There’s More Than Meets The Ear - Solution
- Download the audio file (
cool.wav) provided. - Open the file in Audacity and check the spectrogram.
- The flag should be there in plain text. Simply read it!
The submissions for this challenge were strangely interesting, although my peers and I thought this was a relatively easy challenge and the flag was easy to read.
But after reviewing the flags people actually submitted and the avalanche of tickets (+ DMs) I got just for this one challenge, I’m starting to suspect some of you were reading hieroglyphics instead of the flag. Either that, or the flag grew legs and ran away.
