I teach blockchain at Elf University at the North Pole, and I can't imagine even I could've created a clearer and more easily understood examination of what Jack Frost did in 2020 to undermine the Naughty Nice blockchain. A wonderful video. Bravo! #HolidayHack KringleCon

Join the gang from Counter Hack , several KringleCon speakers, and a whole bunch of other folks for the Holiday Hack Challenge Closing Ceremony! Hope to see you there, in game, in the courtyard of Santa's castle! Counting down the hours! #HolidayHack

Congratulations to everyone who played!

Congratulations to the great folks at Counter Hack ! Working with all of you amazing people was the highlight of my holiday season. Thank you for everything you do! Looking forward to the next 11 years and beyond!

This silly ol' elf is so grateful that the fine folks Counter Hack and the SANS Institute asked him to contribute to #HolidayHack and KringleCon again in 2021! What great people to work with! Best of luck with the upcoming launch!

I just watched this: youtube.com/watch?v=E5nX5s… Looking good, edskoudis ! Thank you, again, for including me in KringleCon ! Best of luck with this year's #HolidayHack !

So, edskoudis , I noticed that there seem to be a lot of people hanging out in and around Santa's castle. Did the folks Counter Hack do something? #HolidayHack

I thought it was looking more crowded up here at the North Pole!

Thank you for your kind words, Jay! I can also heartily recommend Jay's talk on Hacking Kubernetes. You'll learn SO much about K8s!

So honored to have been invited to participate in this year's event and to be included in this list of amazing folks!

You, edskoudis , Joshua Wright and the whole crew Counter Hack are amazing to work with and make KringleCon and #HolidayHack so very wonderful. And, on a personal note, thank you for all of your help over this past year!

The incredible team Counter Hack worked together to create both red- and blue-focused bonus challenges around the log4j vulnerability. They asked me to put together a short presentation and how could I say no? KringleCon #HolidayHack youtube.com/watch?v=OuYMPU…

Think of it this way: The log4j library doesn't really have a vulnerability. It just provides your application with a previously undocumented "plugin" mechanism. See my video: youtube.com/watch?v=OuYMPU… #HolidayHack KringleCon #log4j

It was wonderful working with the Counter Hack team. They did amazing work, adding log4j challenges to #HolidayHack in record time. I just threw together a presentation.

I'm so glad you enjoyed it! Have a wonderful holiday and thank you so much for your efforts (and the efforts from the entire team at Counter Hack ) for putting together another fantastic #HolidayHack Challenge and KringleCon

I want to offer a hearty "Congratulations!" to everyone who completed the SANS #HolidayHack and KringleCon challenges. Even if you didn't complete all of the challenges, you got to exercise your brain, and learn something - so, in this Elf's book, that makes you a winner too!

Woohoo! This Elf can't wait! If you want to know the minute HHC officially launches, you can sign up by following the link in this post!

Once again, I'm deeply honored to have been asked to speak at #KringleCon and help out with #HolidayHack. You might find my new GitHub repo to be helpful down in the depths of the Burning Ring of Fire github.com/QPetabyte/Merk…

This hat buying thing is pretty addicting. You need to check it out! 2022.kringlecon.com #HolidayHack KringleCon
