TFI 001

First of all, go and read TFI 000 to understand what you are reading.

You can find the first challenge on the front page, so you can see it by looking for images on the Internet.

At the bottom right corner, you can see something that looks like a URL without letters.

If you have seen «characters» like those before, you know what it is. If not, you can try to describe them to ChatGPT or another LLM. If you do it well enough, you will get the answer.

It is an encoding typically used by some ancient groups (rabbis, Knights Templar…) that you can decode by drawing two tic-tac-toe boards and two big Xs.

If you translate the URL, you will go to a page that shows your reward code and a new challenge.

The new one is made of three images with lines of different colors: one red, one green, and one blue. If you know something about computers, you know that images are created with a combination of three colors: red, green, and blue.

You can solve this challenge using any image editing software that supports layers. You just have to stack the three images and adjust the transparency to see the combination of the three, which is a password that will give you a new redeem code.

This first challenge is really easy, but you need some previous knowledge about computers and cipher systems.

See you next week with a new challenge.
