This detection rule is designed to identify suspicious QuickBooks notifications that potentially indicate phishing attempts. The rule specifically checks for messages coming from the legitimate sender, Intuit, ensuring that email authentication standards such as SPF and DMARC are passed. It filters out payment confirmation messages to focus on emails that contain specific keywords associated with malicious activities. The logic employs regular expressions to match against various templates of the email content that may contain alarming phrases, such as indications of payment issues or verification requests. By analyzing the HTML body of the email against these patterns, it helps to detect potential callback phishing, credential phishing, or business email compromise (BEC) fraud scenarios.
