Update neurolyzer.py

Browse Source 
Realistic MAC Address Generation

    Improvement: The updated version uses a more realistic MAC address by incorporating an OUI (Organizationally Unique Identifier) and randomizing the last three bytes within a restricted range.

    Flexible Randomization Interval

    Improvement: The randomization interval is now flexible, varying between 30 minutes and 2 hours. Randomizing the interval adds unpredictability, making the MAC address changes harder to detect. This increases stealth.

    Improved MAC Randomization for Monitor Mode

    Improvement: When the Wi-Fi interface is in monitor mode, the plugin temporarily switches to managed mode to change the MAC address and restores monitor mode afterward.

    Updated UI Handling

    Improvement: The UI is now updated more effectively by directly modifying the value attribute of the UI components in on_ui_update().

    Better Error Handling and Logging

    Improvement: The plugin now has enhanced error handling for subprocess calls, such as bringing the interface down or changing the MAC address. More detailed logs are provided for different stages.

    Initial MAC Address Randomization

    Improvement: The plugin now performs an initial MAC address randomization when it is loaded (self.randomize_mac() in on_loaded()). This ensures that the device's MAC address is randomized as soon as the plugin starts, providing enhanced privacy from the start.

    Time-Dependent MAC Randomization

    Improvement: The next MAC address change time is now dynamically calculated based on the random interval. This ensures the MAC address change schedule follows the random interval, making it harder to predict.
