Test your skill! Its the third hackathon and so its designed EASY and based on HACKATHON #1 (https://bitcointalk.org/index.php?topic=998907.0) and HACKATHON #2(https://bitcointalk.org/index.php?topic=1005740.0)! THIS TIME ITS LITTLE BIT MORE DIFFICULT, BUT NOT TOO HARD.






if you have any question about this Hackathon #3, ask in this thread or look back in HACKATHON #1 & #2. i can give some hints.



more infos: https://bitcointalk.org/index.php?topic=993678

Can you give some hints for level 4?

Hints for level 3? :(

the hint is in the level3 heading...

HINT from IRC #satoshihack:




look inside of it...

good luck everyone

Anyone got past level 4?

Ok, I got to the end, which it 'spy-250.png'.. However, my search pointed me to an article??  ??? ???
Am I missed something here?

dude i cant even get past 1st level pages are missing

nice lvl 4 :D

lvl 3 was tricky :>


edit: lvl 4 beat me hard tryed uppercase lowercase in many ways... sha1 md5 and the rest...

stuck at lvl 4 :/

You seems to give tips on easy ones >< and hard one let the brain burn..


already 3 hours and nothing >< is imposible to tell a true story


ps: " look inside of it...  " inside of what... Alaska ? :) ( or... i like relaxing )

Edit: aaa.... now must find the language

I am adding another 5000MUE to the winner. Good Luck!

lvl4 hardest... I had more than 100 tryes and nothing... I think lvl 4 is the end for normal people ><

Came back online.

At level 1 now. :)

Edit: Level 2

Edit: Level 3

Stuck :(

Wow! That was tricky!!

Edit: Level 4

Edit: Level 5

what the... lvl 5 Oo damn 4... stuck

So, do you have any idea for Level 5? Have been stuck there for 7 hours there....

Damn language on lvl 4 >< what alien language can be ><

I want to catch lvl 5 until someone finish it >< but can't lol

Level 4 is easy. you will figure it out soon.

Level 5 is really tough! Can't even figure out how to proceed to next level.  :-\

I try to figure it out at lvl 4 since wake up ~4 hours ago.... every try I do is a " lie " ... I can't even calculate how many tryes I did

Lvl 4 kill my brain........... it's hardest lvl from all 3 hackathon's .... so I don't have any chance to win lol...

yes lvl5 is tricky one this time. but when its solved you willl think "ohh its soo logic!". :)




look back to hackathon #1 and #2. you miss something VERY simple...

Hmm.... the picture is related?

EDIT: Does we need to find an answer to solve this, or there is next level?

I have 7 pages opened +4 from here...... ofcorse I have hackathon 1&2 opened ><


Everything tryed... tryed with: 1 ; true ; truth ; AGAIN ;

And from previous just 4 are closely and already tryed some hour ago...
md5("true") = "b326b5062b2f0e69046810717534cb09"
md5(1) = "c4ca4238a0b923820dcc509a6f75849b"
"6B86B273FF34FCE19D6B804EFF5A3F5747ADA4EAA22F1D49C01E52DDB7875B4B" = sha256(1)
"5FFE533B830F08A0326348A9160AFAFC8ADA44DB" //sha1(true)








no tips no nothing..... it's so annoying

I think I won't see lvl 5 until someone win the prize...

Ok, but where do I enter the guesses? I mean in the url?

Pretty challenging one. :)

Edit: Am I supposed to use something like /?login=

Does it need a url parameter? Because, if yes, then what is the variable?

So you are at level 5 too?

Well, since about 12 hours ago...

if you used above values, with all hashin algo from your last post, then you will solve it because one value will fit... so you miss something, or maybe typo??

Edit: miss *censored*


I'm too at 5 :-?

but.. what we search ? a privkey or just something like " matrix "  ; and instinct say me we have to find a page and also tell me to go to first page

<piCube> Hmm... I recognize that the picture its not from your site, therefore I begin reverse search on the image can reached an article from the same domain entitled "Government seeks a warrant to hack" - US judge gives his decision.. The image is just red-herring?
<ca333> yes image is only irritiation..

hmm what's IRC

PS: any chance to be this the last lvl and the pass = "" ; ? I mean no next lvl  ?


