Hope your vacation went well! It’s good to have you back, we’ve got an unusual job for you that has the highest priority. You’re probably familiar with the Cicada 3301 puzzles from years ago. The internet hype that had people chasing around the world.
So, recently we’ve discovered what seems to be a recruitment effort by one of our competing agencies. Dimitri and his team have some indication that they’re based in France, but we’re not sure about this. They’ve taken a name close to Cicada, well the same but in French, and added different numbers.
It seems they’re using this as a recruitment tool to find new talent. As it stands, the market is fairly tight to find good OSINT people and hackers alike. With world war three kicking off, everyone needs more intel people.
Since this undermines our efforts of hiring the best people, HR asked us to find out what this puzzle is all about. Basically we want to complete it, understand it and possibly figure out who’s behind this. Most importantly, to figure out the actual puzzle. This will give us an estimate of the level of expertise our competitors are looking for.
There’s a slim chance of uncovering their shady puzzle. Below you find a link. It’s a password encrypted file with a riddle attached. Unfortunately that’s all we have, but I’m sure you’ll figure it out from here.
Good luck and happy hunting,
Head of HUMINT Operations
