Domain Reputation Evaluation Process and Method

摘要

A system for the identification and subsequent rating of domains based on a result derived from a proprietary algorithm configured to detect when a new domain is registered, correlate the domain to registrant data, cross-check the data based on domain proximity to known-malignity, and output a proximity score employed to convey the potential for malicious content or intentions available or to be served as content accessible via the domain. The system is equipped with a dynamic domain database configured to provide near-real-time domain registration data across all domain extensions, facilitating the detection and scoring of new domains as soon as practicable after their inception. Domains are routinely re-evaluated for score consistency, helping to better maintain the security of visitors to websites hosted, or automated connections to infrastructure present on the domain.

1. A method for identifying malicious domains on a computer comprising:
the computer executing a DNS crawl of all known domains on the internet augmented by passive DNS data; the computer extracting nameserver host names from the DNS data; the computer retrieving email addresses from Whois data; the computer retrieving registrant names from Whois data; the computer identifying which registrant names have a large variation of registration emails through the use of parsed Whois data; the computer excluding registrant names with a large variation of registration emails from input data; the computer employing blacklist data feeds to filter all domains; the computer flagging domains identified in the data feeds; the computer identifying a type of threat from each suspect domain, including Malware, Spam, Phishing, and infrastructure Botnet; the computer generating a proximity score of each domain, with suspect domains having a high proximity score indicating a high likelihood the suspect domain is malicious; and the computer flagging suspect domains as malicious.
