Description

"Agent! There you are. I got to take today off, sorry," said your elf mentor, "it's fine if I leave you at the office, right? It's a slow day anyways..."

Your curiosity, of course, led you to Santa's office. You step into his glacial abode where he is sleeping gracefully. Actually, he snores pretty loudly. Maybe, you'll find some of his secrets about children.

Should I peak into the unlocked file cabinet? Your intrusive thoughts won, of course.

You take out a document, only to find it scattered with emojis. Perhaps, Santa wants to better relate to the children of Generation Alpha? He should've used words like rizz, Diddy, and fein instead.

"That's Festive Encoding, agent," muttered Santa behind you.


Try decoding the excerpt under "2024 Encoded" in the file to reveal the flag. Once you do, probably use it for blackmail before you get fired.
