Create a stageless JavaScript payload targeting version 4 of the .NET framework. This example will create a payload named foo.js in the output directory. The shellcode is read from the ./raw.txt file. The payload attempts to enforce some sandbox evasion by keying execution to the CONTOSO domain, and checking for known sandbox/VM artifacts.
Create a stageless HTA payload targeting version 2/3 of the .NET framework. This example will create a payload named foo.hta in the output directory. The shellcode is read from the ./raw.txt file. The payload attempts to enforce some sandbox evasion by checking for known virtual MAC addresses. A HTML smuggling payload will also be generated named foo.html in the output directory. This payload will use the example McAfee virus scan template.
This example creates a staged VBS payload that performs both Web and DNS delivery. The payload will attempt to retrieve a GZipped CSharp file that executes the shellcode supplied as a CSharp byte array in the csharpsc.txt file. The CSharp file used is the built-in SharpShooter shellcode execution template. The payload is created in the output directory named foo.payload and should be hosted on http://www.foo.bar/shellcode.payload. The same file should also be hosted on the bar.foo domain using PowerDNS to serve it. The VBS file will attempt to key execution to the CONTOSO domain and will be embedded in a HTML file using the HTML smuggling technique with the McAfee virus scanned template. The resultant payload is stored in the output directory named foo.html.
This example demonstrates how to create a staged JS payload that performs web delivery, retrieving a payload from http://www.phish.com/implant.payload. The generated payload will attempt sandbox evasion, and attempt to compile the retrieved payload which requires mscorlib.dll and System.Windows.Forms.dll as DLL references. The Main method in the MDSec.SharpShooter namespace will be executed on successful compilation.
This example creates a VBS smuggled COM stager that uses the Outlook.CreateObject() COM method as a primitive to execute wmic.exe to execute a hosted stylesheet. The --awl parameter is not used by defaults to wmic.
This example creates an Excel 4.0 SLK file that executes the supplied shellcode and wraps it in HTML. The shellcode cannot contain null bytes, hint:
msfvenom -p generic/custom PAYLOADFILE=./payload.bin -a x86 --platform windows -e x86/shikata_ga_nai -f raw -o shellcode-encoded.bin -b '\x00'
Ivy
Ivy is a payload creation framework for the execution of arbitrary VBA (macro) source code in memory. Ivy’s loader does this by abusing programmatical access in the VBA object environment to load, decrypt, and execute shellcode.
