News : OneByteRadar - pymem python package.

Today, I found this GitHub project about how to write to exe files with python programming language

The author say:

CS:GO radar hack achieved by patching one byte of game memory. Written in Python 3.

I don't test it, but good to know how can use these python modules.

The pymem Python library that allows you to interact with the memory of running Windows processes.

• Reading and writing memory values of other processes
• Scanning memory for byte patterns
• Allocating and freeing memory inside another process
• Accessing modules (DLLs) loaded by a process
• This is often used in game hacking, automation, or debugging tools.

NOTE: I used artificial intelligence to write this simple example, it is more productive in programs with more complex syntax, but the basics of programming must be known...

Let's see one example with edge browser open:

import pymem
import pymem.process
import re

# Open the Edge process (make sure it's running)
pm = pymem.Pymem("msedge.exe")

# Get the main module of the process
module = pymem.process.module_from_name(pm.process_handle, "msedge.exe")
base = module.lpBaseOfDll
size = module.SizeOfImage

# Read the module's memory
data = pm.read_bytes(base, size)

# Search for a test pattern (generic example)
pattern = re.search(rb'\x48\x89\x5C\x24\x08\x57\x48\x83', data)

if pattern:
    address = base + pattern.start()
    print(f"Pattern found at: {hex(address)}")

    # Read 8 bytes from the found address
    raw = pm.read_bytes(address, 8)
    print("Raw bytes:", raw)

    # Interpret the bytes as a little-endian integer
    value = int.from_bytes(raw, byteorder='little')
    print("Integer value:", value)

    # Write a new value (e.g., 12345678)
    new_value = (12345678).to_bytes(8, byteorder='little')
    pm.write_bytes(address, new_value, 8)
    print("Value overwritten with 12345678.")

else:
    print("Pattern not found.")

# Close the process handle
pm.close_process()

What is that patern:

pattern = re.search(rb'\x48\x89\x5C\x24\x08\x57\x48\x83', data)

These bytes correspond to x86-64 assembly instructions. For example:

48 89 5C 24 08 → mov [rsp+8], rbx
57 → push rdi
48 83 → the start of an instruction like add/sub/cmp with a 64-bit operand

This sequence is typical for the prologue of a function in compiled C++ code — saving registers to the stack.

This is a simple example, you don't see anything in edge because is just one search and one overwritten:

python pymem_exemple_002.py
Pattern found at: 0x7ff7180cb3d5
Raw bytes: b'H\x89\\$\x08WH\x83'
Integer value: 9459906709773125960
Value overwritten with 12345678.

You replaced those 8 bytes with the integer 12345678, encoded as: 4E 61 BC 00 00 00 00 00 (in hex)

This corrupts the original instruction, which may crash Edge or cause undefined behavior.

Not crash, maybe my edge browser use protections (ASLR, DEP, CFG) that can make modification unstable.

1. ASLR (Address Space Layout Randomization)

2. DEP (Data Execution Prevention)

3. CFG (Control Flow Guard)

Python Qt6 : tool for remove duplicate files ...

Today I created a Python script with PyQt6 that allows me to remove duplicate files based on three ways of selecting the type of duplicate.

The script also makes an estimate of the execution time...

Because the source code is relatively simple and can be very easily reconstructed with the help of artificial intelligence, I am not adding it to the posts.

Here is what the application looks like with PyQt6.

Blender 3D : ... simple clothing addon.

Today, I created a simple clothing addon with a two-mesh coat. The addon adds everything needed for the simulation including material types for the clothes.

Python Qt6 : tool for cutting images ...

Today I made a script that allows adding custom horizontal and vertical sliders to an image and, depending on the custom distance between them, cuts the image into squares of different sizes.

Python Qt6 : tool for renaming files with creation date .

Since this hacking and the crashes... I've always taken screenshots... Today I created a small script that takes files from a folder and renames them with the creation date in this format...yyyyMMdd_HHmmss .

... obviously artificial intelligence helped me.

