Solution:
We've got an image with the challenge, and we found a flag: "IHC_CTF{This_is_not_flag}". However, that's not the real flag. To uncover the actual flag, we're attempting steganography on the image.
To discover the actual flag, we're trying steganography on the image.We're using this website: https://futureboy.us/stegano/decinput.html
While performing steganography, the image requests a password. We're inputting the fake flag as the password.
By using the fake flag as the password, we successfully discovered the real flag in the output.
