PRO TIP from Santa's helper:
Are you making a Word of the Day list, and checking it twice? -
We had another sponsor join in on the fun and donate towards the Grand Prize. That brings the prize pot up to
0.158879 ETH... which is currently$464 USD!It's not too late to join the fun and have a chance at winning the Grand Prize! Just make sure to go back and start from Challenge 01.

UTC: 2025-12-24T13:57:32ZDear Santa Claus, why so many dits and dahs? Does hashgen support this mode?
PRO TIP from Santa's helper:
Oh my, you are not going to like the challenges ahead for two reasons:
11. Not everyone parses hashes the same, so prepare to be annoyed.
12. Things will be very difficult if you haven't found the source. -
Merry Christmas Eve! 
The easy part of the Challenge is coming to an end, and everyone should find the upcoming Challenges a bit more complex to solve. Don't let that discourage you from continuing though as there's still more prizes to be won.
With that said, let's consider the "gentlemen's agreement" over, and all bets are off on who finishes Challenges 11 and 12!

Challenge 11 - HINT
UTC: 2025-12-25T01:46:03ZBlitzen introduced me to this bloke 2day at our Christmas party. He's supposed to be the fastest hash around, but the word around Santa's Workshop is that hashcat doesn't like this hash's format as-is, and the submitter doesn't like hashcat's format! What a joke! Why can't everyone just place nice?!
Make sure to submit hashes back in their original format and order!PRO TIP from Santa's helper:
You'll be completing the 12th challenge soon and unlocking the latest hashpwn wordlist, but somewhere, hidden in plain sight within these 12 challenges, will be a 13th puzzle which is the Grand Prize. Good luck finding it! -

- Read https://infosec.exchange/@cyclone/115289515912035341
- Use a BIP39 wordlist.
Huh, now why would I need a BIP39 wordlist, and what's going on with the 12 Words of the Day? I'm starting to think these don't have anything to do with the 12 Days of Christmas after all!
Meanwhile, congrats on making it this far! You can now download the latest hashpwn-2025 wordlist:

Congrats to all those who played along and completed the Challenges!
I can conform that Challenges 01-12 have been solved, and the final hidden Challenge 13, aka the Grand Prize, was found yesterday and claimed by @_cin ! If you are still working on any of these, feel free to continue as the Challenge server will be left online for a few days. I'll post the final submission entries as well before shutting down the Challenge server.
Everyone is also welcomed to share your thoughts on this year's challenge and your process for working through them.
This completes the 12 Days of Christmas Challenge. Thanks for playing along!
PS
The hidden Challenge 13, aka the Grand Prize, was a seed phrase from the 12 word of the day Challenges. Congrats to those who figured this out!
