Topic: WIN 5000 EAC. FIRST EARTHCOIN WEBSITE GAMES! (Read 1354 times)

nice games, keep up the good work

Two words (so not so easy for a dictionary attack), but only 9 invisible letters - 26 times easier than the previous one for bruteforcing. Can be bruteforced letter by letter with single 7970 card in about 2 hours (9x[a-z] = 26^9 combinations = 5429503678976 combinations, with hash rate 685000000 hashes/sec - but possibly more, since plain sha256 will take less time than bitcoin hash, since that one uses two chained sha256's). With dictionary and proper card - mere seconds, probably, to crack the password. You need much longer words (at least 20 hidden characters in 2 or 3 words), or change the scheme (not publishing the hash to make it so easy to verify if the password is correct?)

Basically, you need to think how many combinations someone needs to try to get to the password. Anything less than 10^10 is easily crackable. Anything less than 10^13 is still crackable, though it may be more profitable to use the computing power to mine some coins.

With the new hangman, I loooked into english dictionary. There are 694 words matching the first one (anabo ... vnern) and 6147 words matching the second (aaliis .. zygous). This is just 4266018 combinations - checkable within few seconds on CPU, within few milliseconds on a GPU.

Ok, I checked all combinations from "anabo aaliis" to "vnern zygous" and found nothing matching the hash, but I guess it is just a matter of time before someone with better dictionary or more dictionaries (Spanish, French?) finds the answer without needing any more letters.

Fix it.

Also, changed the hanged man to Two words game.

Uhmmm... "Hints pot balance" is 2500... but i didn't see the new image

Well, checking 5000 words whether they match a published SHA256 sum is matter of seconds (if you have good dictionary with these words):

I tried on my machine:
$openssl speed sha256
Doing sha256 for 3s on 16 size blocks: 7327569 sha256's in 3.00s

(so its more like 2500000 checks per second. Could be more if I'd use more threads, or I'd use some GPU sha256 cracker. Not sure if the bitcoin ASIC's can be used to crack plain sha256, but if yes, then with 400 GH/sec someone can go by bruteforcing it letter by letter, going from aaaaaaaaaas to zzzzzzzzzzs in only 6 minutes! - last letter was visible to be "S")

So if the password is a plain word in English or any other reasonable language, someone will guess it in less than a minute.

There are tons of good wordlists on the net, see for example at http://wordlist.sourceforge.net/ - but on other sites there are many many wordlists, some of them meant for password cracking (those contains also commonly used gibberish words like "qwerty" and "123456"), some for spell checking (openoffice has spell-checking wordlists for almost all languages spoken on earth)

I guess I'd download bunch of them to have a chance on next one ... anybody knows about a good GPU sha256 cracker?

The pirate is much more difficult for bruteforcing like that - it consists of "2 to 3 words", possibly with capitalization and as it is either a person's or place's name, it is much less likely to be found in some dictionary. So that probably is same from bruteforcing like that, although if someone gets quite close to the solution by thinking (like somehow narrowing to a list of 1000 possible names), trying them all is matter of few milliseconds

You need to have more difficult solutions (like guessing a 20 characters phrase with hangman), otherwise I bet someone will guess the next one quickly again.

Im mad... Who can guess one 11 letters word with only having the final? There are more than 5.000 words with 11 letters just in english... So the one who won, its someone with a bot full of words and use it to get the mental private wallets.

Uhmmm... if somebody won, why the hanged man is still here? it must change new one.

And, who won... should wrote which was the password? (now has 0 balance the wallet)

Well, I guess someone already won the first one and cashed the reward. No idea what happened to the other two, but last time I checked they were broken (no passworded wallet to download at all ...)

This is what I see when clicking the link to blockchain in the popup with hangman wallet:

Balance: 0 EAC
Transactions in: 1
Received: 1000 EAC
Transactions out: 1
Sent: 1000 EAC

I see only one Hanged man... someone won the other two?

now that's better

you need to give more hints for the hangman

Cause im unloading all and working in the web, not a bug.

There's clearly something wrong with the hanged man games as all the hashes are equals to the hash of the pirate game, or is the pirate game that has something wrong

If you fell like this information helped you fix something.... EAC: 1JNeLXZL8h9xXZ4z4M5atZ5TGNF1nefhiJ

Update: Now the first hangman hash changed to a different one, but the bottom two still have the same hash as the pirate

Ehmmm... is possible to know if the password contains "spacebar" or Uppercase?

Thanks

The game 2 "hanged man" is working but no able cause im working in the web.

Win money with the Pirat Treasura? Im giving 3 hints (clues) for free (the fist picture and the Pirat and Parrot by clicking they... With only 1500 EAC you get 6 hints and you dont have to pay it alone, the people pay if they want (you can win without put a single EAC). Im risking 5000 EAC giving 3 hints for free, and supuse the people pay till 7 surely they are gonna guess the password and i lose 1500 EAC...

Downloading a Wallet from a trusted user... No? But the people download the shit coins clients with troyan without check its...

Do not forget to donate me for my extremely very many wonderful advice.
P.S. 2 games are not working.

New games!!

No - you cannot. You also cannot guess from 1 hint. The author made it so that the one who is opening the last hint (number 8 or for the "most clever guys" number 7) is taking the bank. Until some of the previous openers keep waiting and then all those will begin the rush. As I have mentioned - it is good for author to earn some cash, but there must be something to catch people's attention on. For example simple chain: the greediest loose it all - the bet goes to author. Or logical (erudition) contest - that will be more interesting but valuable only with support from sponsors. Etc. Now it is too raw - nobody will play.

pay 10000EAC to get a hint so that you can win 5000EAC
