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.

Attackers Use Passkey Phishing to Hijack Microsoft Cloud Accounts and Exfiltrate Data

Microsoft details two campaigns: million-email CEO impersonation ACH fraud and passkey-themed vishing that hijacks Microsoft cloud accounts for data theft and extortion.

Microsoft disclosed a campaign that sent over one million CEO-impersonation scam emails between August 3-5, 2026, targeting U.S. accounts payable departments with fake ServiceNow subscription invoices to induce ACH transfers, using generative AI to tailor templates. A second campaign detected since May 2026 uses passkey/MFA-themed voice phishing posing as the IT help desk, redirecting victims via SMS to counterfeit Microsoft sign-in pages and adversary-in-the-middle or device-code flows to hijack accounts. Post-compromise activity includes adding attacker-controlled authentication methods, high-volume Microsoft Graph activity, SharePoint and OneDrive downloads, and mailbox collection via REST APIs. Microsoft attributes initial access to Storm-3121 (linked to ShinyHunters and Falcon extortion) and Storm-3032 (UNC6671, a BlackFile splinter operating the Helix extortion brand).
