This detection rule identifies potential brand impersonation of Hulu through various indicators. It checks if the sender's display name contains 'Hulu' or closely resembles it via a Levenshtein distance (allowing for minor typographical errors). The rule also considers the sender's email domain for any similarity to Hulu or explicitly known similar domains such as 'lulu.com' or 'hudu.com', ensuring that these domains don't pass through without additional scrutiny. Furthermore, it evaluates the recipient email addresses to see if they are valid, and employs machine learning techniques to analyze logos in message screenshots, checking for the presence of Hulu's branding with a specified confidence level. Essential to this rule is the filtering on sender domains, where any domain that matches Hulu's root domains but fails DMARC checks will trigger the rule, while unsolicited messages by the sender are also factored in to rule out legitimate communications. This detection helps in identifying credential phishing attempts or spam that attempt to exploit the Hulu brand.
