Patent number: 11893096Abstract: Systems and methods are described herein for computer user authentication using machine learning. Authentication for a user is initiated based on an identification confidence score of the user. The identification confidence score is based on one or more characteristics of the user. Using a machine learning model for the user, user activity of the user is monitored for anomalous activity to generate first data. Based on the monitoring, differences between the first data and historical utilization data for the user determine whether the user's utilization of the one or more resources is anomalous. When the user's utilization of the one or more resource is anomalous, the user's access to the one or more resource is removed.Type: GrantFiled: December 2, 2021Date of Patent: February 6, 2024Assignee: Cylance Inc.Inventors: Garret Florian Grajek, Jeffrey Lo, Michael Thomas Wojnowicz, Dinh Huu Nguyen, Michael Alan Slawinski

Patent number: 11637858Abstract: Features are extracted from an artifact so that a vector can be populated. The vector is then inputted into an anomaly detection model comprising a deep generative model to generate a first score. The first score can characterize the artifact as being malicious or benign to access, execute, or continue to execute. In addition, the vector is inputted into a machine learning-based classification model to generate a second score. The second score can also characterize the artifact as being malicious or benign to access, execute, or continue to execute. The second score is then modified based on the first score to result in a final score. The final score can then be provided to a consuming application or process. Related apparatus, systems, techniques and articles are also described.Type: GrantFiled: May 29, 2020Date of Patent: April 25, 2023Assignee: Cylance Inc.Inventor: Michael Thomas Wojnowicz

Patent number: 11544358Abstract: Bayesian continuous user authentication can be obtained by receiving observed behavior data that collectively characterizes interaction of an active user with at least one computing device or software application. A sequence of events within the observed behavior data can be identified and scored using a universal background model that generates first scores that characterize an extent to which each event or history of events is anomalous for a particular population of users. Further, the events are scored using a user model that generates second scores that characterizes an extent to which each event or history of events is anomalous for the particular user who owns the account. The first scores and the second scores are smoothed using a smoothing function. A probability that the active user is the account owner associated with the user model is determined based on the smoothed first scores and the smoothed second scores.Type: GrantFiled: October 30, 2020Date of Patent: January 3, 2023Assignee: Cylance Inc.Inventors: Michael Thomas Wojnowicz, Dinh Huu Nguyen, Alexander Wolfe Kohn

Patent number: 11283818Abstract: A system is provided for training a machine learning model to detect malicious container files. The system may include at least one processor and at least one memory. The memory may include program code which when executed by the at least one processor provides operations including: processing a container file with a trained machine learning model, wherein the trained machine learning is trained to determine a classification for the container file indicative of whether the container file includes at least one file rendering the container file malicious; and providing, as an output by the trained machine learning model, an indication of whether the container file includes the at least one file rendering the container file malicious. Related methods and articles of manufacture, including computer program products, are also disclosed.Type: GrantFiled: April 28, 2020Date of Patent: March 22, 2022Assignee: Cylance Inc.Inventors: Xuan Zhao, Matthew Wolff, John Brock, Brian Michael Wallace, Andy Wortman, Jian Luan, Mahdi Azarafrooz, Andrew Davis, Michael Thomas Wojnowicz, Derek A.
