Challenge

Theres something in the building: https://2019shell1.picoctf.com/static/aec3861fc4d5bce4d39dc0db196426de/buildings.png.

Hints

There is data encoded somewhere, there might be an online decoder

Solution

We have a file called buildings.png and we need to find a way to extract the flag for this challenge from our png.

Following the advice we simply look on the internet for an image decoder from .png to base64 (for example during this challenge we used this: https://stylesuxx.github.io/steganography/).

Within the obtained values we find the flag!
