Collaborative phishing attack detection
Described herein are methods, network devices and machine-readable storage media for detecting whether a message is a phishing attack based on the collective responses from one or more individuals who have received that message. The individuals may flag the message as a possible phishing attack, and/or may provide a numerical ranking indicating the likelihood that the message is a possible phishing attack. As responses from different individuals may have a different degree of reliability, each response from an individual may be weighted with a corresponding trustworthiness level of that individual, in an overall determination as to whether a message is a phishing attack. A trustworthiness level of an individual may indicate a degree to which the response of that individual can be trusted and/or relied upon, and may be determined by how well that individual recognized simulated phishing attacks.
