Abstract: The disclosed computer-implemented method for location-restricting one-time passcodes may include (1) receiving, from a client, an authentication request for a user account, (2) receiving, in association with the authentication request, a one-time passcode that incorporates an originating location for the authentication request, (3) obtaining a location identifier indicating the location of the client, (4) determining that the location identifier indicates a location equivalent to the originating location, and (5) determining, at least in part in response to determining that the location identifier indicates a location equivalent to the originating location, to authenticate the client to the user account. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A computer-implemented method for generating tripwire files may include (1) generating an initial tripwire file according to an initial tripwire generation calculation, the initial tripwire file configured such that modification of the initial tripwire file triggers investigation of a security breach, (2) generating a subsequent tripwire file according to a subsequent tripwire generation calculation, the subsequent tripwire generation calculation differing from the initial tripwire generation calculation along at least one dimension, (3) receiving automated feedback that indicates whether at least one of the initial tripwire file and the subsequent tripwire file failed to enable detection of a security threat, and (4) adjusting automatic generation of a third tripwire file based on the automated feedback indicating whether at least one of the initial tripwire file and the subsequent tripwire file failed to detect the security threat.

Abstract: A computer-implemented method for modifying file backups in response to detecting potential ransomware may include (1) detecting, during a file backup process, an anomaly that is potentially indicative of ransomware on a computing device, (2) in response to detecting the anomaly that is potentially indicative of ransomware, storing a backup copy in a separate location from other backup copies, (3) confirming that the anomaly is indicative of ransomware on the computing device, (4) adjusting a backup policy in response to confirming that the anomaly is indicative of ransomware on the computing device, and (5) managing the backup copy based on the adjusted backup policy. Various other methods, systems, and computer-readable media are also disclosed.
