I used the same tool than PeterS, found the link in the wikipedia article to the Vigenere cipher.
It was quite impressing to me that it can be decrypted *that* fast, I knew that it was possible but always thought it involves some bruteforcing which could take a bit of a time.

Thanks to a question in the challenges forum I was pointed back to chess. I was thinking about that but threw away the idea because of wrong field names like 61 or 42. Is this coding of G and H a standard or is it just for confusion? :-) Of course you do write the normal letters G and H in every ch...

It's indeed not easy to find a proper chess database which has a powerful search engine by moves and one that includes all games. However, when creating this challenge I thought at least of two ways which can lead to success anyway: 1. First, search for the chess opening that was played in the game ...

I never knew hacker.org had a virtual machine page? o.O http://www.hacker.org/hvm/ Uhm... yes, and now? I have to disappoint you when you think you've discovered something special or secret, that's just a language used for solving some of the challenges. This thread is really quite senseless but ma...

that's seriously strange, how can a function from the PHP core be missing Since stripos() is only available from PHP 5 I guess adum (or the provider of the webspace) has changed back to an older version. Would be nice if that could be fixed! In the meantime I try to improve my internet security ski...

@gfoot: Oh, you're right, thanks for the hint with the other thread (I should use the search function before posting in future :o ) - after reading the discussion I'm pretty sure now that my algorithm *does* flood correctly, but it simply takes too many cycles. Well, time to start happy optimizing :D

After trying any username and password combination and submitting I get this: I guess this is a bug? Or is this indeed part of the challenge?

Hi folks, I'm just trying around the Flash Flood challenges which are very interesting, but it seems kind of strange for me that the error message "failed to flood correctly" _always_ appears, even when the real reason is exceeding the cycle limit. My code definitely floods correctly becau...

Well, I'm glad the site is back again, my apprehensions were that the bad guy destroyed the database and there were never made any backups of hacker.org. Anyway, I noticed the system for the HVM challenges seems to be broken since the evil 0wnage: Parse error: syntax error, unexpected T_STRING, expe...

Probably the slowest solution ever (took a few hours to compute), pure brute-force approach without any optimization in python: #!/usr/bin/env python fd = open("pimillion", "r") pi = fd.readline() fd.close() for seqlen in xrange(1, 500001): print "len: ", seqlen for ind...

Hello, I didn't write any converter. I simply used convert (part of ImageMagick) to convert the file into raw format: $ convert listen.png listen.rgb $ file listen.rgb listen.rgb: MPEG ADTS, layer III, v2, 32 kBits, 22.05 kHz, Monaural Ah, very nice. I tried that too but I didn't know the file exte...

Thank you for posting that link, I will enjoy reading it.

By the way is anyone here who is actually using any BSD OS?

That was a nice challenge - what did you try first? I approached a bitwise (or should I say pixelwise in this case) OR which worked immediately. However the solution was not very readable in white. Did a XOR combination maybe lead to success too? @osterlaus: Hm, now I'm curious. What are you studyin...

I'm glad we've been able to come to a conclusion on this. And yes, when I said I am majoring in Security, I meant I am currently studying it. This being the case, I will agree that neither of us knows what were talking about in the whole scheme of things. :lol: It was a good discussion though. Full...

Why do you double post?
I guess this thread should be deleted...
