.SYNOPSIS
Standalone Powershell script that will generate a malicious Microsoft Office document with a specified payload and persistence method
.DESCRIPTION
This script will generate malicious Microsoft Excel Documents that contain VBA macros. This script will prompt you for your attacking IP
(the one you will receive your shell at), the port you want your shell at, and the name of the document. From there, the script will then
display a menu of different attacks, all with different persistence methods. Once an attack is chosen, it will then prompt you for your payload type
(Only HTTP and HTTPS are supported).
When naming the document, don't include a file extension.
These attacks use Invoke-Shellcode, which was created by Matt Graeber. Follow him on Twitter --> @mattifestation

.Attack Types
Meterpreter Shell with Logon Persistence: This attack delivers a meterpreter shell and then persists in the registry
by creating a hidden .vbs file in C:\Users\Public and then creates a registry key in HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows\Load
that executes the .vbs file on login.
Meterpreter Shell with Powershell Profile Persistence: This attack requires the target user to have admin right but is quite creative. It will
deliver you a shell and then drop a malicious .vbs file in C:\Users\Default\AppData\Roaming\Microsoft\Windows\Cookies\cookie.vbs. Once dropped, it creates
an infected Powershell Profile file in C:\Windows\SysNative\WindowsPowerShell\v1.0\ and then creates a registry key in
HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows\Load that executes Powershell.exe on startup. Since the Powershell profile loads automatically when
Powershell.exe is invoked, your code is executed automatically.
Meterpreter Shell with Alternate Data Stream Persistence: This attack will give you a shell and then persists my creating 2 alternate data streams attached to the AppData
folder. It then creates a registry key that parses the Alternate Data Streams and runs the Base64 encoded payload.
Meterpreter Shell with Scheduled Task Persistence: This attack will give you a shell and then persist by creating a scheduled task with the action set to
the set payload.
