摘要

A server system with processor (s) and memory identifies, among a plurality of messages sent over a social networking platform, a respective message that satisfies a predefined first criterion indicating that the respective message includes a potentially suspicious URL. The server system determines a legitimate URL that corresponds to the potentially suspicious URL based on contextual information corresponding to the respective message. In accordance with a first determination that the legitimate URL and the potentially suspicious URL in the respective message are not identical, the server system determines a level of similarity between the legitimate URL and the potentially suspicious URL. In accordance with a second determination that the level of similarity exceeds a first predetermined threshold, the server system: identifies the potentially suspicious URL in the respective message as a suspicious URL； and performs a security risk determination process on a first website corresponding to the suspicious URL.
