Description

Currently, storing important information is something extremely simple. It can be on a mobile phone, a USB drive, a computer, written on a piece of paper, or even hidden within a simple photograph. But... what if one day possessing this information could cost you your freedom?

Story

In a strange future, after a series of global financial crises, various governments decided to take absolute control over the digital assets of their citizens. Anyone found storing certain types of encrypted information could have their assets confiscated, face criminal charges, and lose the right to leave the country.

Your uncle Exif knew this would happen. Exif was an expert in cryptography, information security, and digital privacy; he spent years studying ways to protect what he considered most valuable. Then, he realized it would only be a matter of time before his freedom was taken away, so he decided to flee to one of the few countries that still respected the right to private property. Days before the trip, he prepared everything carefully. Knowing that any document could be confiscated during an inspection, he made an extreme decision. He would never leave his most important information gathered in one place. Instead, he divided everything into small parts, spreading clues across different media.
A few hours before leaving, he sent me a single voice message for you.

"Hi my nephew, if you are listening to this... it means something went wrong. Do not look for what I hid. Only look for the clues. When all are gathered, you will understand."

Nothing makes sense in isolation. Everything I investigated seems to hide only a small piece of a much larger information. Everything is somewhat abstract. Your uncle promised that as soon as he crossed the border, he would make contact. That contact never happened. Days later, the authorities released news of a serious accident. He did not survive. For years, that file remained forgotten. Only now have we decided to uncover what he really tried to hide.

Your mission

You have just received exactly the image your uncle left. There are no instructions. There is no manual. There are also no guarantees that everything is exactly as it seems. It will be necessary to observe almost imperceptible details, interpret hidden messages, analyze images, investigate if there is anything else in the message, use steganography tools, and understand modern cryptography techniques to hide things.
