Miss this one a lot.

Unfortunately, this puzzle requires you having the 10 NFC tags I am programming. I am attaching my full notes and solutions to this puzzle.

Description: Welcome to the modern era of physical security and access control. Before you lie ten NTAG215 NFC tags, physically numbered 1 through 10. One of these tags contains the system override phrase. The other nine are decoys.

Reading the tags is the easy part; understanding them is the true test. The data payloads on these tags are obscured. To reveal the true messages, you must realize that the hardware itself holds the key. The cipher changes from tag to tag, bound by the physical identity of the chip and the current era.

Your Objectives:

Interrogate the Hardware: A standard smartphone tap will only show you the encrypted text. To find the key, you must use a Flipper Zero, a Proxmark3, or an advanced smartphone application…

You will need the attached QR codes to complete this.

Description: You have bypassed the physical hardware restrictions and secured the initial foothold. Now, you must escalate your privileges to absolute control.

Hidden in the physical environment are five sequential data drops in the form of QR codes. A standard smartphone scan will yield a Base64 string, but that is merely an encoding wrapper. The true payloads are heavily encrypted.

You must establish an air gap protocol to transfer this data to your terminal. Your cipher is AES-256-CBC with PBKDF2. The payload from the first drop will contain the passphrase to decrypt the second, chaining all the way to the final target.

Find the drops, decode the wrappers, decrypt the network daemons, and claim root access.
