Blue Herring

I found it quite easy to try downloading it and checking it out

Use zsteg and i found it .-.

zsteg --all BlueHerring-CPmowcv1.jpeg

Medieval Beats

After checking, the flags are randomly hidden inside the video, download it, and use ffmpeg to process the images.

ffmpeg -i y2mate.com\ -\ Flag\ Vido_1080p.mp4 -vf "fps=1" output_%04d.png

The black ones have 6230 bytes of data, delete it

find . -type f -size 6230c -exec rm {} +

That’s right, now there is a flag

Wario Party

Using Aperi’ Solve to check, I found that on the second bitplane something was encrypted

Use StegOnline to extract it

I guess maybe it’s binary .-. manually go into CyberChef and see what it comes up with
