Abstract: In one embodiment, a computing device collects ransomware behavioral data of known ransomware, the ransomware behavioral data based on one or more file writing features, and trains a ransomware classifier with the ransomware behavioral data to detect ransomware. The computing device may then share the ransomware classifier with a detection device to cause the detection device to behaviorally detect ransomware based on applying the ransomware classifier to monitored file writing activities. In another embodiment, in response to behaviorally detecting ransomware, based on applying the ransomware classifier to monitored file writing activities, the detection device may then perform one or more ransomware mitigation measures in response to behaviorally detecting ransomware.

Abstract: Systems and methods for multi-domain routing are provided. In some embodiments, a method for determining a path calculation from a source node to a destination node over a multi-domain network is provided. The method may include steps for receiving a predetermined sequence of domains for communicating information from the source node to the destination node, determining a link type for each of a plurality of links in the predetermined sequence of domains, modifying the link type of one or more of the plurality of links such that the plurality of links are unidirectional links towards a destination node, and determining a path along the predetermined sequence of domains based on the modified plurality of links.

Abstract: Systems and methods for determining multiple paths in a multi-domain network are provided. In some embodiments, a method for determining multiple paths in a network is provided. The method may include determining a first path between a source node and a destination node and determining a second path disjoint from the first path. In some embodiments, to determine the second path includes determining which ingress nodes are available in a domain that includes the destination node, where the available ingress nodes are not part of the first path, and implementing a disjoint path algorithm for each of the available ingress nodes. To determine the first path includes implementing forward path calculations.
