First Claim

1. A method, comprising:
- extracting a set of accessed domain names from a set of events stored in a field-searchable data store, wherein each accessed domain name in the set of accessed domain names was not detected in events generated prior to generation of the set of events;
identifying a respective registration time for each accessed domain name in the set of accessed domain names, wherein the respective registration time is indicative of when the accessed domain name was first detected within the set of events;
identifying a subset of accessed domain names in the set of accessed domain names for which the identified respective registration time of each accessed domain name in the subset is recent relative to times for other accessed domain names in the set of accessed domain names;
determining, for each accessed domain name in the subset, an access count corresponding to how many times the set of events indicates that the accessed domain name in the subset was accessed;
causing display of information relating to the access count;
wherein the method is performed by one or more computing devices.

Abstract
Domain names are determined for each computational event in a set, each event detailing requests or posts of webpages. A number of events or accesses associated with each domain name within a time period is determined. A registrar is further queried to determine when the domain name was registered. An object is generated that includes a representation of the access count and an age since registration for each domain names. A client can interact with the object to explore representations of domain names associated with high access counts and recent registrations. Upon determining that a given domain name is suspicious, a rule can be generated to block access to the domain name.

13. An apparatus, comprising:
-
a subsystem, implemented at least partially by hardware, that extracts a set of accessed domain names from a set of events stored in a field-searchable data store, wherein each accessed domain name in the set of accessed domain names was not detected in events generated prior to generation of the set of events; a subsystem, implemented at least partially by hardware, that identifies a respective registration time for each accessed domain name in the set of accessed domain names, wherein the respective registration time is indicative of when the accessed domain name was first detected within the set of events; a subsystem, implemented at least partially by hardware, that identifies a subset of accessed domain names in the set of accessed domain names for which the identified respective registration time of each accessed domain name in the subset is recent relative to times for other accessed domain names in the set of accessed domain names; a subsystem, implemented at least partially by hardware, that determines, for each accessed domain name in the subset, an access count corresponding to how many times the set of events indicates that the accessed domain name in the subset was accessed; a subsystem, implemented at least partially by hardware, that causes display of information relating to the access count. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. One or more non-transitory storage media storing instructions which, when executed by one or more computing devices, cause:
-
extracting a set of accessed domain names from a set of events stored in a field-searchable data store, wherein each accessed domain name in the set of accessed domain names was not detected in events generated prior to generation of the set of events; identifying a respective registration time for each accessed domain name in the set of accessed domain names, wherein the respective registration time is indicative of when the accessed domain name was first detected within the set of events; identifying a subset of accessed domain names in the set of accessed domain names for which the identified respective registration time of each accessed domain name in the subset is recent relative to times for other accessed domain names in the set of accessed domain names; determining, for each accessed domain name in the subset, an access count corresponding to how many times the set of events indicates that the accessed domain name in the subset was accessed; causing display of information relating to the access count. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
