## Challenge
Welcome to the RCTS Challenge!

Can you find the flag?

Flag format: flag{string}

## Solution
Using the `Extract Files` operation in Cyberchef on the given image file, we see that it might contain 6 files including a png file.

Clicking this png file, gives us the flag.

So the flag is `flag{0n3_1m4g3_1s_n0t_3n0ugh}`
