Abstract

A system for detecting artifacts associated with a cyber-attack features a cybersecurity intelligence hub remotely located from and communicatively coupled to one or more network devices via a network. The hub includes a data store and retroactive reclassification logic. The data store includes stored meta-information associated with each prior evaluated artifact of a plurality of prior evaluated artifacts. Each meta-information associated with a prior evaluated artifact of the plurality of prior evaluated artifacts includes a verdict classifying the prior evaluated artifact as a malicious classification or a benign classification. The retroactive reclassification logic is configured to analyze the stored meta-information associated with the prior evaluated artifact and either (a) identify whether the verdict associated with the prior evaluated artifact is in conflict with trusted cybersecurity intelligence or (b) identify inconsistent verdicts for the same prior evaluated artifact.
