I found the original video. It's here: https://www.youtube.com/watch?v=3rysbn9bZ54

Riffing off of that, I've tried these passwords, including the 2*sha256 versions of them. None of them worked for me:

i think we need to decode the encoded 2mb splittet from the Space.mp4...

maybe that is also needed for it:

And then there was Bitcoin
Monsters!
space
more words
Muhahahhaa
Satoshi was here
That's all there is to it!
Such Wow!

if it is the last puzzle, then it is for shure the hardest from all!

maybe something like xor the data with every words in rigth order...

FWIW, there's another QR code spectrographically hidden in 25_chirp.wav in the DoD game. It's the same code that arg found in Elements.jpg that led to Again.7z. This leads me to believe that the DoD branch is the red herring and the Space.mp4 branch is the endpoint.

I also think that. The question is what to do with that 2MB of data in our hands.

For completeness, same goes for 24_clash.wav.

I try opening it and it prompts for a password.

I subtracted 100 because in several examples of .7z files I have, there was a section of 00000$0000000 a few bytes in.

But this raw data has ddddd<8d>ddddddd which to me looked like it was rotated. That means subtracting 100 bytes. And voila, I see a correct 7zip header at the start!

Someone try running my program on Space.mp4 and let me know if I'm not totally insane here....

I'm going to try variations on what came out of the video for password.

I extracted another 7z file from the Space.mp4 by subtracting 100 from each byte of the last 2147129 bytes (which matches exactly the split.bin posted earlier)

Please someone confirm this!

Why 100?
Just do it and check if it opens...

But I wouldn't suggest you brute force anything.

Pardon my bad code:

#include

main()
{
FILE *f = fopen("Space.mp4","r");
FILE *f2 = fopen("another.7z","w");

int l = 9356135-2147129;
int c = 0;
while (c < l) {
fgetc(f);
c++;
}

int q = 0;
while (q < 2147129) {
fputc(fgetc(f)-100,f2);
q++;
}
printf ("done\n");
fclose(f);
fclose(f2);
}

Please someone confirm this!

Portrait is a "shared start point." Google is your friend.

I think we didn't focus on this!
However I can't get any noteworthy results from Google Huh

that was the very first hint ..

Can someone re-upload this container on other site? Had an unknown SSL error (ssl_error_rx_record_too_long) when connecting to this site (both browsers), not know how to solve at this time.

Thank you! But there is an win32 executable downloader, can not run this. Angry

There's definitely some kind of file/data embedded in Space.mp4, with ffmpeg, I can do:

...

In addition, I think I found the original copy of the video file (before extra data was embedded into it):

...

9356135-7209006 = 2147129, which is the number found in Number.txt

So, there are 2147129 bytes of additional data besides the audio and video streams in Space.mp4

...

Edit: extract the extra data with this:

Code:

dd bs=1 skip=7209006 if=Space.mp4 of=binary

Fantastic work, congratulations.

Hope this works, now try. Thank you too. От души.

click on the file name split.bin on the page (right beside Download)

not on this freeky download button at the bottom!!
