Claim 18:
19. A system comprising:
a processor; and
one or more non-transitory computer-readable storage medium having stored thereon program instructions executable by the processor to cause the system to,
scan the Internet for publicly accessible communication ports with probes having an initial payload, wherein the program instructions to scan the Internet comprise program instructions executable by the processor to cause the system to scan the Internet external to one or more networks corresponding to the publicly accessible communication ports;
for each response,
determine whether the response indicates a network address active on a port and a service associated with the port; and
based on a determination that the response indicates a network address active on a port and a service associated with the port, determine a set of one or more follow-up payloads based, at least in part, on the response and deliver to a device associated with the network address the set of one or more follow-up payloads to interact with the device and request data from the device; and

update a database based, at least in part, on the responses to the probes having the initial payload and responses to the follow-up payloads.
