Abstract

A method for detecting a cyber-attack by performing a first analysis on content within a first portion of a communication to determine whether the content includes a first high quality indicator. The first high quality indicator identifies a correlation of the content with a malicious activity. Subsequent to the first analysis, performing a second analysis on a second portion of the communication to determine one or more supplemental indicators. Thereafter, the communication is classified as part of a cyber-attack when (i) a value associated with the first high quality indicator exceeds a first threshold without consideration of the one or more supplemental indicators, or (ii) upon failing to exceed the first threshold and being greater than a second threshold, using the values representing the one or more supplemental indicators with the first value to classify the communication as being part of the cyber-attack.
