[HELP] wininet.dll hook

[darkhunter]

Good evening, I wanted to ask if you can create a form-grabber or a hook dll wininet.dll as in the botnet Zeus in vb6, thanks in advance for the answers

[Kulverstukas]

If it was done in Zeus, then it's obvious that you can... but why VB6? why do you have to use that skiddy shit that has been used among skiddy malware devs so much?

[darkhunter]

Unfortunately I only know the vb6 and I could not find a good guide on the C in Italian

Took me forever to find a working Zeus link, however here is the source. It should be somewhat easy to port to VB6. Look under source at corehook, userhook, and httpgrabber; it should get you started.

Thanks for the reply, one last thing, could you tell me if there is a way to make a BTC Mining in vb6?

[vezzy]

Given that VB6 is a Turing complete language, it is by no means impossible, however it is computationally infeasible since Bitcoin mining is a cryptographically demanding and arduous process of calculating SHA-256 block headers. Which is unsuitable for a language like Visual Basic.

[xC]

Calculating hashes is easier in VB6 then traditional C. If you create a module for that alone and use the included components for appropriate handshakes it actually takes far less code.

Edit: I included in the post a VB6 example of SHA-256 encryption. Also, here is a little information about the Bitcoin method.

Thanks for the replies, however I wondered how I could do it in vb6 because unfortunately I do not know C

[xC]

You need no knowledge of C to port something to VB6 except the calls.

Thanks for the answers

of course you can just use the winapi, you will need to declere all needed function first

example:

Code: [Select]

Declare Auto Function MBox Lib "user32.dll" Alias "MessageBox" (
    ByVal hWnd As Integer,
    ByVal txt As String,
    ByVal caption As String,
    ByVal Typ As Integer) As Integer
