Okidoki, a forensics challenge with a video. Let's try to open it and see what we've got.


DAMN IT, they got me.

Might as well watch the video to see if there's anything obvious. Around 2:20 into the video, there are some noticeable audio distortions.

To extract the audio from the mp4, we can run the following: `ffmpeg -i OldFavorites.mp4 OldFavorites.wav`

We need it as a *wav* file so we can open it with Sonic Visualiser and/or Audacity and check what's going on. So let's open it up and see what we can see around 2:20 in the audio. With these kind of challenges there's often something in the spectrogram, so we will first view that.


Well, there it is `sun{you_know_the_rules}`
