A Microsoft investigation linked AI-assisted messages to attempted business payment fraud. The campaign reportedly used executive impersonation to convince employees to authorize transfers approaching $50,000.

A Microsoft Security report detailed how attackers are combining executive impersonation with artificial-intelligence tools to target corporate payment processes. The campaign reportedly generated more than one million financial-fraud emails and attempted to persuade accounts-payable staff that payment instructions came from company leaders. The requested transactions included ACH payments of nearly $50,000, creating a direct risk of substantial losses for businesses that rely on email approvals. The fraud pattern is consistent with business email compromise, but AI can make messages more polished, personalized, and easier to produce in bulk. Businesses should require independent confirmation for unusual payment requests, especially those involving secrecy, urgency, new beneficiaries, or changed bank details. Finance teams should also use dual approval, transaction limits, phishing-resistant authentication, and continuous monitoring for suspicious mailbox activity.
