Abstract
Files uploaded to a cloud storage medium are considered. The files may include a mixture of files known to be malicious and known to be benign. The files are clustered using similarity of file features, e.g., based on distance in a feature space. File clusters may then be used to determine a threat status of an unknown file (a file whose threat status is unknown initially). A feature of the unknown file in the feature space is determined, and a distance in the feature space between the file and a file cluster is calculated. The distance between the unknown file and the file cluster is used to determine whether or not to perform a deep scan on the unknown file. If such a need is identified, and the deep scan indicates the unknown file is malicious, a cybersecurity action is triggered.
