SANS Holiday Hack 2018: Objective 10: Who Is Behind It All?
Objective: Who was the mastermind behind the whole KringleCon plan? And, in your emailed answers please explain that plan.
Answer: Santa
Access to the Vault:
The vault is protected via a “Piano Lock” as we have got the password from Alabaster’s SQL Lite database we attempt to play this on the piano.
E D# E D# E E D# E F# G# F# G# A B A# B A# B

Shame we haven’t got the write “key”? Alabaster provides us another hint:
“Really, it’s Mozart. And it should be in the key of D, not E.”
So as described in the PDF about how to play the piano from Alabaster’s e-mail, we have to transpose the password a whole step from E to D:
E D# E D# E E D# E F# G# F# G# A B A# B A# B
D C# D C# D D C# D E F# E F# G A G# A G# A
Playing this on the “Piano Lock” and we gain access:

And finally we get into the vault and meed Santa, who explains the whole plan.
