Common Business Email Compromise Scenarios

BEC incidents do not always look the same. They can range from a single fraudulent payment request to a wider compromise of cloud email, identity systems, and internal processes.

monitoring
Executive Impersonation

Attackers impersonate a CEO, CFO, or other senior leader to pressure staff into making urgent payments or disclosing sensitive information.

Supplier or Invoice Fraud

Email communications are manipulated to change bank account details, redirect invoices, or interfere with legitimate payment workflows.

Payroll Diversion

Threat actors pose as employees or compromise accounts to request payroll changes or redirect salary payments.

FAQ

Frequently Asked Questions

What Is Business Email Compromise?

Business Email Compromise is a form of cyber-enabled fraud where attackers use email to impersonate trusted people or exploit legitimate accounts to manipulate payments, data sharing, or business processes.

Does BEC Always Involve a Hacked Mailbox?

No. Some incidents involve direct compromise of a mailbox or cloud identity account, while others rely on spoofed domains, lookalike addresses, or impersonation without full account compromise.

Can You Help if Funds Have Already Been Transferred?

Yes. Even where financial loss has already occurred, rapid investigation is important to support containment, evidence preservation, internal response, and next-step decision-making.

Can You Investigate Microsoft 365 Email Compromise?

Yes. Microsoft 365 environments are commonly involved in BEC matters, and investigation may include mailbox access, authentication activity, forwarding rules, and related identity indicators.
