# Emotet Dropper

In 

# Overview

This folder contains files used to generate an emotet dropper.

The dropper works as follows:

  1. Word document invokes VBA code via AutoOpen

  2. AutoOpen macro downloads "adb.vbs" to %AppData% over 192.168.0.4:8080 / HTTP.

  3. AutoOpen macro executes adb.vbs with cscript.

  4. adb.vbs downloads a second-stage dropper; the dropper is heavily obfuscated.

  5. The second stage VBS code executes base64 encoded PowerShell code.

  6. The PowerShell code downloads EmotetClientDLL.dll over 192.168.0.4:443 / HTTPS and writes to disk at %AppData%\adb.dll

  7. The PowerShell code executes adb.dll via rundll32.exe and Control_RunDLL function

# Quick Start

Upload ChristmasCard.docx to your intended target.

Open ChristmasCard.docx - it should download/execute the Emotet DLL, and send C2 connections to 192.168.0.4:80 / HTTP.

# Usage

  1. Run this script on Windows to generate an obfuscated VBS payload:
.\generate_emotet_dropper.ps1
  1. Copy obfuscated_emotet_dropper.vbs to the control server at this path:
wizard_spider/Resources/control_server/files/

  1. Now create a new word document

  2. In the word document, go to View > Macros > Record Macro > create a new Macro named AutoOpen and store it the document"

  3. Hit OK and stop the recording under Macros

  4. Go to View > View Macros > Select and edit AutoOpen macro

  5. Paste the source code from vba_macro_code.vbs into the macro

  6. Upload the word document to the intended target.

The payload should fire automatically after opening the document.
