Never thought I would say this but this is a creepy contract. Nevertheless it will be easy if you know the basis of steganography.
I tried to find some clues in the video but it was dark and had no audio. I thought it could be a broken file. Tried to fix it online but was negative. Since the contract says that no audio was found I tried to extract the audio but was negative too.
I decided to download the video to Kali and use exiftool to see what I can extract.
Found an interesting clue in the comment section of the output.
Use this as the password for the linkfile and you will get the contract card.
