What is Process Herpaderping ?

Process Herpaderping is a technique used to evade Antivirus solution by modifying the content on disk after the image file has been mapped.

These are the steps to achieve this attack:

• Read the Payload Binary (CreateFile)
• Create the target file on disk, keep the handle open. We will execute it later in memory (CreateFile)
• Map the target file as an image (NtCreateSection)
• Write random data on the target file handle (GetFileSize, SetFilePointer, ...)
• Create the thread of the target file (NtCreateThreadEx)
• Wait for the process to execute ...
• Close the handle

Getting Started

Prerequisite

Clone

Clone the repository, then fetch and update all the submodules

$ git clone https://github.com/Nikj-Fr/Process-Herpaderping.git
$ cd .\Process-Herpaderping
$ git submodule update --init --recursive

Project Setup

Here are all the configuration I made to my Visual Studio project

• Include Folder within Visual Studio must look to find librairies

• Setup the precompiled header file

• List of the project dependencies (.lib to include)

bcrypt.lib
ntdll.lib
kernel32.lib
user32.lib
gdi32.lib
winspool.lib
comdlg32.lib
advapi32.lib
shell32.lib
ole32.lib
oleaut32.lib
uuid.lib
odbc32.lib
odbccp32.lib

• Compiled Architecture As a development infrastructure I used the x64-Debug profile of Visual Studio

Start the executable

# After a sucessfull compilation..
$ cd .\Process-Herpaderping\Herpaderping\x64\Debug
$ Herpaderping.exe [PayloadFile] [TargetFile]
