Operation: The Mona Lisa Heist

This Operation has concluded and is now closed for participation. See our most recent Operation in the Operation Category for the ongoing event.


Jean sat at the head of the table, his eyes scanning the faces of the other thieves gathered around him. They were a tight-knit group, each of them skilled in their own particular area of expertise.

“Ok, listen up,” Jean said, his voice low and steady. “We’ve got a big job coming up. The Monet painting at the art museum in Wien. It’s worth a fortune, and it’s ours for the taking.”

There were murmurs of excitement and anticipation around the table as the thieves listened to Jean’s plan. They had pulled off some big heists before, but this was by far the most ambitious one yet.

“Here’s how it’s going to go down,” Jean continued. “We’ll need to get into the museum after hours, when the security is at its weakest. Once we’re inside, we’ll need to disable the alarm systems and grab the painting as quickly and quietly as possible. We’ll be in and out in under ten minutes, with the Monet in our hands.”

The thieves nodded, their eyes gleaming with excitement. They knew that this was going to be a risky job, but the potential reward was worth it.

“We’ll need to be careful and stay focused,” Jean warned. “There’s no room for mistakes on this one. But if we pull it off, we’ll be set for life. Are you with me?”

“Yeah!” the thieves shouted in unison, their fists slamming against the table.

Jean grinned. “Good. Now let’s get to work. We’ve got a Monet to steal.”

subject: Briefing “The Mona Lisa Heist”

Well good evening,

As you’ve probably heard in the news recently, the Mona Lisa was stolen from the Louvre Museum in Paris. Together with a variety of other high profile heists, INTERPOL believes these are all linked to the same organization. As of now we do not know which that would be. The most prominent paintings  recently stolen, which are believed to be taken by the same organization:

Watercolors – Marc Chagall

An Allegory – Sandro Botticelli

La Bella Principessa – Leonardo da Vinci

Portrait of Alexander Mornauer – Hans Holbein

The passion – Hans Holbein

Lady with an ermine – Leonardo da Vinci

The Annunciation – Sandro Botticelli

America Windows – Marc Chagall

The School of Athens – Raffaello Sanzio da Urbino

The Starry Night – Vincent van Gogh

American Gothic – Grant Wood

The Persistence of Memory – Salvador Dali

Mona Lisa – Leonardo da Vinci

The operations undertaken to heist these paintings have a lot of similarities. Camera footage is missing or replaced with seemingly still footage. Guards did not find anything, the alarms are disabled and no forced entries from the outside. CCTV footage is still being examined to find people who entered but haven’t left. So far it is believed the criminals wear disguises, even if we find unaccounted people, it might lead nowhere.

Given the camera’s malfunction, guards incompetence and alarms not going off, we suspect inside jobs. Or at least partially. This means interrogations are ongoing with all security personnel from the involved venues. We believe the only place these painting will show up are the underground markets, either online or offline. Regular buyers will stay away from these stolen goods. This leads INTERPOL to believe they are stolen out of personal interest, or to be sold to other criminals.

For months the case has gone without any leads. However, just this week, we were able to compromise an email account. The account contained one email. Forensics into this email did not lead my team anywhere. Which is why our hope of finding anything now rests with your team. We need your OSINT magic to figure out where the next heist will take place, so we can lay a trap for the thieves. Given their global profile, it is impossible to predict where they would strike next.

Here you find the contents of the email, please let us know what you find.

Alright one of the paintings we're going to hit has it's description hidden in the riddle that follows from the resolution below:

The Mona Lisa is one of the most famous paintings in the world, and its value is immeasurable. So when a group of thieves heard that the painting was going to be on display at the Louvre in Paris, they knew they had to act fast.

The leader of the group, a cunning and ambitious man named Jean, spent weeks planning and scouting the museum. He and his team mapped out the layout of the building, studying the security systems and studying the movements of the guards.

Finally, the day of the heist arrived. Jean and his team donned their disguises and made their way into the museum, blending in with the crowds of tourists as they made their way to the Mona Lisa.

As the guards watched the crowds, Jean and his team moved quickly and quietly, slipping past them and making their way to the painting. With a series of swift and precise movements, they removed the Mona Lisa from its frame and carefully wrapped it in a protective covering.

As they made their escape, alarms blared and guards ran towards them, but Jean and his team were too fast. They slipped out of the museum and into the bustling streets of Paris, blending in with the crowds as they made their way to their getaway car.

As they drove off into the night, Jean couldn’t help but feel a sense of pride and accomplishment. He had pulled off one of the biggest heists in history, and he was certain that no one would ever be able to catch him.

But little did Jean know, the authorities were already on his tail. It was only a matter of time before he and his team were caught and brought to justice.
