Inject shared libraries into running processes

pyinjector's Issues

Have appropriate exceptions for different return values from `injector_attach`

This is already done for permission errors.

How to use?

(I'm on Linux)Whenever I type in pid as an existing process name, and path_to_so_file as an existing dll path, it says syntax error for the pid part. What am I doing wrong?

[Enhancement/Question] inject into Wine processes on Linux

As the title goes, is there any way to inject a DLL into a wine process (running on a Linux system)?

Use the new uninject API in kubo/injector

This is desired anyway, and might allow us to ditch .so copies in hypno

Help please

im getting a No Access error even when running it as administrator, and if i try to compile it to have my friend test it so see if its just a me issue it wont compile properly

Verify injector ABI in tests or compile directly using Python-C API

Return DLL Handle

Is it possible to get the handle of the injected dll?

Failure to inject on Mac

You may get this when trying to inject on Mac: pyinjector.api.MacUnknownInjectorError: injector_attach returned -1: TASK_FOR_PID error : (os/kern) failure
This should be resolved by rerunning as root. Please comment here if it doesn't solved the issue or if you need to be able to run without root. Please state how you installed pyinjector.

Build wheels for Mac

To distribute wheels for mac, we'll need to code-sign the compiled shared libraries. This requires opening a paid apple developer account, which to date costs $100 annually. Currently I do not have such an account, so I will work on this issue once I reach a monthly sponsorship of $8.

Could not find libc

Using pyinjector 1.0.5 with madbg 1.2.0, I get:

attempting to attach to a Python program. This is on Linux 5.15.8.

undefined symbol: injector_attach

System is Debian GNU/Linux 10 (buster) running Python 3.7.3

Installed debugger as

apt install  --no-install-recommends python3-pip python3-setuptools python3-wheel python3-dev build-essential
python3 -m pip install madbg

I have this trace trying to attach:

Question!

Hey I was wondering how strong this system really is? Can it inject into 64 bit processes for example? How stable is the api? Thank you for your answer and I can completly understand if you don't want to answer. :D

add support on > 3.10

Injections fail, Love the project but like to see an injection on 3.10 >

Impossible to compile with PyInstaller or Py2Exe

Hello,

I have been using your library and this is great work, but I am having an issue when trying to run my program once it's compiled to a Windows executable.

It compiles without errors with PyInstaller but this is what I get when I run it :

C:\Users\razen\PycharmProjects\RAT\dist>main.exe
Traceback (most recent call last):
  File "main.py", line 1, in <module>
  File "<frozen importlib._bootstrap>", line 1007, in _find_and_load
  File "<frozen importlib._bootstrap>", line 986, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 680, in _load_unlocked
  File "PyInstaller\loader\pyimod03_importers.py", line 495, in exec_module
  File "pyinjector\__init__.py", line 1, in <module>
  File "<frozen importlib._bootstrap>", line 1007, in _find_and_load
  File "<frozen importlib._bootstrap>", line 986, in _find_and_load_unlocked
  File "<frozen importlib._bootstrap>", line 680, in _load_unlocked
  File "PyInstaller\loader\pyimod03_importers.py", line 495, in exec_module
  File "pyinjector\pyinjector.py", line 6, in <module>
AttributeError: 'NoneType' object has no attribute 'origin'
[12032] Failed to execute script 'main' due to unhandled exception!

This is what I get when running the executable from Py2Exe :

C:\Users\razen\PycharmProjects\RAT\dist>main.exe
Traceback (most recent call last):
  File "main.py", line 1, in <module>
  File "<frozen zipimport>", line 259, in load_module
  File "pyinjector\__init__.pyc", line 1, in <module>
  File "<frozen zipimport>", line 259, in load_module
  File "pyinjector\pyinjector.pyc", line 6, in <module>
  File "importlib\util.pyc", line 90, in find_spec
  File "importlib\util.pyc", line 32, in resolve_name
ImportError: no package specified for '.libinjector' (required for relative module names)

This one goes further and it seems like it is an import issue.

I read somewhere that those compilers can only import libraries using the "import" command.

I also see that you import ".libinjector" another way :

libinjector_path = find_spec('.libinjector', __package__).origin

And this is probably what's causing the issue.

Is there any possible fix ?

Thanks !

How do you use this

i need a example

Add support for windows
