Well I have been using an exploit for SMF forums. It has revealed Hashes, but I have no idea what type of hash it is. It seems a bit long for just a plain MD5 hash so I am thinking there is more too it. I have tried to run it in PasswordsPro without any luck, but I am not even sure I entered it correctly. Can anyone help by telling me what type of hash I have and possibly cracking it. Any information would be helpful thanks!

C:\perl\perl\bin>perl smf.pl -p -u Admin -t http://www.****.net/forum

Finding Password Hash for the Name: 'Admin'

Here are the other hashes that came up under various usernames.

Oh I just finished reading the rest of the script and it is saying,
| Quote: |
The password hash is generated as:
sha1(strtolower() . );
|
Sadly I have no idea what that means, but I have a feeling its the answer.[/quote] |

I read the script and it exactly says:
sha1(strtolower($username) . $password);
In passwordspro there is such a scheme. It's indicated as
sha1($username.$password);
you have to set the user as the lower char conversion of the username you want to crack. |

I can't seem to get any passwords. I even registered on a vulnerable forums and used the password 'password' just as a control and I wasn't even able to crack the hash that came with my account. If anyone has time could they please run these through for me.
Here is supposedly the format, sha1($username.$password);
username : hash
sam : 10f4665ee1de517dd38b8a7202d8b0e8036996ed
amanda : 1a9e202de331d17648eb07ffbe08443732582d08
linds : 1be24e792005794a996b642346bfdc7c1cec0949
Aus10 : 1b9e3bd58439e46cbf2c64167adf52bbb107b0f6
Lauren : 1160bc92c9aaea04aba1fd3c929dd6d4a8ed142b
If anyone could try these I would greatly appreciate it. |

| Just looked more carefully at the screenshot and you put admin as the user name but you used the hash of another user.. Which are the two versions of SMF you attacked? |

I'm not 100% sure about your reply. The version I am trying to attack is SMF 1.1.3 and I am using http://www.milw0rm.com/exploits/4547. Here is basically step by step of what I did;
Run the exploit
Add the username and hash to PasswordsPro
Run PasswordsPro
Obviously I just started running PasswordsPro so I have a while until its done, but this is exactly what I did before to figure out a different hash without any luck. Should I enter the hash into the Salted box? I really have no idea and am willing to try anything. I am also new to PasswordsPro and have noticed at the bottom while its trying to crack the hash it has a box for Current password: that is constantly changing. I assume this is the current password its trying to match with the hash, but what I have noticed is the password displayed is always in capital letters is that a problem? |

You are using a Brute Force Attack, so you checking all the possible passwords in the key space generated by the character set of your choice and the desired range. Try first a dictionary attack? Do you have a good word list?
Btw, I'm going to test some of these with my wordlist. |

Thanks for the advice you truly are the man. I didn't have a very large wordlist, but just downloaded a 2 GB wordlist no idea how good it is. |
