QUESTION
Since 2 day i try to read docs of pymem and search an error on forums but all solution i've seen failed
I can't just read the int in the memory address and i don't know if it's a probleme of code or my pc
...ANSWER
Answered 2022-Apr-09 at 13:14I wonder why you add the return value from pm.readint()
with your offset. It seems that base
is a valid address you can access, while addr + some offset
isn't.
I read from the documentation that read_int reads 4 byte from an area of memory in a specified process. Is the return value addr
the address you want to use?
FYI, I found that the error code is thrown by kernel32, and it means ERROR_PARTIAL_COPY.
QUESTION
ANSWER
Answered 2021-Oct-13 at 01:13I was getting it all wrong from the start. The pointer offsets showed in Cheat Engine are hex values, so the offsets should be offsets=[0x40, 0x464, 0x38, 0x58, 0x18]
.
QUESTION
I'm testing a scenario that when C++ set a function pointer to a python class variable, and then use PyObject_CallMethod to run another python method, which contain that class variable.
whole process would like this.
(1). PyCFunction_NewEx()
make a py function -> (2). PyDict_SetItemString()
assign to class variable under __dict__
-> (3). PyObject_CallMethod()
call python method witch contain (1).
When I put all the code inside main()
function (whitout void setCallback()
and all code inside void setCallback()
were placed in main()
), It runs perfectly fine. However, after I put some code into a function, sometimes get seg fault, sometimes doesn't call function pointer in python and sometimes get correct answer.
How do I resolve this problem?
C++ Code: main.cpp
...ANSWER
Answered 2020-Sep-18 at 05:30It could be because the PyMethodDef
is created on the stack of the setCallback
You can verify it in the source code of cpython here.
the PyMethodDef
is not copied, it is referenced instead.

QUESTION
begin TLDR;
I want to write a python3 script to scan through the memory of a running windows process and find strings.
end TLDR;
This is for a CTF binary. It's a typical Windows x86 PE file. The goal is simply to get a flag from the processes memory as it runs. This is easy with ProcessHacker you can search through the strings in the memory of the running application and find the flag with a regex. Now because I'm a masochistic geek I strive to script out solutions for CTFs (for everything really). Specifically I want to use python3, C# is also an option but would really like to keep all of the solution scripts in python.
Thought this would be a very simple task. You know... pip install some library written by someone that's already solved the problem and use it. Couldn't find anything that would let me do what I need for this task. Here are the libraries I tried out already.
ctypes - This was the first one I used, specifically ReadProcessMemory. Kept getting 299 errors which was because the buffer I was passing in was larger than that section of memory so I made a recursive function that would catch that exception, divide the buffer length by 2 until it got something THEN would read one byte at a time until it hit a 299 error. May have been on the right track there but I wasn't able to get the flag. I WAS able to find the flag only if I knew the exact address of the flag (which I'd get from process hacker). I may make a separate question on SO to address that, this one is really just me asking the community if something already exists before diving into this.
pymem - A nice wrapper for ctypes but had the same issues as above.
winappdbg - python2.x only. I don't want to use python 2.x.
haystack - Looks like this depends on winappdbg which depends on python 2.x.
angr - This is a possibility, Only scratched the surface with it so far. Looks complicated and it's on the to learn list but don't want to dive into something right now that's not going to solve the issue.
volatility - Looks like this is meant for working with full RAM dumps not for hooking into currently running processes and reading the memory.
My plan at the moment is to dive a bit more into angr to see if that will work, go back to pymem/ctypes and try more things. If all else fails ProcessHacker IS opensource. I'm not fluent in C so it'll take time to figure out how they're doing it. Really hoping there's some python3 library I'm missing or maybe I'm going about this the wrong way.

Install pymem
You can use pymem like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
