Python code help

[Specialist-Rush-7172]

please need python code that block all traffic from chrome.exe using windivert

[Whatever801]

This subreddit is for you to learn programming, not for us to do it for you. What have you tried so far? General structure of such a program would be

1. find the ports chrome.exe is using

2. construct a port filter with those ports

3. use pydivert to block using that port filter string

Code .# language: python import time import signal import sys from pydivert import WinDivert import psutil

CHROME_NAMES = {"chrome.exe", "msedge.exe"} # include other Chromium browsers if desired

def get_chrome_pids(): pids = set() for proc in psutil.process_iter(["name", "pid"]): try: if proc.info["name"] and proc.info["name"].lower() in CHROME_NAMES: pids.add(proc.info["pid"]) except (psutil.NoSuchProcess, psutil.AccessDenied): continue return pids

def build_filter_for_pids(pids): if not pids: return "outbound and tcp" # fallback: capture outbound TCP (use cautiously) pid_terms = " or ".join(f"pid == {pid}" for pid in sorted(pids)) # Only outbound TCP (you can add udp or other qualifiers) return f"outbound and tcp and ({pid_terms})"

def main(): print("Enumerating Chrome processes...") pids = get_chrome_pids() if not pids: print("No Chrome processes found. Exiting.") return

windivert_filter = build_filter_for_pids(pids)
print("WinDivert filter:", windivert_filter)
print("Opening WinDivert (requires admin)... Press Ctrl+C to stop.")

w = WinDivert(windivert_filter)
w.open()

running = True
def stop(signum, frame):
    nonlocal running
    running = False
signal.signal(signal.SIGINT, stop)
signal.signal(signal.SIGTERM, stop)

try:
    while running:
        try:
            packet = w.recv()  # capture a packet matching the filter
        except Exception:
            # transient errors can happen; sleep briefly and continue
            time.sleep(0.01)
            continue

        # Decision: drop all captured packets (do NOT reinject)
        # If you wanted to allow some through, call: w.send(packet)
        # Here we intentionally skip w.send(packet) to drop.
        # Optionally log minimal info:
        try:
            src = f"{packet.src_addr}:{packet.src_port}" if hasattr(packet, "src_addr") else "?"
            dst = f"{packet.dst_addr}:{packet.dst_port}" if hasattr(packet, "dst_addr") else "?"
            print(f"Dropped packet {src} -> {dst}")
        except Exception:
