Service Abuse: SurveyMonkey Survey From Newly Registered Domain

Sublime Rules

View Source
Summary
This ASR rule targets potential misuse of SurveyMonkey surveys originating from newly registered domains. It specifically looks for replies to SurveyMonkey surveys where the reply-to email address comes from a domain that has been registered in the last 30 days. The rule includes several checks to validate the legitimacy of the sender by ensuring that emails are sent from recognized infrastructure and that the SPF and DMARC authentications pass. It also checks against historical data to rule out legitimate prior communication with the reply-to email and blocks those that haven't been solicited or have been previously marked benign. This rule helps mitigate the risk of credential phishing attacks, particularly those leveraging social engineering tactics through email surveys.
