Abstract
Systems and methods are disclosed for identifying domains as malicious based on Internet-wide DNS lookup patterns. Disclosed embodiments look for variance in the servers that look up a domain and also look at the popularity growth (quantity of queries from unique addresses) of a domain after registration to identify malicious domains. Other disclosed embodiments measure the similarity of servers that query a domain and cluster domains based on the similarity of those servers. Disclosed embodiments may use such temporal and spatial lookup patterns as input to a blacklist process to more effectively and quickly blacklist domains based on their Internet-wide lookup patterns.
