In this Advisory, SSAC describes generic forms of this type of attack. We
consider types and formats of information included in legitimate email messages that various registrars use when corresponding with customers. We discuss how phishers manipulate these information types and formats to create a bogus correspondence that is designed to socially engineer1 the registrar’s customer into visiting an impersonated registrar web site. The attacker designs the impersonated web site to dupe the customer into disclosing domain management account names and credentials. We discuss some of the current recommended practices to minimize or prevent phishing attacks employed by common phishing targets such as financial institutions and large corporations. We recommend measures that registrars can take to make their correspondences with registrants less "phishable” and identify ways for registrants to detect and avoid falling victim to this form of phishing.
