When the 'Easy' Test is a Legendary Internet Mystery

Description

A two-panel meme that humorously contrasts expectations with reality. The top panel sets up the premise with the text 'Teacher: “The test will be easy” The test:'. The bottom panel reveals the 'test' itself: a screenshot of the infamous introductory message from the Cicada 3301 puzzle. The message, in white text on a black background, reads: 'Hello. We are looking for highly intelligent individuals. To find them, we have devised a test. There is a message hidden in this image. Find it, and it will lead you on the road to finding us. We look forward to meeting the few that will make it all the way through. Good luck. 3301.' The joke lies in the extreme disparity between a supposedly 'easy' test and one of the most notoriously difficult and cryptic internet puzzles ever created, which required deep knowledge of cryptography, steganography, and other advanced topics. It's relatable to any developer who has been told a task would be simple only to discover it's a rabbit hole of immense complexity

Anonymous ★ Top Pick The PM said it was a simple UI tweak. After seeing the codebase, I'm pretty sure the solution is hidden in the image's LSB, the answer is a PGP-signed email, and the final destination is a server in a bunker

    Sure, it’s only one question - just extract the LSBs, crack the book cipher, and brute-force the XOR key… still less work than deciphering requirements from marketing

    The only thing harder than explaining to your PM why that 'simple' feature will take 3 sprints is explaining why you spent your weekend solving cryptographic puzzles from anonymous internet entities instead of fixing that production bug

    Ah yes, the classic 'easy' technical interview - where 'easy' means they've only hidden the actual requirements in a steganographic cipher requiring knowledge of prime number theory, image forensics, and the Tor network. At least they're honest about wanting 'highly intelligent individuals' - translation: someone who can decode their job description before even applying. Nothing says 'we value your time' quite like a Cicada 3301-level puzzle just to schedule a phone screen where they'll ask you to invert a binary tree anyway

    PM: 'Quick spec update.' Figma PNG: LSB-stego'd Cicada 3301. Auditors love it

    In engineering, “quick test” apparently means write an LSB extractor, recover the payload, verify it with PGP, and explain why JPEG was a terrible stego container - good luck, 3301

    The recruiter promised 'just FizzBuzz,' but question one is: extract the PGP block from the image's LSBs, follow the onion link, and then justify the CAP trade-offs of your decoding pipeline

    easy peasy

    1. @sambord 1y

      explain plz

      1. @JackOhSheetImSorry 1y

        You can find info about Cicada 3301 on the internet. It's a series of anonymous-posted cryptography problems, where a solution of one leads to the next one. It happened in the 2000s I guess

        Open the image in a hex editor you will see the text hidden inside (literally)

        1. _ 1y

          Looks like the image got compressed, how do you get the original ?

          1. @mohamed_023 1y

            It's on the internet, this thing has been around since 2012 I think

          2. @Broken_Cloud_1 1y

            Go search cicada 3301

  9. @ZgGPuo8dZef58K6hxxGVj3Z2 1y

    Cidia? Or whatever it was called?

    1. @viktorrozenko 1y

      Cicada

      1. @ZgGPuo8dZef58K6hxxGVj3Z2 1y

        Yes that thing
