Vishing

Vishing: Fraud by Phone Call

Vishing is voice phishing: a live call or voicemail that impersonates a bank, police force, or technical support to pressure you into moving money or sharing codes.

Overview

What is it

Vishing is deception carried out by voice. A caller claims to be from your bank, the police, a tax office, or a technology company and invents a problem that only they can fix. They may already know some of your details from a data leak, which makes the story convincing. The call is designed to keep you on the line and in a heightened emotional state so that you follow instructions without independent checks.

Entry point

How does it usually begin

Vishing arrives as an unexpected call, often from a number that appears local or matches a real organisation. It can also begin with a voicemail asking you to call back a number. Some campaigns send a text first to warn you that the bank will call, which makes the later call feel expected.

Psychology

The psychological play

A live voice is persuasive. The caller controls the pace, reacts to your hesitation, and uses authority and fear of loss. They may tell you not to hang up and to keep the matter secret, which prevents you from checking with anyone else.

Warning signs

What to watch for

  • The caller says your money is at risk and must be moved to a safe account.
  • You are told to stay on the line and not to tell anyone.
  • The caller asks for a one-time code or your full password.
  • The number is spoofed so it appears to be your bank's real number.
  • You are asked to install remote access software.
  • The caller becomes agitated when you suggest calling back.

Victim perspective

What the victim usually sees

Your phone rings and the display shows your bank's name or a familiar number. The caller knows part of your account history and warns of suspicious transactions. They guide you through what feels like a security procedure.

Anatomy

The anatomy of the deception

  1. 01

    Contact

    You receive an unexpected call from someone claiming to be your bank.

    Defender move

    Hang up and call the number on your card.

  2. 02

    Trust

    The caller quotes real details about you.

    Defender move

    Remember that a data leak can supply those details.

  3. 03

    Pressure

    You are told your money is at immediate risk.

    Defender move

    Treat urgency from an incoming call as a warning sign.

  4. 04

    Request

    The caller asks for a code or for remote access to your device.

    Defender move

    Never share a one-time code or install software on request.

  5. 05

    Payment or Information

    You are guided to move money or read out details.

    Defender move

    End the call and verify with the real organisation.

  6. 06

    Consequence

    Money leaves your account or your device is accessed.

    Defender move

    Call your bank immediately and report the call.

Verification

What to verify

  1. 1End the call and dial the number printed on your card or statement.
  2. 2Ask the organisation to confirm the issue through its app or in writing.
  3. 3Check whether your bank ever asks for codes by phone; most do not.
  4. 4Discuss the call with a trusted person before doing anything.

Protection

How to protect yourself

  • Agree a family rule that no urgent money request is acted on during a call.
  • Never install remote access software at the request of an unexpected caller.
  • Use your bank's app to review transactions rather than trusting the caller.
  • Register with call-blocking or nuisance-call services where available.

If it happened

If you already responded

Act quickly, and don't blame yourself.

  1. 1Hang up and call your bank from a different line or your mobile.
  2. 2If you shared a code, ask the bank to freeze or secure the account.
  3. 3If you installed software, disconnect the device and seek help removing it.
  4. 4Report the call to your national fraud reporting service.

Examples

Real-world examples

Common vishing stories include a fake fraud team warning of a compromised account, a fake police officer asking you to help an investigation, and a fake technical support agent claiming your device is infected.
