CEO Fraud

Reviewed byCybersecurity entrepreneur & security researcher

What is CEO Fraud?

CEO FraudA subtype of business email compromise in which an attacker impersonates a senior executive to pressure an employee into performing an unauthorised wire transfer or sensitive action.


CEO fraud — sometimes called "whaling-driven BEC" — relies on a believable executive persona (spoofed domain, look-alike address, or hijacked mailbox) combined with authority and urgency. The attacker typically targets finance, accounting, HR, or executive assistants, requesting confidential wire transfers, gift-card purchases, payroll changes, or release of tax/PII data. Effective controls include callback verification using a known phone number, dual-approval workflows for payments, DMARC reject with alignment, external banners on inbound mail, and recurring scenario-based training so staff feel safe to challenge unusual executive requests.

Examples

  1. 01

    A spoofed CEO email instructs the controller to wire funds for a "confidential acquisition".

  2. 02

    An attacker poses as the CFO and asks HR to share all employee W-2 forms.
