  • Patent number: 11902299
    Abstract: Methods, systems, and computer storage media for providing a multi-attribute cluster-identifier that supports identifying malicious activity in computing environments. An instance of an activity having an attribute set can be assessed. The attribute set of the instance of the activity is analyzed to determine whether the instance of the activity is a malicious activity. The attribute set of the instance of the activity is compared to a plurality of multi-attribute cluster-identifiers of previous instances of the activity, such that, a determination that the instance of the activity is a malicious activity is made when the attribute set of the instance of the activity corresponds to an identified multi-attribute cluster-identifier. The identified multi-attribute cluster-identifier has a risk score and an attribute set that indicate a likelihood that the instance of the activity is a malicious activity. A visualization that identifies the instance of the activity as a malicious activity is generated.

  • Patent number: 10454866
    Abstract: Embodiments provide IP address partitioning features that can be used to source outbound email communications, but the embodiments are not so limited. In an embodiment, a computer-based method operates to remove blocked or potentially misused IP addresses from a partition and/or move good or reputable IP addresses from other partitions to account for volumetric shortfalls. A method of one embodiment operates to repair removed IP address reputations as part of recycling and reusing IP addresses. A system of an embodiment is configured in part to remove misused IP addresses from one or more partitions, source reputable IP addresses from other partitions, and/or repair and reuse IP addresses as needed. Other embodiments are included.

  • Patent number: 9749271
    Abstract: Embodiments provide IP address partitioning features that can be used to source outbound email communications, but the embodiments are not so limited. In an embodiment, a computer-based method operates to identify and/or isolate one or more customers that may be misusing one or more IP addresses of a partition. A system of an embodiment is configured in part to divide a partition that includes one or more potentially misused IP addresses into one or more levels of sub-partitions as part of identifying offending or potentially offending customers. Other embodiments are included.
