## Context
The image represents some kids that talk about the sky. Probably there is something in it
## Vulnerabilities
- Data hidden in RGB color planes
## Exploitation
I used https://stegonline.georgeom.net/upload to upload the image and analyze the RGB planes. The flag is hidden in the sky.

flag: `tjctf{l0l_st3g_s0_co0l}`
