SEC-T Badge Puzzle is a new tradition of pen-brain-and-paper puzzles designed to be medium hard yet annoyingly easy to over analyse. The first person to solve a badge challenge will get two free entries to SEC-T of the year(s) of their choice. Currently there are different methods for submitting your answer, either by using the same webpage your ticket was downloaded from or by emailing [email protected]
If you believe you find a bug or are in a desperate need of a hint send us an email to [email protected]. To the extent that we give answers to any elements of the puzzle these answers will also be published here for everyone to see.
The 2018 badge challenge was delivered on an NFC tag. The challenge had a minor bug that could easily have been figured out. But because of that we have reprinted a fixed version below (base64 to preserve the data).
2020-05-02: It came to our attention that there was several issues with this challenge and a corrected version has been published here.

The badge puzzle was also printed as a poster for SEC-T 2019. This version has issues and should not be used.

The 2019 badge challenge was printed on one side of the plastic badge and so far no bugs have been found.
A member of audience came up to me and said they were there to “face me for two free tickets”. Clearly thinking this was the trick to winning.
I told them it wasn’t me saying this but that they instead should do what the card told them, to the card, and not to me.
Human: Who is Andy T?
SEC-T: There is no Andy T… it should be read as “and YT”
