Protecting organizations from AI-assisted executive impersonation and invoice fraud
Microsoft tracked a campaign of over one million AI-crafted CEO-impersonation emails seeking ~$50,000 ACH payments with fabricated ServiceNow invoices.
Between August 3 and 5, Microsoft detected a campaign of more than one million fraud emails, 87.7% of them targeting US enterprise users, sent through multiple third-party email delivery service accounts. The actor impersonated CEOs, CFOs, and presidents of targeted companies, urging accounts payable staff to process an ACH payment of nearly $50,000. Lures layered executive impersonation, lookalike domains, a fabricated ServiceNow 'Annual Subscription' invoice personalized to the recipient, and forged forwarded email threads; Microsoft found no evidence ServiceNow or the referenced executives were compromised. Microsoft observed indicators consistent with generative AI-assisted template creation, while leftover inconsistencies such as missing forwarding headers and mismatched display names gave defenders detection cues.
Hackers Impersonate CEOs in 1 Million Emails to Trick Employees Into $50,000 Payments
A BEC campaign sent over one million fake CEO invoice emails, mostly to US firms, urging ~$50,000 ACH transfers to attacker accounts.
Microsoft analysts tracked a business email compromise campaign that sent more than one million messages between August 3 and 5, with 87.7% targeting US recipients. Emails impersonated CEOs, CFOs, and presidents and carried fake ServiceNow-branded subscription invoices directing accounts-payable staff to make ACH transfers of nearly $50,000 to attacker-controlled accounts. No malicious attachments or malware were used, and researchers observed signs consistent with AI-assisted template development. Lookalike domains such as service-nowinc[.]com and third-party delivery accounts were used, while named firms like ServiceNow showed no evidence of compromise.
