, if GORGE, FIRE we need to send STOP-ROLL and so on till we finally get the flag.

    #! /usr/bin/python3
    from pwn import *
    
    IP_ADDRESS = '83.136.252.248'
    PORT = 54677
    
    conn = remote(IP_ADDRESS, PORT)
    
    print(conn.recvuntil(b'(y/n)').decode())
    
    conn.sendline(b'y')
    
    print(conn.recvline().decode())
    
    responses = {
        'GORGE': 'STOP',
        'PHREAK': 'DROP',
        'FIRE': 'ROLL'
    }
    
    while True:
        prompt = conn.recvline().decode().strip()
        print(prompt)
    
        if "What do you do?" in prompt:
            keywords = prompt.split("What do you do?")[1].strip().split(', ')
        else:
            keywords = prompt.split(', ')
        
        response_keywords = [responses.get(keyword) for keyword in keywords]
    
        if None in response_keywords:
            break
    
        response = '-'.join(response_keywords)
        
        conn.sendline(response.encode())
        print(f"Response: {response}")
        
        if 'Unfortunate! You died!' in prompt:
            break
    
        if 'Fantastic work! The flag is' in prompt:
            flag = prompt.split('Fantastic work! The flag is')[1].strip()
            print(f"The flag is: {flag}")
            break
    
    conn.close()

The flag is: HTB{1_wiLl_sT0p_dR0p_4nD_r0Ll_mY_w4Y_oUt!}
