Malicious homoglyphic domain name (MHDN) detection and associated cyber security applications are described. A domain name may be received that may be a potential MHDN. Homoglyphic domain name detection may be performed by, for example, generating a normalized character string corresponding to the input domain name by applying one or more normalization operations to the input domain name, wherein the one or more normalization operations may be configured to reduce homoglyphic characteristics in the input domain name; and generating a plurality of segmentations of the normalized character string, wherein generating each segmentation, of the plurality of segmentations, may comprise segmenting the normalized character string into a respective plurality of segments, and wherein each segmentation may comprise a different plurality of segments. A segmentation may be selected based on cost values corresponding to each respective segmentation determined using a cost function. The received domain name may be determined to be a homoglyphic domain name based on a determination that one or more segments of the selected first segmentation match a base of a known domain name in the at least one list of known domain names.
A computing device for malicious homoglyphic domain name (MHDN) detection, wherein the computing device comprises:
A method for malicious homoglyphic domain name detection, wherein the method comprises:
One or more non-transitory computer-readable media having instructions stored thereon for homoglyphic domain name detection that, when executed by one or more computing devices, cause the computing devices to:
