The other #holidayhack there is the chocolate covered gummi bears. That hack is just simply eat them while hacking. :D

Oh nice, this years #SANS #HolidayHack challenge is live.

I can once again take the opportunity to practice fluidly transition between the boolean states of InfoSec Peeps, SicSkillz and N00b 5cr!ptK!dd!3.

Alright #HolidayHack #CTF fans, are you ready?! It's launching soon, and I was able to spend a day with the CounterHack elves as they put their final touches on this year's game! To celebrate I am releasing my CheatSheet earlier than ever: bit.ly/HolidayHack2025

Loved the new #HolidayHack format this year, releasing challenges in 4 acts! I'll hack web and JS, curl and PowerShell, hardware and mobile apps. There are two SOC / SIEM like challenges, and ransomware decryption.

The Chrome Local Overrides feature is very cool. Use local files to mock out HTTP requests in the dev tools.

What better place to play with this than the #HolidayHack Snowball Showdown challenge in Act 2. Watch it now (Act 3 is live!):

The PowerShell terminal is one of the most difficult challenges so far in #HolidayHack. Lots of interacting with a webserver and parsing data.

With the opening of Act 3, my video solution is now up on YouTube:

With the start of #HolidayHack Act 2, three YouTube Videos from Act 1 are now live!

I'll walk through the cURLing challenge, brute force a pin on the Frosty Keypad, and show a neat Easter egg in the Shreds image metadata.

In the Elf Connect challenge from #holidayhack 2024, I'll hack a Elf game based on the NYT connections game. I'll show some basics for browser dev tools, and a couple ways to cheat the game.

Being away from home sucks, but could be worse :D

I had so much with playing the
SANS #HolidayHack challenge this year. A lot of AI focus. I still can't believe how easy it is to make a fake voice clip (which is one of the challenges). Also some good examples of ChatGPT just being wrong!

Bawls and cold pizza to start the day. I am pretending to be half my age yes. It also fuels the hack.

Time to tackle the SANS Holiday Hack Challenge with my buddy!
