A

Advance fee
A payment demanded before a promised benefit is released — a prize, an inheritance, a loan, a job, or your own money.
Authorised push payment fraud
Fraud in which the victim makes the payment themselves, having been deceived — as opposed to unauthorised fraud, where the criminal takes the money directly.

B

Business email compromise
Fraud that redirects a legitimate business payment by impersonating an executive, a supplier or a lawyer, usually from inside a compromised mailbox.

C

Chargeback
A card payment reversed by the issuer at the cardholder's request. It is the strongest consumer protection in retail payments, and it is exactly what fraud schemes are designed to avoid.

D

Deepfake

M

Money mule
A person whose bank account is used to receive and move criminal proceeds, whether knowingly, unwittingly, or under coercion.

SIM swap
Taking over a victim's phone number by persuading or bribing a mobile carrier to move it to a SIM the attacker controls.
Smishing
Phishing delivered by text message — a delivery notice, a toll charge, a bank alert — designed to get you onto a fake login page.

T

Task scam
