CEO Fraud
A scam where an attacker impersonates the CEO to trick an employee into wiring funds or sending sensitive data.
Detailed Definition
CEO fraud is a subset of Business Email Compromise (BEC). The attacker typically spoofs or compromises the email account of a high-ranking executive and sends an urgent request to a subordinate—often someone in finance or HR. The urgency and authority of the request are designed to override the employee's usual skepticism.
Why It Matters
This highlights the danger of implicit trust in organizational hierarchy. Robust out-of-band verification procedures (like verbal confirmation) are essential defenses against CEO fraud.
Real-World Examples of CEO Fraud
An accounting employee receives an email late on a Friday from the 'CEO' saying they are in a secret negotiation to acquire a competitor and need an immediate wire transfer to a foreign consultant's account to secure the deal.
1. Case Study: CEO Fraud Initial Access
In an observed attack pattern, an adversary utilizes CEO Fraud to compromise an organization's initial perimeter. The threat actors are then able to maneuver laterally and escalate their privileges across the victim's infrastructure.
2. The Role of CEO Fraud in Zero-Trust Defense
Organizations actively defend against this by integrating their CEO Fraud policy with continuous monitoring and strict identity verification processes, removing default-allow actions entirely.
CEO Fraud Execution
Impersonation
Attacker mimics the CEO using spoofing, a lookalike domain, or a compromised account.
Urgency

Targeting
The request is sent to an employee with the authority to initiate wire transfers.
Compliance
Fearing reprimand or wanting to impress, the employee processes the request without secondary checks.
Theft
The company funds are transferred directly into the attacker's offshore bank account.
