Leonid Karabchevsky has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240080339
    Abstract: Devices, systems, and methods of detecting a vishing attack, in which an attacker provides to a victim step-by-step over-the-phone instructions that command the victim to log-in to his bank account and to perform a dictated banking transaction. The system monitors transactions, online operations, user interactions, gestures performed via input units, speed and timing of data entry, and user engagement with User Interface elements. The system detects that the operations performed by the victim, follow a pre-defined playbook of a vishing attack.

  • Patent number: 11269977
    Abstract: System and method of collecting and processing data in electronic devices. A sensors data collector collects measurements from at least an accelerometer and a gyroscope of an electronic device. A data-loss prevention module operates to pass these measurements, immediately upon their collection, to a supplemental locally-running processing thread which retains the measurements even after a refresh of a web-page in which the measurements were collected, and which transmits the measurements to a remote server even after refresh of the web-page in which the measurements were collected. Non-global scope of functions is utilized, to reduce security exposure. An asynchronous SharedWorker module is utilized, to alleviate congestion of computing resources of the electronic device. Data obfuscation and encoding is utilized to maintain anonymity of user-entered data while still allowing a remote server to ensure the integrity of data received from the electronic device.

  • Patent number: 10397262
    Abstract: Devices, systems, and methods to detect malware, particularly an overlay malware that generates a fake, always-on-top, masking layer or an overlay component that attempts to steal passwords or other user credentials. A defensive module protects a victim application, particularly of an electronic device having a touch-screen. The defensive module generates a transparent or invisible always-on-top layer of its own; and periodically injects automatically-generated non-human tap events or touch-gesture events, and checks whether the injected events are indeed received, in order to determine whether an overlay malware is active.
