A technique shares smart television data among subscribing organizations to provide security. The technique involves collecting, by an electronic server apparatus, data elements from multiple smart television devices. The technique further involves performing, by the electronic server apparatus, a set of risk analysis operations to generate risk scores corresponding to the multiple smart television devices. Each risk score (e.g., a numerical value) indicates an amount of risk (e.g., a probability) that a respective smart television device is malicious. The technique further involves providing, by the electronic server apparatus, an ordered list of the multiple smart television devices, the ordered list ranking the multiple television devices based on the risk scores. Information from the ordered list is well suited for use by an anti-fraud service in which subscriber organizations are informed of the information and use the information to identify and stop fraudulent activity in the future.