Edit2: Keep digging

*nothing usefull*

That Darude-Sandstorm on that source haha  :D :D

IRC = chat. http://webchat.freenode.net/   come in channel: #satoshihack
but i write all hint from IRC in this thread. so you can also ask question in this thread.



no.



 :D  good for "hacking".

3 level done  :)

What is this?  :o :o

I believe its actually Google analytic data collection?

now I try to search everything I can... I think is a answer from " past "

lol :D

I am pretty sure that is the wrong way. It must be simple and obvious (after solving the problem of course).

I got a few things. Simply don't how to connect it.

Who knows? Just in case:

WRONG_HAHAHAHAHA ;)

3902ee7e149eb8313a34757e89e21af6_HAHAHAHAHA

hey =)) I found this first

is WRONG...  ;)

#EDIT: i will give one small hint for lvl5 later. for now, think alone. :) or collaboration with other participants. you can also declare team (with members) in this thread. and when one of team find final solution, reward and hall of fame is shared for the team-participants.

waiting for the hint


edit: Maybe the answer is in front of urs eyes ? something like

" You don't see the forest because of trees " ?

finally joined this hackathon  ;D ;D. can you please give a hint for level 3? i tried all things.
and i solved the second hackathon. but no chance. for 2 hours now.
please any help is welcome.

lvl5 sucks

how long you needed to reach 5? i am stuck in 3. can you give little hint maybe because you solved it already.

about 30 minutes.. i created a script for lvl4, it took only 5 minutes :D

for lvl3, check the second hackathon, they are almost same.

How do you play this? I can't even pass Level 1!

wow 30 minutes is very fast.  :o
okay thank you. i will try this one first with second hackathon.  :)


look in the sourcecode.

Is Level 5 releated to Edward Snowden? x-NSA ;D

I tried every single hash of TRUE, true and 1.
Nothing. Level 4 is impossible.

If you really tried, you should get into level 5.

no you have not because there is soo many algos = soo many hash... lvl4 is possible..
only think little.

-but you are on right path..


HINT for lvl5: "Only when you are from NSA, you can enter lvl6..."

cryptoanarchist333

CONGRATULATION! you win the hackathon INJUST. please post your BTC-adress here. i send you then reward.

It was a real fun hackathon this time, looking forward to the next one!

Congratz, Injust :P
You got lucky this time. ;)
There's will never next time for you >:D xD

Thanks :) Hope you learned never to post hashes in public before you're done solving em. xD
Thanks for all the help.

lol, came back online for another round and gone! :)
Congratz to injust :D

Can someone share the lvl5 answer? (leave lvl 6 in suspense ;))

dd4e53f3cc4577c15953e232720be5a2e9fd22d7c1ae9b80b2af9ce269a5a022
sent the reward. CONGRATULATION AGAIN!

hacking is many factors. Not only technical. also social factors are very important when you see this hackathon...  ;)  and you won because you combine ALL factors you need to solve a hackathon. GOOD JOB!



SOLUTION:

lvl1: "   " (3 x space)
lvl2: 15a755ba37adfc28bc6795b524071618d71096dc6a6b5df091f0947dcc74e0b0 = gost(true)
lvl3: 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa  = pubkey(genesisblock)
lvl4: 8513c69d070a008df008aef8624ed24afc81b170d242faf5fafe853d4fe9bf8aa7badfb0fd045d7 b350b19fbf8ef6b2a51f17a07a1f6819abc9ba5ce43324244 = whirlpool(1)
lvl5: you must change your http-referer. i.e. "curl --referer" or addons for firefox, chrome, etc. (i.e. ModifyHeaders, and my other plugins can make this). so you change referer and make it: 'https://www.nsa.gov' - then you are in lvl6 page.
lvl6: in level 6 you get this string: ad4cd704d846b46dec9f8fb4d8c92ed4333 = md5(cryptoanarchist)+'333' = cryptoanarchist333


thank you all for join the hackathon! hope it was lot of fun! see you next weekend!
ca333

I felt lvl 6 was easier than level 5 lol.

