Assignee: PROOFPOINT, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A computing platform, comprising:
at least one processor;
a communication interface communicatively coupled to the at least one processor; and
memory storing computer-readable instructions that, when executed by the at least one processor, cause the computing platform to:
execute one or more machine learning algorithms to compare a first domain to a baseline dataset, wherein executing the one or more machine learning algorithms comprises:
determining feature vectors corresponding to a HyperText Markup Language (HTML) tag structure of one or more pages associated with the first domain,
comparing the feature vectors corresponding to the HTML tag structure to the feature vectors corresponding to known legitimate domains of the baseline dataset, resulting in one or more structure analysis values comprising averages of top-N similarity scores for a plurality of selected N values, and
determining that the one or more structure analysis values exceed one or more predetermined structure analysis threshold values; and

based on execution of the one or more machine learning algorithms, send one or more commands directing a domain identification system to remove the first domain from a list of indeterminate domains maintained by the domain identification system.
