This rule detects email-based business fraud (BEC) targeting the organization, specifically looking for executive impersonation paired with financial lure terminology and sender domain mismatches. It utilizes both a blocklist of known fraudulent sender indicators (domains and addresses) and a heuristic approach analyzing discrepancies between the envelope sender domain and the header sender domain combined with executive titles in display names and invoice-related keywords.
Detects high-value wire transfers (>= €600,000) directed to beneficiaries in Hong Kong that contain suspicious memo or description fields related to confidential acquisitions or professional service retainers, potentially indicating business email compromise (BEC) or fraudulent financial activity.

Detects forged Citibank payment confirmation/account statement PDFs used in Phantom Deal BPC fraud to falsely demonstrate wire transfer progress; requires combination of bank branding with fraud-specific SWIFT/routing/CTA artifacts
Detects anomalous, high-value wire transfers involving keywords related to advance-payment or M&A-related fraud (e.g., 'advance retainer'), directed towards beneficiaries in Hong Kong using previously unseen bank accounts. The rule effectively filters out known, approved beneficiary accounts to focus on potentially malicious transactions.
This rule monitors for inbound external emails where the sender requests private communication (e.g., 'private email' or 'personal address') in combination with keywords related to sensitive business topics like M&A, legal, or urgent financial transactions. This pattern is characteristic of Business Email Compromise (BEC) or social engineering attempts designed to move sensitive conversations outside of monitored corporate channels.
Detects incoming emails to finance or accounts payable aliases that contain urgent payment-related keywords and suspicious patterns, such as subject lines including dollar amounts or emails where the Reply-To address domain differs from the Sender domain. This activity is highly indicative of BEC fraud attempts targeting payment redirection.

Detects inbound emails containing keywords associated with known ransomware extortion tactics (e.g., mention of specific ransomware names, data leaks, and payment demands). The rule filters for inbound traffic to identify external threats while excluding potential internal-generated traffic.
