Python reading process memory

How can I read the memory of another process in Python in Windows?

I’m trying to write a Python script that reads a series of memory locations of a particular process.

How can I do this in Python?

I’ll be using Windows if it matters. I have the processes PID that I’m attempting to read/edit.

Am I going to have to revert to calling ReadProcessMemory() and using ctypes?

I didn’t see anything in the standard python libraries but I found an example using ctypes like you suggested on another site:

from ctypes import * from ctypes.wintypes import * OpenProcess = windll.kernel32.OpenProcess ReadProcessMemory = windll.kernel32.ReadProcessMemory CloseHandle = windll.kernel32.CloseHandle PROCESS_ALL_ACCESS = 0x1F0FFF pid = 4044 # I assume you have this from somewhere. address = 0x1000000 # Likewise; for illustration I'll get the .exe header. buffer = c_char_p("The data goes here") bufferSize = len(buffer.value) bytesRead = c_ulong(0) processHandle = OpenProcess(PROCESS_ALL_ACCESS, False, pid) if ReadProcessMemory(processHandle, address, buffer, bufferSize, byref(bytesRead)): print "Success:", buffer else: print "Failed." CloseHandle(processHandle) 

Yes, ctypes (or win32all ) and ReadProcessMemory are exactly the way to go. Were you looking for something extra/different? What, in particular?

You can use tasklist.exe to list processes, then scrape the results. Then use taskkill.exe (or tstskill.exe) to end them.

But ctypes and kernal32 is probably safer.

ReadWriteMemory

Description

The ReadWriteMemory Class is made on Python for reading and writing to the memory of any process. This Class does not depend on any extra modules and only uses standard Python libraries like ctypes.

Documentation

Requirements

Python 3.4+
OS: Windows 7, 8 and 10

Windows API’s in this module:

Usage

Import and instantiate the Class

To be able to read or write to the process’s memory first you need to call the open() method.

The offsets must be a list in the correct order, if the address does not have any offsets then just pass the address. You need to pass two arguments, first the process address as hex and a list of offsets as hex.

Check out the code inside the Test folder on the python file named testing_script.py. The AssaultCube game used for this test is version v1.1.0.4 If you use a different version then you will have to use CheatEngine to find the memory addresses. https://github.com/assaultcube/AC/releases/tag/v1.1.0.4
