USB Logger is a C++ application designed to monitor USB device insertions on Windows systems. Upon detecting a new USB drive, the program logs the directory structure and identifies suspicious files (such as .exe, .bat, and .scr files). The application runs in the background, ensuring minimal disruption while providing robust monitoring capabilities.

• Real-Time USB Monitoring: Detects when a USB drive is connected to the system.
• Directory Structure Logging: Recursively scans and logs the entire directory structure of the connected USB drive.
• Suspicious File Detection: Identifies and logs potentially malicious files based on their extensions.
• Threaded Operations: Performs scanning in separate threads to maintain application responsiveness.
• Timestamped Logging: All logs are timestamped for accurate tracking.
• Thread-Safe Logging: Ensures logs are written safely in multi-threaded environments.
• Configurable Extensions: Easily modify the list of file extensions considered suspicious.
• Error Handling: Comprehensive error messages and exception handling for robust performance.

• Operating System: Windows 10 or later
• Compiler: Microsoft Visual Studio 2019 or later (with C++ support)
• C++ Standard: C++17 or later

1. Clone the Repository

   git clone https://github.com/texploder/usb-logger.git
   cd usb-logger

2. Open the Project

   Open the usb-logger project in Visual Studio.

3. Build the Project

   • Select the desired build configuration (Debug or Release).
   • Build the solution by pressing Ctrl + Shift + B or navigating to Build > Build Solution.

4. Run the Application

   • After a successful build, navigate to the output directory (e.g., bin/Release).
   • Execute the USBLogger.exe file.

Once the application is running, it operates silently in the background. To test its functionality:

1. Insert a USB Drive:

   • Plug a USB drive into your computer.
   • The application will detect the insertion and begin scanning the drive.

2. Check Logs:

   • Logs are saved in the Structures directory located in the same directory as the executable.
   • Each USB drive will have a unique log file named based on its volume name and serial number, e.g., MyUSB-1A2B3C4D.txt.

3. Review Suspicious Files:

   • Suspicious files are marked with [SUSPICIOUS] in the log file.
   • Additionally, these detections are printed to the console with timestamps.

[2025-01-27 10:15:30] USB Drive detected: E:\
[2025-01-27 10:15:31] Created log file: C:\Path\To\USBLogger\Structures\MyUSB-1A2B3C4D.txt
[2025-01-27 10:15:31] Folder structure saved to C:\Path\To\USBLogger\Structures\MyUSB-1A2B3C4D.txt
    [Folder] Documents
        [File] report.docx
    [Folder] Executables
        [File] setup.exe [SUSPICIOUS]
        [File] installer.bat [SUSPICIOUS]

The application currently flags .exe, .bat, and .scr files as suspicious. To modify this list:

1. Open the main.cpp file in your preferred code editor.

2. Locate the suspicious_extensions vector:

   std::vector<std::string> suspicious_extensions = { ".exe", ".bat", ".scr" };

3. Add or remove extensions as needed:

   std::vector<std::string> suspicious_extensions = { ".exe", ".bat", ".scr", ".dll" };

4. Rebuild the application to apply changes.

By default, logs are saved in a Structures folder within the executable's directory. To change the log directory:

1. Open the main.cpp file.

2. Locate the check_usb_drive function and modify the structures_dir path:

   std::string structures_dir = exe_dir + "\\YourDesiredDirectory";

3. Rebuild the application.

• Logging Mechanism:

  Handles thread-safe logging with timestamps.

  std::mutex log_mutex;
  
  std::string current_timestamp() {
      // Generates current timestamp
  }
  
  void log_message(const std::string& message) {
      std::lock_guard<std::mutex> guard(log_mutex);
      std::cout << "[" << current_timestamp() << "] " << message << std::endl;
  }

• USB Detection:

  Utilizes Windows API to detect USB device insertions.

  LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) {
      if (uMsg == WM_DEVICECHANGE && wParam == DBT_DEVICEARRIVAL) {
          // Handle USB arrival
      }
      return DefWindowProc(hwnd, uMsg, wParam, lParam);
  }

• Directory Scanning:

  Recursively scans USB directories and logs structure and suspicious files.

  void save_tree_and_check_files(const std::string& path, const std::string& output_file, std::vector<std::string> suspicious_extensions, int level = 0) {
      // Recursive directory scanning
  }

• Multithreading:

  Ensures scanning runs in separate threads to maintain responsiveness.

  std::thread usb_thread(check_usb_drive, drive_path);
  usb_thread.detach();
