Hey all,
I recently ran a puzzle contest over here: https://hackforums.net/showthread.php?tid=5475443
The purpose of this thread is to get some feedback as to what you guys think of these ARG-type puzzles as opposed to the "Decode this from X to Y then from Y to Z" style I see quite often.
Spoiler Warning: Although the competition is over, if you would still like to attempt the challenge, stop reading now.
Step 1 This step simply involved either highlighting the text or quoting the original post:

Step 2 Another introductory step, converting this hex into ASCII provides the following link: http://pastebin.com/FUTw3CLa
Step 3 This step involved extracting the capitalised charaters from the pastebin and using them with the Tinyurl link ![[Image: ENgHapz.png]](https://i.imgur.com/ENgHapz.png)
Step 4 Similar to the null cipher in step 2, this involved taking the first letter of each sentence and adding it to an imgur link. ![[Image: tq7ch7j.png]](https://i.imgur.com/tq7ch7j.png)
Step 5 After going to the imgur link, one can either squint at the corner or just playing around eith the levels/curves to reveal an email address. ![[Image: Vwd04H1.png]](https://i.imgur.com/Vwd04H1.png)
Step 6 Once emailing the given address, they'll recieve the following reply:
HZMGZHSVOKVI185@bash:~$ help
help: command not found
As you can see, this is presented in the vain of a Linux terminal.
This is the first step that requires a bit more lateral thinking to get through as one needs to identify that @bash is actually hinting towards the common cipher known as 'AtBash'. Entering the code into a translater such as this: http://rumkin.com/tools/cipher/atbash.php provides the following: SANTASHELPER185
Step 7 The code given follows very similar tendencies of online usernames. After trying the username on the 'top tier' social media websites, it's reveled to be a Twitter handle: https://twitter.com/santashelper185
Our dubious hacker may have the skills it takes to take over Santa's server farm, but hasn't yet figured out how to delete a tweet. On the timeline, the youtube code "1zMLo5t_M5s" is given. Fun fact, to get an underscore in the URL, I had to reupload the video 15 times. I wanted there to be a non-alphanumeric character to allow people to cross out a few options
Step 8 After getting some inspiration from the video, the next challenge is to figure out the icon of the youtube channel has a link: http://pastebin.com/sUzUPMeW
This was actually available after receiving the email, though they wouldn't be able to complete the puzzle without finding it via the youtube video.
The clue in the image requested 'help'. This was a hint towards the HF Help Docs. From there, using the array notation provided on the pastebin from the last step highlights the following: ![[Image: tvn07Wl.png]](https://i.imgur.com/tvn07Wl.png)
Step 9 The resulting tinyurl links to the address "http://0.49.175.246/". Obviously this isn't going to work, to get any useful information from this it needs to be converted to base 10: 3256310
Step 10 This number then links to an old thread of mine: https://hackforums.net/showthread.php?tid=3256310
One of my less subtle clues, but I mentioned 'readit', meaning Reddit. As well as giving a username. One of the comments of this user provides the final url: /= 4j7fCDRV + 1zMLXXX?X??X?X?XAECORRUPT
Step 11 Let's start with the first part of the link, "4j7fCDRV ". This can be followed to a pastebin link: http://pastebin.com/4j7fCDRV.
To solve this, the weighted total of these brackets must be calculated. It's possible to do this by hand... though I'd reccomend just writing a small script to do this. After assigning values to ( and ), the result is 246.
Step 12 If they found the youtube url, this is a fairly simple step. If they didn't, there might be some struggling until they figure out the remaining half of the url. Going back to santa's hacker's favourite video and checking the page's source, we can see that the video contains a tag called 'naughtysanta', not visible in the description.
Visiting the combined link (tinyurl.com/246naughtysanta) takes them to a link to post the top secret password to the thread.
Big congrats to MeshCollider for being the first to crack the code.
I'd also like to give Wares and Yoyo a little shoutout for their progress, the last couple of challenges were a very close race 🎉
I'd love to hear everybody's feedback on this, especially so the types of puzzles involved, their difficulty and the overall competition length.
Cheers 🤝
Very interesting walkthrough, its funny the things I actually missed like the Imgur down the side of the sentences in step 4 haha. Step 8 was definitely the hardest for me personally, had to get so much hints before we worked it out
DO NOT DEAL WITH THIS MEMBER
Thanks for finally letting us know how to do it!
If you decide to make another in the future, try to not have clues for later steps in earlier steps (i.e. the pastebin link in the profile picture, as that's what confused me and a few others)

Cheers 🤝 This was an amazing Challenge! Really fun, the last 2-4 steps were really tricky :P
Gratz to @Mesh to winning this :P
