Of these 24, one third were defacements of regional versions of Google. One of these domains was defaced twice on separate occasions 5 years apart. Malware and Spam Distribution 4 In 3 cases, domains were used to distribute exploit kits or other malware. In 1, domains were used to send spam. Financial Gain 4 These attacks included 3 targeting domains related to cryptocurrency, and 1 targeting a bank. Espionage Information Stealing 2 One case targeted a security firm, and the ultimate motivation may have been financ }}} {{{ IV. DNS HIJACKING DETECTION VII. CONCLUSIONS In this work we extensively studied the characteristics of DNS hijacking attacks and explored the detection of such attacks from the position of a party defending a local network from attacks originating outside the network, including off- path spoofing, MITM, and domain hijacking attacks. We analyze previous studies or reports of known attacks. Based on measurements related to these, we derived a set of features that might be used to identify unusual changes in a domain’s DNS that require further inspection or blocking. We tested our approach on a large passive DNS dataset containing several million records collected for a period of over 10 years. The results of validation and testing have a low FPR, consistently less than 1%. Examining feature importance highlights the importance of focusing on nameserver changes, suggesting a promising area for future work. }}} ---- CategoryDns CategoryWatch CategoryTemplate
