PInjector

Readme-EN - Readme-ES

What is it?

PInjection is a Python script that can be used as a Module or as an executable script from the command line (CLI script). What this script does is inject Object Code into a specific memory region of a process using the Windows API (OpenProcess, VirtuallAllocEx, WriteProcessMemory and ReadProcessMemory.

What is NOT!

• PInjection IT IS NOT an executable script to get your virus to run and break your friend's computer when they go to the bathroom.
• PInjection IT IS NOT an executable script to save executable functions or machine code to a specific memory region.

What YES it is!

• PInjection IS an executable script to put specific marshalized Code Object (CodeType) or marshalized Function Object (FunctionType)within a specific memory region.
• PInjection IS a module that provides an easy-to-use interface for any newbie to Python.
• PInjection IS a good choice to hide Code Object within a process (Similar to DLL Injection).
• PInjection IS a "software libre" project. (GNU GPLv3).

Limitations.

As I said, this is not a script to execute and you will automatically destroy the target computer permanently, but a script/module to load object code in the memory of a process, this means explicitly what I said. To execute the object code that is saved, you have to know what it is, since then you will have to pass a FunctionType using the library types, and there you will have to define all the constants used in the object code. The loading of the object code is automatic, the execution is NOT. There are also many processes in which you will not be able to inject, since these processes have and/or present specific internal conditions that do not allow access to their memory regions

Examples.

---

Injecting the test_function function from the testmodule file into the explorer.exe process (explorer.exe PID 5600).
Command: python pinjection.py 5600 --function testmodule___test_function --verbose Injecting bytecode into explorer.exe

Executing the function once inyected (It is in the memory, at the base address 14548992) Command: python pinjection.py 5600 --constants constantsfile --baseaddr 14548992 --buffsize 164 --execute --verbose Executing bytecode from explorer.exe memory

0.7 notes

• First binary release, this one should be used in a CLI environment, and the python file as a package or module.
