DownUnderCTF-On the Spectrum(Forensics)

·1 min

Recently, I’ve been getting hooked with forensics challenges, this being the second solve I made for the team.

The challenge description is as follows

“ My friend has been sending me lots of WAV files, I think he is trying to communicate with me, what is the message he sent?”


The challenge description was already a hint and I pinpointed this to spectrum steganography. Audacity is a popular tool used to analyze waveforms and spectograms

the audio file

audacity link to download

Proceeding to open the .wav file with audacity and viewing it as a spectorgram, we get the flag!


Happy hacking :)
