Day 5

warmup/unbelievable

We are given a .mp3 file, and the hint “Don’t believe everything you see on the internet”.
The later means the extension file is not reflecting the real file type. In fact, by using the file command, we can see it’s actually a PNG image file:

$ file Half-Life_3_OST.mp3
Half-Life_3_OST.mp3: PNG image data, 800 x 200, 8-bit/color RGB, non-interlaced

Opening it with an image viewer, and here’s the flag! We just need to write it down.