This is the source code :

import sys
import os
import shutil
from PyQt6.QtWidgets import QApplication, QWidget, QPushButton, QVBoxLayout, QFileDialog, QMessageBox
from PyQt6.QtCore import QDateTime

class FileRenamer(QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("Redenumire fișiere cu dată și index")
        self.setGeometry(100, 100, 400, 150)

        layout = QVBoxLayout()

        self.button = QPushButton("Selectează folderul și redenumește fișierele")
        self.button.clicked.connect(self.rename_files)
        layout.addWidget(self.button)

        self.setLayout(layout)

    def rename_files(self):
        folder = QFileDialog.getExistingDirectory(self, "Selectează folderul")
        if not folder:
            return

        files = [f for f in os.listdir(folder) if os.path.isfile(os.path.join(folder, f))]
        files.sort()  # Sortează pentru consistență

        for index, filename in enumerate(files, start=1):
            old_path = os.path.join(folder, filename)
            try:
                creation_time = os.path.getctime(old_path)
                dt = QDateTime.fromSecsSinceEpoch(int(creation_time))
                date_str = dt.toString("yyyyMMdd_HHmmss")
                ext = os.path.splitext(filename)[1]
                new_name = f"{date_str}_{index:03d}{ext}"
                new_path = os.path.join(folder, new_name)

                # Evită suprascrierea fișierelor existente
                if not os.path.exists(new_path):
                    shutil.move(old_path, new_path)
            except Exception as e:
                QMessageBox.critical(self, "Eroare", f"Eroare la fișierul {filename}:\n{str(e)}")
                continue

        QMessageBox.information(self, "Succes", "Fișierele au fost redenumite cu succes!")

Python 3.13.0 : Script for python modules then installs them - updated with fix.

This script scans a folder full of .py files Python scripts, identifies all the external modules they import, filters out built-in ones, writes the installable ones to a requirements.txt file, and then installs them using pip—in parallel threads for speed.

I use the copilot and some comments are into my language, but I tested and works well:

NOTE: I updated with detection python modules based "from" and another issue: check if python module is instaled and step over that python module ...

This script will try to install many python modules, I can update to be better with these issues:

...some modules are default , some scripts are from another area, see Blender 3D with bpy python modules, some packages comes with same modules, this can be soleved with defined lists with unique items.

Python Qt6 : Use python with ffmpeg tool ...

If you download a video from youtube with high resolution using a tool as yt-dlp then you can get two files with video and audio content:

... one with be with .f401.mp4 and another with .f251-9.webm and using the ffmpeg tool you can create one .mp4 file with both audio and video content.

Let's see a source code with python and PyQt6 module to search into D:\Software folder and create the mp4 file.

News : Django Hijack

Log in and work on behalf of other users without having to know their credentials.

With Django Hijack, admins can impersonate and work on behalf of other users without having to know their credentials.

Comes with two versions available: v2.x and v3.x. The last v3.x provides a security first design, easy integration, customisation, out-of-the-box Django admin support and dark-mode. It is a complete rewrite and all former APIs are broken.

Python Qt6 : simple celtic knots tool with SVG file format.

Today, I try to create SVG file with an celtic knot design tool.

I used random values from -360 up to 360 for for Twist 1, Twist 2, and Twist 3 sliders.

The basic function is this, is created by artificial intelligence and not works very well.

        # Generate star polygon vertices
        points_cw = []
        points_ccw = []
        for i in range(steps):
            t = 2 * math.pi * i / steps
            r = outer_radius if i % 2 == 0 else inner_radius
            x_cw = center[0] + r * math.cos(t)
            y_cw = center[1] + r * math.sin(t)
            x_ccw = center[0] + r * math.cos(-t + math.pi / max(lobes, 1))
            y_ccw = center[1] + r * math.sin(-t + math.pi / max(lobes, 1))
            points_cw.append((x_cw, y_cw))
            points_ccw.append((x_ccw, y_ccw))

See one random example with this tool:
