5. Open HID Lock

Introduction

Bushy Evergreen in the Talks Lobby

Oh, this might be a good time to mention another lock in the castle.

Santa asked me to ask you to evaluate the security of our new HID lock.

If ever you find yourself in posession of a Proxmark3, click it in your badge to interact with it.

It's a slick device that can read others' badges!

You know, Santa really seems to trust Shinny Upatree...

Objective

Hints

Solution

The first step in this challenge is to configure/hack the Santavator to get to Floor 1.5 where the Workshop and Wrapping Room are. The door with the HID lock is on the left in the Workshop. The Proxmark3 is on the floor in the Wrapping Room.
Proxmark3

The Proxmark3 can be accessed from your badge under "Items". Proxmark option on badge

Based on the comment from Fitsy Shortstack, the next thing to do is visit Shinny Upatree in front of the castle. If Santa trusts him perhaps he has a badge that can access all areas.

Standing near Shinny Upatree, with the Proxmark CLI activated, let's see if there is badge to be scanned.

[magicdust] pm3 --> lf search

[=] NOTE: some demods output possible binary

#db# TAG ID: 2006e22f13 (6025) - Format Len: 26 bit - FC: 113 - Card: 6025

[+] Valid HID Prox ID found!

[magicdust] pm3 --> lf hid read

#db# TAG ID: 2006e22f13 (6025) - Format Len: 26 bit - FC: 113 - Card: 6025
[magicdust] pm3 -->

Now back to the workshop to see if the door will open with the badge id ...

[magicdust] pm3 --> lf hid sim -r 2006e22f13
[=] Simulating HID tag using raw 2006e22f13

[=] Done

And with that the door opens.

Proxmark achievement

Answer

Scan Shinny Upatree's badge with the Proxmark and use the Proxmark to open the door to the "???" area.

Remarks

This is where things getting interesting. Stepping into the pitch black room there appears to be nothing there, but zoom out and you see 2 lights.

The lights

Drawn to the lights, you end up leaving the room and materialising as Santa in the Entrance Hall. You have managed to pass through the painting that is hanging in the Entrance Hall.

The lights

You can now access Santa's Black badge and you have the ability to teleport. This opens so much more access including the remainder of the Objectives.
