Abstract: A method for detecting threat pathways using sequence graphs includes constructing a sequence graph from a set of data containing information about activities in a telecommunications service provider network, where the sequence graph represents a subset of the activities that occurs as a sequence, providing an embedding of the sequence graph as input to a machine learning model, wherein the machine learning model has been trained to detect when an input embedding of a sequence graph is likely to indicate a threat activity, determining, based on an output of the machine learning model, whether the subset of the activities is indicative of the threat activity, and initiating a remedial action to mitigate the threat activity.

Abstract: Methods, computer-readable media and devices for calculating fraud scores for pending payment transactions are disclosed. A method includes a processor receiving a request for a fraud score. The request comprises a notification of a pending payment transaction that is associated with a credit card of a user and associated with a first location. The processor then detects a location of a device associated with the user, calculates a fraud score based upon the location of the device and the first location, and sends a response comprising the fraud score that is calculated.
