Executive Targeting via Purchase Order and Financial Phishing Lures
This rule detects potential spearphishing attempts targeting high-value individuals (CEO, CFO, IT Admin) within an organization. It looks for emails sent to these individuals with subjects commonly associated with financial phishing or social engineering lures, such as "Invoice," "Wire Transfer," "Payment," "Urgent," or "Purchase Order." The rule also checks if these emails contain attachments, which is a common vector for delivering malware or credential harvesting documents in phishing campaigns. It summarizes the attempts by sender, recipient, and day, counting the number of attempts and listing the attachments.
