Abstract: Systems and methods for Zero-day Data Loss Protection (DLP) having enhanced file upload processing are provided. One method may include capturing and sending file upload context (e.g. folder name, metadata, an active URL, etc.) associated with the scheduled file or folder upload to a DLP filesystem driver. For example, the method may include detecting whether a single/multi-file upload, a folder upload, or a drag-and-drop operation exists, through interception of the shell dialog API, the browse folder API, or the drop process interface, respectively. Further, the method may include generating a file upload cache including the file upload context, prior classification entries, and a timestamp indicating when the scheduled file or folder upload was last modified; such that, the DLP filesystem driver may intercept and process the file open call based upon the file upload cache. Accordingly, the file may be processed in accordance with a prior file classification, file/domain filter, or DLP policy.

Abstract: A computer-implemented method for data loss prevention of unidentifiable and unsupported object types may include (1) monitoring, through at least one filter, data input to an application during execution, (2) scanning, through a data loss prevention scanner, the data input to the application to detect whether the data includes sensitive data that is protected by a data loss prevention policy, (3) flagging, based on the scanning, the application as having accessed the sensitive data that is protected by the data loss prevention policy, (4) detecting that the application is requesting to output a data object in a format that obscures underlying content, and (5) performing, by a data loss prevention program, a remedial action to prevent loss of the sensitive data based on both flagging the application and detecting that the application is requesting to output the data object in the format that obscures underlying content.
