Description:

Do you know about steganography? Steganography means not only hide message in image but also in audio.

Solution:

Listening to the audio, there doesn't seem to be anything unusual. Our next step is to open the file in Audacity and check the spectrogram.

We can read the flag from the spectrogram.

Or we can use this online tool:
