Hello Mates, So to start off you are going to wan't to download a program named "SQLi Dumper".

Link: SQLi Dumper
Decryption Key: Decryption Key
VT: VirusTotal
(Before you go all "OMFG VT SAYS ITS A VIRUS ON 3 RESULTS SO IT MUST BE" Please learn what a False Positive is)

Now that you have SQLi Dumper Please Open it you should see the following screen:

Now where that big Text Box is in the middle is where you need to paste your Dork's you wan't to scan for.
Basic idea of What A Dork is Here.
Here is some Free Dork's.
Now you wan't to click on start scanner (Feel free to adjust the threads depending on your Internet and PC power)
Spoiler (Click to View)

Then when it finishes scanning you should get some "Exploitables" You are going to want to click on "Start Exploiter"

Spoiler (Click to View)

Alright now that you have injectibles you are going to wan't to right click on a Injectable URL and click on "Go To Dumper"

It should now show the Databases for that website
Click on the Database and click on "Get Tables"

Now find a Table that looks like it might have Login info Like "Members" or "Users" etc etc then click on it and click "Get Columns" and if the Columns are named something a long the lines of "Email" and then another column named "pass" you are in luck you are going to wan't to check both of those Columns (Usernames will work for some sites also but it's usually better to have Email:Pass) Then click on "Dump Data".

Now save that Information that is going to be What we call a "Combolist" it is what we are going to run to check if they have a account on the sites we are going to be cracking.

So now you are going to need to download 3 things before we start cracking
SentryMBA: SentryMBA Multi Patched
Password: Password
VT:VirusTotal

Proxies ( I am not going to show how to scape proxys in this Tut but I will link some I have previously scraped)

Proxys: Proxies
Decryption Key: Decryption Key

Now you need a SentryMBA Config I will link some of my Configs:
PM Me if you need a config, I will not be posting those on the thread

Alright so now load your config into SentryMBA, Load your Proxys then load the config you exploited earlier and start cracking ( I recommend to use 100 Bots as a default UNLESS IT IS A PROXYLESS CONFIG THEN USE 7)

That is it for now, I plan to go more into detail but to be honest I am tired of typing for right now.
