This detection rule targets potential service abuse by monitoring inbound email messages from Adobe's legitimate email domain. It specifically looks for messages that suggest actions related to document or payment approvals, which may be indicative of business email compromise (BEC) or credential phishing attempts. The rule utilizes a combination of content analysis, header analysis, and sender analysis methods to assess the legitimacy of the messages. By employing regex pattern matching, the rule checks for phrases such as 'approved', 'view document', or 'payment approval' within the body of the email. An alert is triggered when these terms are present in emails that are sent from the domain email.adobe.com, which can help organizations mitigate risks associated with targeted phishing campaigns that aim to exploit social engineering tactics. The severity of this rule is classified as medium, emphasizing the importance of vigilance in email communications regarding sensitive approvals.
