I have no access to a good computer so it is impossible to crack a hash in a reasonable amount of time. Thanks in advance. Also, post what dictionary you used and which program.
hash1: 2B74D47199B354D472437CCB57040A21FACB72CF4B5B0AF4
hash2: 003AA2321FE6379EF15DB450CA50D8A3FA735E92631EFD66
Thanks!,

Salted? Where is salt then? And what algorithm? |

I believe the algorithm to be SHA-1
They are from Mac OSX 10.4.11 and were extracted using MacKrack
Does that help at all?
Also, I thought the salt was the first 6 digits but IDK for sure. ![Confused](modules/Forums/images/smiles/icon_confused.gif) |

Excuse my pun
I imagine the passwords being between 7 and 10 but they could probably be anywhere from 5 to 12. |

Would online SHA-1 rainbow table be put to any use or not
in Sha-1 salt algorithm, isn't the format SALTPASSWORD
so if your password was qwerty with a salt of 12345 wouldn't it be hashed Sha1 as 12345qwerty and if you took off the salt of the front of the hash you could search it in a rainbow table and if the rainbow table had 12345qwerty could you find it?
I ramble. ![Rolling Eyes](modules/Forums/images/smiles/icon_rolleyes.gif) |

In case of MacOSX SHA-1 salted hashes you can't use traditional rainbow tables, because salt is 4 bytes of binary data. Chances are, that all four bytes of salt are alpha or alphanumeric or something like that, but in most cases those 4 bytes are containing non-traditional characters. For example, in one of your salts there is binary zero. So in other words you can't find downloadable rainbow tables with such charset (all 256 char variations) and building them yourself is not helping either, because they will be too big and performance too poor.
Only real choices are bruteforce and wordlist methods. I tried all my wordlists and some limited bruteforce and got no success. If the password is strong enough, then it's very hard to crack or it can be virtually uncrackable in case of very good password ... |

Well, well, well...what do we have here? It seems Apollo wants to extract the root pass for our iBooks! Heh heh searching the pass on Google automatically came to this thread, seems like waraxe has a pretty good PageRank.
I've been following this thread for a couple days now Apollo...seems you've gotten just as far as me.
I've found the exact same hash hidden in var/db/shadow/hash/<guid>
Code: | 2B74D47199B354D472437CCB57040A21FACB72CF4B5B0AF4 |
I'm trying to compile John the Ripper thru single-user mode, but apparently the -make command doesn't exist.
Anyway, I've tested around 200 wordlists with macKrack all with no results. Trying the brute force method just freezes my box.
Btw, the salted hash should be this:
Code: | root:2B74D47199B354D472437CCB57040A21FACB72CF4B5B0AF4 |
If I'm not mistaken.
Thanks for the help...um also another thing there is a way to reset the administrator password thru single-user mode, but extracting the hash is much more discreet. Resetting the password is easily noticeable lol if one of the admin's attempts to login. |
