20230027153 · 2023-01-26 ·

Systems and methods are provided for a detection and defense system relating to a network connection sharing application. For example, the system can simulate a request for a network password using a conventional application that shares this information. The application may be implemented on, for example, a mobile device or a virtual machine (VM). In some embodiments, the mobile device/VM attempts to establish a network connection to an access point (AP) using the shared password over a tunnel established between the AP and mobile device/VM. If the mobile device/VM can connect to the AP, an assumption may be made that the user credentials have been leaked and a potential security risk exists. An alert can be sent to a network administrator of the communication network (e.g., to perform an action, etc.). The action may include, for example, changing the password, removing access from one or more users, and the like.

20170358096 · 2017-12-14 ·

Approaches presented herein enable tracking a physical object with a holographic projection, and, more specifically, enhancing a view of an object by tracking the object with a 3-D holographic projection. A holographic object tracking projection system receives, from a sensor, a feed of an area containing a physical object and locates a position of the physical object in the area based on the feed. The system creates a visible holographic object to mark the physical object, and projects the holographic object, using a holographic projector, at the position of the physical object. The holographic object can be a shape that surrounds the physical object in order to increase a visibility of the physical object. The physical object may move, and, as the physical object moves, the holographic object tracking projection system tracks this movement and adjusts the holographic object to match the movement of the physical object.
