Fraud Types
Using phone calls, usually with a spoofed or impersonated caller ID, to trick victims into revealing credentials, codes, or payments.
Vishing campaigns impersonate banks, tax authorities, delivery companies, and increasingly internal IT help desks. Attackers now combine spoofed caller ID with AI-generated voices and data harvested from breaches.
One-time-passcode interception is a particularly damaging variant, where the caller keeps the victim on the line while draining an account.
Vishing traffic that originates on your network attracts regulatory attention faster than almost any other fraud type, because the consumer harm is direct and well documented.
Presenting a calling number the caller is not authorized to use, in order to disguise the call's true origin or impersonate a trusted party.
An automatically dialed call that delivers a pre-recorded or artificial voice message, legal only with the right consent or exemption.
A list of telephone numbers that should never appear as the calling number, such as inbound-only government and bank lines, which carriers may block outright.
