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:

EnumProcesses
GetProcessImageFileName
OpenProcess
Process Security and Access Rights
CloseHandle
GetLastError
ReadProcessMemory
WriteProcessMemory

Usage

Import and instantiate the Class

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

Get a Process by name

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

process = rwm.get_process_by_name('ac_client.exe')

Get a Process by ID

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

process = rwm.get_process_by_id(1337)

Get the list of running processes ID's from the current system

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

processes_ids = rwm.enumerate_processes()

Print the Process information

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

process = rwm.get_process_by_name('ac_client.exe')
print(process.__dict__)

Print the Process HELP docs

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

process = rwm.get_process_by_name('ac_client.exe')
help(process)

Exception: ReadWriteMemoryError

from ReadWriteMemory import ReadWriteMemory
from ReadWriteMemory import ReadWriteMemoryError

rwm = ReadWriteMemory()
try:
    process = rwm.get_process_by_name('ac_client.exe')
except ReadWriteMemoryError as error:
    print(error)

Open the Process

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

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

process = rwm.get_process_by_name('ac_client.exe')
process.open()

Set the pointers for example: to get health, ammo and grenades

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.

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

process = rwm.get_process_by_name('ac_client.exe')
process.open()

health_pointer = process.get_pointer(0x004e4dbc, offsets=[0xf4])
ammo_pointer = process.get_pointer(0x004df73c, offsets=[0x378, 0x14, 0x0])
grenade_pointer = process.get_pointer(0x004df73c, offsets=[0x35c, 0x14, 0x0])

Read the values for the health, ammo and grenades from the Process's memory

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

process = rwm.get_process_by_name('ac_client.exe')
process.open()

health_pointer = process.get_pointer(0x004e4dbc, offsets=[0xf4])
ammo_pointer = process.get_pointer(0x004df73c, offsets=[0x378, 0x14, 0x0])
grenade_pointer = process.get_pointer(0x004df73c, offsets=[0x35c, 0x14, 0x0])

health = process.read(health_pointer)
ammo = process.read(ammo_pointer)
grenade = process.read(grenade_pointer)

Print the health, ammo and grenade values

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

process = rwm.get_process_by_name('ac_client.exe')
process.open()

health_pointer = process.get_pointer(0x004e4dbc, offsets=[0xf4])
ammo_pointer = process.get_pointer(0x004df73c, offsets=[0x378, 0x14, 0x0])
grenade_pointer = process.get_pointer(0x004df73c, offsets=[0x35c, 0x14, 0x0])

health = process.read(health_pointer)
ammo = process.read(ammo_pointer)
grenade = process.read(grenade_pointer)

print({'Health': health, 'Ammo': ammo, 'Grenade': grenade})

Write some random values for health, ammo and grenade to the Process's memory

from ReadWriteMemory import ReadWriteMemory
from random import randint

rwm = ReadWriteMemory()

process = rwm.get_process_by_name('ac_client.exe')
process.open()

health_pointer = process.get_pointer(0x004e4dbc, offsets=[0xf4])
ammo_pointer = process.get_pointer(0x004df73c, offsets=[0x378, 0x14, 0x0])
grenade_pointer = process.get_pointer(0x004df73c, offsets=[0x35c, 0x14, 0x0])

process.write(health_pointer, randint(1, 100))
process.write(ammo_pointer, randint(1, 20))
process.write(grenade_pointer, randint(1, 5))

Close the Process's handle when you are done using it.

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

process = rwm.get_process_by_name('ac_client.exe')
process.open()

process.close()

Examples

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

process.write(health_pointer, randint(1, 100))

process.write(grenade_pointer, randint(1, 5))

health = process.read(health_pointer)
ammo = process.read(ammo_pointer)
grenade = process.read(grenade_pointer)

print('\nPrinting the new modified random values.')
print({'Health': health, 'Ammo': ammo, 'Grenade': grenade})

process.close()
