Problem statement

La Búsqueda de la Forja Élfica Olvidada 🧝‍♂️

Año 3018 de la Tercera Edad

La Tierra Media está al borde de la guerra. Las fuerzas de Sauron reúnen fuerza, y el Anillo Único ha sido encontrado. Sin embargo, en lo más profundo de las historias olvidadas de los Elfos, hay un secreto que podría inclinar la balanza del poder: una forja oculta, utilizada una vez para fabricar armas capaces de resistir el poder del Señor Oscuro.

Los antiguos escritos hablan de un acertijo, uno que solo un verdadero maestro de las letras puede resolver, revelando la entrada a la forja. Tu misión es descifrar las pistas y descubrir las credenciales ocultas que te permitirán pasar por la puerta élfica y entrar en la forja.

Al llegar a la entrada del templo, encuentras una puerta de piedra tallada con runas élficas. En el centro de la puerta, un poema está grabado en una lengua antigua, y debajo de él, un campo en el que puedes ingresar un usuario y una contraseña.

El poema, escrito en un idioma perdido, reza así:

The Keeper of Secrets, Elven Lore,
Guards the door to ancient war.
A name in whispers, subtly veiled,
The key to forge the fading light.

A password cloaked in shadows deep,
Where truth and trust in darkness sleep.
Reveal the word, but tread with care,
For only those who dare to stare.

Through webs of spells and runes that guard,
The path to wisdom, worn and hard.
The quest is yours, the way is paved,
By username in light engraved.

Password bound by hidden might,
Shift the veil, and find the light.

Debajo de la puerta, encuentras un campo para ingresar un usuario y una contraseña.

Usuario: ??? Not all those who wander

Solution

Analyzing the Riddle

The poem is a riddle that talks about something hidden somewhere. We need to find the hidden credentials to pass through the door. Since we don't have an API to interact with, we can start with the username and password fields.

  1. Username Analysis:

    • The username field shows "???" since something is hidden. Let's check the console for clues.
    • Nothing interesting in the console. Let's try to find the hidden text in the API calls.
    • Nothing interesting in the API calls. Let's try to find the hidden text in the HTML.
    • Boom! We found the hidden text. It's "Not all those who wander" written in white color, so it's "invisible."

  2. Password Analysis:

    • The password field is shown as an input with some dots. Let's check the console for clues.
    • Nothing interesting in the console.
    • Let's try to find the hidden text in the HTML like we did with the username.
    • Boom! We found the hidden text. It's "are lost" as part of the value of the input.

The Answer

  • Username: Not all those who wander
  • Password: are lost

Let's submit the answer:

curl -X 'POST' \
  'https://makers-challenge.altscore.ai/v1/s1/e4/solution' \
  -H 'Content-Type: application/json' \
  -H 'API-KEY: API-KEY' \
  -d '{
    "username": "Not all those who wander",
    "password": "are lost"
  }'

And the response is:

{
  "result": "correct"
}