I didn't quite get the changing header part. I don't have a technical background. Just pure logic. an someone explain that?

I will try Googling it.

piCube got first the hash...

I decrypted to cryptoanarchist

and Injust added the 333 =)))


=> Was a team work :))

It certainly says solved by Injust...
Anyway, level 6 is pretty easy If I get that string it is over ;) .

I don't really get the lvl 5 part...

Who cracked lvl 5? (I think Injust did that)

Here's the entire backstory. I couldn't, for the life of me, get past level 4. I know, I'm dumb ::)
So when ca333 posted the "Only when you are from NSA, you can enter lvl6..." hint, I immediately thought of HTTP referers, even though I hadn't made it past level 4 yet.
So I asked piCube to test it, setting the HTTP referer to NSA's website. And it worked. Because according to the HTTP referer, you're are going to the site "from" the NSA.
So piCube practically gave me the answer for level 4, and while I was getting an extension to change HTTP referers, piCube posted the hash that you get in level 6.
I put the hash through CrackStation, gave a partial match. I compared md5(cryptoanarchist) with the hash, found that the only thing different was the 333 at the end, so the answer was cryptoanarchist333.

piCube and Injust noticed referer-manipulation and are ONLY who reach lvl6. Injust provided complete decrypted code first. biCube posted md5-hash in IRC first. But like old hackathons it only count who post the FULL solution. We (me and injust) gave advice to piCube so to not post hashs from the hackathon public before its not solved fully.

Explaining Level 5:
Level 5 check your HTTP-Header. the lvl5 look for your "HTTP-REFERER". this is php object from SERVER-Data array what your client send in the http-packet. So now my lvl5-site look for your referer information. In example when you look many otherside check your referer data for marketing, log, statistics, .... Also advertisin-company (web advertisement banners, links,...) check the referer.. Now you must "fake" the referer and write data into this element. Here its the URL of NSA-website. you can in example make this with "curl". This is a commandline tool you can write
now curl loads the data from http://www.thesiteyouwantTHEDATAFRom.com/ and when this site check the referer in your client information then it gets http://www.thesiteyouCOMEFROM.com. So the site think you COME FROM http://www.thesiteyouCOMEFROM.com. And in level5 the site let you then enter level 6 automatical.

other option: you can also use browser-plugins for header-manipulation and modification. this exist for many web-browser. i.e. mozilla firefox, google chrome you can google and you find lot of web-debug addons. So you can change the http-referer also here.

Thanks :)

I am looking for a chrome extension now.. I tried to read it up from stackoverflow. I understand the concept. Only don't know how to change it.

Thanks for posting all that information. :D

lol, you lucky guy. :P
Next time I get a hash I will keep it a secret. ;)

I have received the 5000 MUE from upgradeadvice.
Thanks!

Wow! Glad everyone had fun - I somehow COMPLETELY forgot, and missed it all! lol!  :-\

same here. I even had a reminder on my phone but didn't manage to get up before it was solved. :(  well, lets make sure we ll join the next one. seems a pretty funny challange. Congratz to the winner btw.

gratulation for the winner! i was stuck in level 3 and when i solved it the hackathon is already hacked. but it was awesome! very nice. next time i try it again.
maybe one day i reach last level. :)

damn i have lost two hackatons since the last, i was absent :(, and i notice that injust its very advanced in this area :( congratulations man you rocks again!

Is there going to be any more of these upcoming, or have I missed something?

no you have not missed it. more will come. i had a problem in RL so i am not able to do it. (https://bitcointalk.org/index.php?topic=993678.msg11061995#msg11061995)

the #4 hackathon is in preparation for the next days.
thank you!
ca333

Same issues here. Don't bother. Launch it after 3 weeks, or so, when I get more time.  ;D

Ah, I see. Speedy healing to you! Looking forward to it when you are able.  ;)

:) prepare and make yourself ready for this weekend.


thank you! i have finished it and will publish the hackathon the coming weekend. The countdown on the site is now accurate.

Great! Looking forward to it!
