  • Publication number: 20240411877
    Abstract: Various aspects related to methods, systems, and computer readable media for detection and blocking of security threats for network-accessible devices. Methods may include receiving an indication of a security threat to a user device of the plurality of user devices, the indication of security threat associated with a device threat type, determining that the device threat type is a threat type that requires elevated security measures, responsive to the determining that the device threat type requires elevated security measures, elevating security measures associated with the user device for a first time period, and, after the elevating, automatically remediating the security threat on the user device within the first time period.

  • Publication number: 20240414176
    Abstract: Various aspects related to methods, systems, and computer readable media for detection and blocking of security threats for network-accessible devices. Methods can include monitoring network traffic on a computer network, detecting an indication of a security threat to at least one endpoint, determining that the device threat type is a threat type that requires elevated security measures, responsive to the determining that the device threat type requires elevated security measures, updating a network-access policy for the plurality of endpoints with the threat type, and after the updating, automatically remediating the security threat on the at least one endpoint within a first time period.

  • Publication number: 20240411878
    Abstract: Various aspects related to methods, systems, and computer readable media for detection and blocking of security threats for network-accessible devices. Methods may include monitoring a plurality of processes executing on the user device to identify a pre-execution flag associated with at least one process of the plurality of processes, and, responsive to identifying the pre-execution flag: receiving an indication of a security threat to the user device, the indication of security threat associated with the at least one process and a device threat type, responsive to the receiving the indication of the security threat, elevating security measures associated with the user device for a first time period, and after the elevating, automatically remediating the security threat on the user device within the first time period.

  • Publication number: 20230247048
    Abstract: Malware detections are received from a plurality of endpoints in one or more enterprise networks. A first and second set of indicators of breach may be identified from the malware detections and, where appropriate, grouped by specific customers. The pattern of progressive deployment of malware directed toward a customer can then be used as a basis for identifying generalized targeting of the customer, or extended staging for a specific attack on the customer such as a ransomware attack.

  • Patent number: 10986109
    Abstract: A technique for local proxy detection includes monitoring outbound traffic from the endpoint with remote network addresses outside the enterprise network, detecting use of a secure communication protocol with a request from the endpoint to one of the remote network addresses, identifying a plaintext network address within the request, and in response to identifying a plaintext network address in the request, initiating remediation of a potentially malicious local proxy on the endpoint.

  • Patent number: 10841339
    Abstract: Threat detection instrumentation is simplified by providing and updating labels for computing objects in a context-sensitive manner. This may include simple labeling schemes to distinguish between objects, e.g., trusted/untrusted processes or corporate/private data. This may also include more granular labeling schemes such as a three-tiered scheme that identifies a category (e.g., financial, e-mail, game), static threat detection attributes (e.g., signatures, hashes, API calls), and explicit identification (e.g., what a file or process calls itself). By tracking such data for various computing objects and correlating these labels to malware occurrences, rules can be written for distribution to endpoints to facilitate threat detection based on, e.g., interactions of labeled objects, changes to object labels, and so forth.

  • Publication number: 20170310693
    Abstract: Protocol suites such as hypertext transfer protocol (HTTP) using secure socket layer (SSL) can facilitate secure network communications. When using this type of secure communication, network addresses are typically expressed as numeric internet protocol addresses rather than the human-readable uniform resource locators (URLs) that are entered into a browser address bar by a human user. This property can be exploited to differentiate between secure and insecure communications, and to detect certain instances where a malicious proxy has been deployed to intercept network traffic with an endpoint.
