  • Publication number: 20260113354
    Abstract: Techniques for detecting malware process injection on a host device. The techniques may include receiving endpoint metadata associated with an event, the endpoint metadata including information associated with a process that made a network connection from a host device. The techniques may also include receiving network metadata associated with the event, the network metadata including a network protocol fingerprint used to make the network connection. The techniques may further include determining that the network protocol fingerprint is indicative of a presence of malware process injection via the process running on the host device. Based on detecting the process of the malware process injection, an indication may be reported to a monitoring system and one or more remedial actions may be taken.

  • Publication number: 20250293992
    Abstract: Techniques and mechanisms for identifying unmanaged cloud resources with endpoint and network logs and attributing the identified cloud resources to an entity of an enterprise that owns the cloud resources. The process collects data from sources, e.g., endpoint and network logs, with respect to traffic in a computer network and based at least in part on the data, extracts relationships related to the traffic. The process applies rules to the relationships to extract destinations in the computer network that provide cloud resources in a cloud environment, wherein the cloud resources are owned by an enterprise. One or more users or business entities of the enterprise are identified as accessing the cloud resources.

  • Publication number: 20230357342
    Abstract: The present disclosure relates a modified interleukin 18 (IL-18) polypeptide, methods of making the same, and methods of using the modified IL-18 polypeptides for treatment of diseases including cancer. The modified IL-18 polypeptide can exhibit an ability to induce interferon gamma (IFN?) production when in contact with a cell, exhibit a diminished ability to be inhibited by IL-18 binding protein (IL-18BP) compared to wild type IL-18 (WT IL-18), and exhibit a ratio of half-maximal inhibitory concentration (IC50) by IL-18BP to half-maximal effective concentration (EC50) to induce IFN? production which is greater than that of WT IL-18.

  • Publication number: 20220094529
    Abstract: In one embodiment, an apparatus captures a memory dump of a device in a sandbox environment executing a malware sample. The apparatus identifies a cryptographic key based on a particular data structure in the captured memory dump. The apparatus uses the identified cryptographic key to decrypt encrypted traffic sent by the device. The apparatus labels at least a portion of the decrypted traffic sent by the device as benign. The apparatus trains a machine learning-based traffic classifier based on the at least a portion of the decrypted traffic sent by the device and labeled as benign.

  • Patent number: 7379531
    Abstract: A system uses a digital photographic camera attached to a radiation therapy device to create an overlay of radiation beam information comprising data identifying treated patient anatomical region data and supporting determination of cumulative radiation treatment information from multiple treatment overlays. A system records a treatment beam landing area on the anatomical body surface of a patient for use in radiation or other therapy. The system includes an input processor for receiving data representing an image of the surface of a portion of the anatomy of a patient. A data processor provides beam landing position data relative to the image by calculating a position of a treatment beam landing area relative to the image using received input data indicating projection characteristics of a treatment beam used in treating the portion of the anatomy of the patient. A storage processor stores the beam landing position data in a record associated with the patient.

  • Publication number: 20060242144
    Abstract: A system determines a most recent medical image study accessed or used by a healthcare worker and identifies the most up to date instance of a medical image study stored in a distributed environment with multiple DICOM storage nodes, for example. A medical image data acquisition and processing system, involves multiple sources of medical image data accessible via a network. The medical image data comprises one or more sets of medical images of a particular patient individually including an associated medical image set identifier. A search processor automatically initiates a search of the multiple sources to identify existence of sets of medical images of a particular patient having a duplicate first medical image identifier, in response to a user command to access a set of medical images having the first medical image identifier.
