Key terms

  • Business email compromise

    Business email compromise is a fraud in which an attacker uses a real or spoofed business email account to convince someone with payment authority to send funds or change bank details for a legitimate obligation.

  • Wire transfer

    A wire transfer is a real time, credit push transfer of funds between banks that settles with finality, meaning it cannot be unilaterally reversed once the receiving bank accepts it.

  • Callback verification

    Callback verification is the control of confirming a payment instruction or a bank detail change by telephoning the counterparty on a number already held on file, never a number supplied in the request itself.

  • Out of band verification

    Out of band verification confirms a request over a channel entirely separate from the one that carried it, so that compromise of a single channel cannot both make and confirm the request.

  • Account takeover

    Account takeover is unauthorized control of a legitimate account, such as an online banking profile or a business mailbox, which the attacker then uses to move money or manipulate payment instructions from inside a trusted identity.

Questions

Why is wire fraud so hard to recover from?

Wires settle quickly and are generally final once the receiving bank releases funds, so prevention before sending matters far more than recovery afterward.

What is the most common way businesses are tricked into a fraudulent wire?

A changed payment instruction, usually delivered by a compromised or spoofed email that appears to come from a known vendor or executive.
