System and method are disclosed to protect a voice-activated assistant against accidental or malicious activation. The system includes a device interacting with the cloud having an assistive device, which in turn is protected by another, protective assistant. The protective assistant detects incoming malicious (or spurious) actions triggered by a third party which tries to connect to the device through the assistant. The protective assistant then emits a signal that would perturb the third party signal, or prepares and issues “cancellation” commands to automatically cancel the action. The system may also notify the user via SMS / phone call / email / screen notification to further manually check the legitimacy of the detected malicious action. User experience is improved as accidental or unintended orders will not be executed by their assistants.
