A method for automated determination of IP address information of malicious attacks. An intrusion detection system may receive an index tree for storing IP addresses in one or more nodes of the index tree in a predefined sorting order. The instruction detection system may receive a data structure including a first set of one or more IP addresses from a honeypot system. The intrusion detection may receive unstructured data indicative of a second set of one or more IP addresses from a predefined data source. The intrusion detection system may process the unstructured data to determine the second set of one or more IP addresses. The intrusion detection system may insert each IP address of the first and second sets of one or more IP addresses into one or more nodes of the index tree.
