Abstract
In some embodiments, a set of hashes that are associated with files of a user system, and a reference set of hashes that are associated with files of a reference system, may be obtained. An additional subset of hashes (included in the set of hashes and not included in the reference set of hashes) may be obtained based on a comparison between the set of hashes and the reference set of hashes. A file may be predicted to be exclusive for certain users or user systems, where the file is associated with a hash included in the additional subset of hashes. Other user systems may be scanned to determine what files are on the other user systems, where each of the other user systems is assigned to another user or is not one of the user systems. An alert indicating unauthorized activity may be generated based on the scan.
