Fake banking advisor – How to recognize it and protect yourself from it in 2026

The fake bank advisor scam is a telephone fraud in which a scammer poses as an employee of your bank's fraud department. By claiming suspicious transactions on your account, he pushes you to validate transfers yourself or provide authentication codes — which allows him to empty your account. It particularly targets older people, but affects all profiles.

How the scam works, step by step

1. 1
   The incoming call — a familiar number

   Your phone rings. The screen displays your bank number — or a number very close to it. The fraudster uses a technique called spoofing (number spoofing) which allows it to show any caller ID. This is enough to create a first feeling of legitimacy.

2. 2
   The credible alert — he knows things about you

   The scammer presents himself as an advisor to the “fraud department”. He often knows your first name, your bank, sometimes the amount of your last transactions. This information is purchased on compromised databases. It tells you that one or more suspicious transactions have been detected on your account.

3. 3
   Emergency set in — no time to think

   The scammer emphasizes the urgency: “If you don’t validate now, the funds will leave.” It creates pressure that prevents you from checking, calling your own bank back, or consulting a loved one. Precipitation is at the heart of the system.

4. 4
   The authentication request — the centerpiece

   He asks you to validate a transaction in your banking application – “to block suspicious funds” – or to communicate the code received by SMS. In reality, this validation authorizes a transfer to his account. You are the author of the operation in the eyes of the system.

5. 5
   The disappearance — and the consequences

   The scammer hangs up. Funds are transferred to intermediary accounts, often abroad. According to the OSMP (Banque de France, 1st half of 2023), the average loss per victim of a fraudulent transfer amounted to €3,497. In the most serious cases, several tens of thousands of euros can disappear in a few minutes.

The 5 warning signs to know

These signals alone do not prove that it is a scam. But their presence — and especially their combination — should alert you immediately.

• You are asked to validate a transaction or give an SMS code. No real banking advisor ever asks this. Authentication codes are strictly personal and must not be communicated to anyone.

• The urgency is absolute and the deadline very short. “We must act now”, “in the next 10 minutes”, “don’t hang up”. Rushing is a deliberate technique to prevent thinking.

• We ask you not to contact your bank or not to tell your loved ones. A legitimate advisor has no reason to isolate you.

• You are asked to transfer funds to a “secure” account. Banks never do this. Buffer accounts do not exist in official procedures.

• The number displayed matches that of your bank, but the call seems unusual to you. Trust your instincts. The number displayed may be spoofed — this is not proof of legitimacy.

What to do if you are a victim?

If you have validated a transaction or transmitted a code, act within the following hours. Every minute counts.

1. File an objection immediately. Call the number indicated on the back of your bank card or on your contract. Report the fraudulent transaction and request that your account be blocked if necessary.
2. Don't hang up on the scammer — hang up and call back yourself. If you have any doubts during the call, hang up. Wait a few minutes, then call your bank again by dialing their number yourself.
3. File a complaint. Go to the nearest police or gendarmerie. Keep all elements: statements, calling numbers, timestamps.
4. Report the scam. On cybermalveillance.gouv.fr to obtain assistance and contribute to detection. On 33700.fr to report fraudulent numbers.
5. Contact the banking mediator if your bank refuses reimbursement. In 2023, the OSMP issued recommendations to improve the care of victims of manipulation fraud. Remedies exist.
