To be honest I think this one was a bit too straightforward, although it's a cute idea.
Santa released a new password policy (more than 40 characters, upper, lower, digit, special).
The elves can't remember such long passwords, so they found a way to continue to use their old (bad) password:

We got a zip archive containing a .ahk file. This is the filename extension for AutoHotkey scripts, which define keyboard buttons or keystroke sequences that when pressed trigger other virtual keystrokes in response. So we execute this script (ideally in a safe environment where it couldn't cause any harm if it were malicious) and in a text editor slowly type the old password and let AutoHotkey scramble it up as it replaces your keystrokes with parts of the flag until it's complete.
