Messaging, Malware and Mobile Anti-Abuse Working Group (M3AAWG) supports the U.S. Federal Trade Commission’s (FTC) proposed rulemaking as part of its current mission in protecting the public from deceptive or unfair business practices to include a critical role in protecting consumers from ongoing and increasing impersonation schemes targeting businesses and governments alike. M3AAWG suggests additional regulatory solutions and best practices to complement the goals of this rule, such as clarifying the scope of the rule to include the use of domain names in impersonation schemes and the use of technologies that enable impersonation. M3AAWG notes that the investigation of impersonation schemes requires cooperation and information from many entities. Specifically, WHOIS information is vital to the investigation of impersonation scams. The Comment identifies best practices to tackle impersonation scams, including the validation of commercial senders, DNS mitigation steps, and adoption of trusted notifier relationships to facilitate abuse reporting.
