HackerPit: challenge your inner hacker
- danbruc 13y agoWhy sign in with twitter? I have no twitter account so they lost me.
- Ecco 13y agoHi, author here. Restricting login to Twitter was initially an experiment. Turns out it's also very convenient for people who are on Twitter, as you signup in a single click! And since this website is far from being important for anyone, I thought it made more sense to lose a few users here and there rather than forcing everyone through the tedious tunnel of picking an email, picking a password, checking your email, etc… Still I'm really sorry to have lost you. Good job on getting to level 2 though!
- zombio 13y agoLevel 2? The sign in button is on the first page.
- Ecco 13y agoI assumed he was on level 2 as you can play the first level without signing up.
- danbruc 13y agoMaybe you could offer no tracking or tracking by cookies or something like a password after each puzzle as an alternative.
- fps 13y agoAfter your hint above, it took me 30 seconds to hit level 2, but now I fear I'm left out of the fun because I'm on linux, so no mac app store.
- Ecco 13y agoA Mac is not needed :)
- zombio 13y agoViewed source, found hint. When I get home I'm going to try searching for all colours that aren't FFFFFF or 000000. The file name looks like a code.
- darxius 13y agoI definitely see shapes when I back up and focus in the middle of the picture. Reminds me of those awesome hidden picture games as a kid. I swear I saw Santa.
- Ecco 13y agoDon't get yourself a pink eye tough! Hint: I'd be very surprised if you could see "it" with your naked eyes. You'd better fire up your favorite image editor ;-)
- deleted 13y ago[deleted]
- darxius 13y agoNice, I got the first one. This is fun.
- Ecco 13y agoThanks!
- swordsmith 13y agoThis is actually pretty fun. Although my first reaction to the "white noise" hint was to pull up matlab and do a 2D-fft, figured it might show a picture. Would never have thought contrast/brightness though :(
- k3liutZu 13y agoDid that for 30 minutes. Sau a flower, pikatchu, a leaf, and a half avocado.
- tobeportable 13y agoreminds me of : http://www.ouverture-facile.com/riddles/ http://www.ouverture-facile.com/riddles/
- Ecco 13y agoOuverture facile definitely was an inspiration. This is more developper/hacker oriented though.
- k3liutZu 13y agoRemembering why I don't like OAuth
- Ecco 13y agoWell, it's more to do with white box crypto ;-)
- jroblak 13y agoThe hint in the source is a little strange...it's not really a hint at all.
- adlpz 13y agoWell... it is a hint. It does look like that, but it isn't.
- jackmaney 13y agoYou need to change "In this picture, I see _____" to "In this picture, I think you see ____". I see nothing but static, and have never been able to see the images in those old-fashioned "3D" pictures. Thus, when I say "In this picture, I see static", that is absolutely correct. Why should I waste another second on your page after you've pulled such a bait-and-switch? What does the page have to do with hacking?
- josephndenton 13y agoPull the image into Photoshop and do some tweaking with levels.
- danbruc 13y agoSpoiler: This has nothing to do with stereograms [1] - looking at steganography [2] will be much more helpful.

- shawabawa3 13y agoIt's not a 3D picture. There's a code hidden in the image. I found it by opening in gimp and randomly messing with colours/brightness/levels/etc Level 2 appears to require that I download iTunes to reverse engineer an itunes twitter app... I gave up on that
- ryanSrich 13y ago+ Drag image to desktop + Open photoshop + Reduce brightness 2-4 times + Punch in code + Get to level 2 + Give up
- Ecco 13y agoWhy? Level 2 isn't good?
- shawabawa3 13y agoAs far as I can tell, you're supposed to download iTunes on mac and reverse engineer the oauth secret key from the twitter app. I just got it by googling twitter oauth key leaks... Definitely wasn't a fun or interesting challenge.
- zfran 13y agoGot to level 2 and gave up on the Twitter app one, since I'm running Linux and I don't have an Apple computer handy.
- Ecco 13y agoIndeed, but that's not the only way to solve this level!
- lotsofcows 13y agoIt didn't like "polar bear in a snow storm" so I had play with an image editor and then gave up because of the Twitter requirement.
- Ecco 13y agoReally? Is requiring Twitter that bad? I thought it was a convenient way for most people to signup!
- shawabawa3 13y agoYou know what's a convenient way for people to sign up? Having them enter an email/password. What are you gaining from Twitter authentication? What are users gaining from it?
- lotsofcows 13y agoIf you use Twitter, I'm sure it's very easy. If you don't it's a new learning curve of unknown length / gradient.
- dpcx 13y agoI got to level 3. Then there's talk of writing code about Rainman, and now I'm fully stumped.
- shawabawa3 13y agoWell... either you can do image processing to count the number of blobs...or do a vague count, get a ballpark figure and brute force it
- Ecco 13y agoIndeed! Again, that's part of the game. The server is having a bit of a hard time though, as you weren't the only one having this idea :-)
- Ecco 13y agoLevel 3 is already impressive! The Rainman thing is a joke though ;-)
- xvolter 13y agoI got to level 4 by writing a simple script bruteforce method, tried every number from 1 to 100+ until I got the right answer. Don't want to give out the answer, but yes, the answer was more than 100.
- aeurielesn 13y agoI can't why this application will need all these permissions: + Read Tweets from your timeline. + See who you follow. Why's that? Are these standard twitter permissions?
- Ecco 13y agoUnless you have locked your account (missing the whole point of Twitter IMHO) this is public information… And yes, this is just the default settings :-)
- eranation 13y agoHm... nice, but I managed to get to level 4 with just using some Google fu (for #2) and the online http://pixlr.com http://pixlr.com (was lazy enough to download GIMP). And I didn't need to write a line of code so far (yep, not even for #3, took me 5 minutes manually). Is that the intention?
- xvolter 13y agoI hope that it gets harder, but so far it doesn't appear it will.
- xvolter 13y agoI feel like level 4 doesn't take http://www.mjt.me.uk/posts/falsehoods-programmers-believe-about-addresses/ http://www.mjt.me.uk/posts/falsehoods-programmers-believe-ab... into account. Also, the question on level 4, "The only gramatically correct address in that file is", grammatically is spelled incorrectly. Since it wouldn't make a good hint, I assume it's a typo.
- abhshkdz 13y agoLevel 4 hint: Streets: 1. rue du Temple 2. boulevard Montmartre 3. boulevard du Temple 4. impasse du chat 5. rue des blancs-manteaux 6. avenue des champs-elysees
