Sanitized example messages
Illustrative, sanitized examples. Personal details are replaced with placeholders such as [phone number] and [fake link].
Hi, this is the fraud team at [Bank Name]. We have detected suspicious activity on your account. For your security, we are sending you a verification code now — please read it back to confirm your identity.
This is [Bank Name] security. A large transaction has just been attempted. We need you to confirm the six-digit code we just sent you to block it.
Your online banking has been locked by our fraud system. I am sending a reset code to [your number ending in XX] — please give me that code so we can restore access.
We are trying to stop an unauthorised payment leaving your account right now. Read me the code on your screen and we can freeze it immediately.
What the scammer wants
To obtain the OTP your real bank has just sent so they can log into your account, approve a transfer, or change your credentials — while keeping you on the phone and distracted.
Red flags in the message
- Caller claims to be your bank but asks you to read back a code they 'sent'
- Urgent language: a fraud or large transaction happening 'right now'
- They already know partial details (last 4 digits, name) — used to seem legitimate
- Pressure to act before the code expires
- They discourage you from hanging up and calling your bank's official number
A safe response
End the call immediately. Your real bank will never ask you to read back a code over the phone. Call your bank on the number on the back of your card to check your account.
What not to send
- One-time passcodes (OTPs)
- Full card or account numbers
- Online banking passwords
What to do if you already replied
- Call your bank's fraud line immediately using the number on your card
- Ask them to freeze your account and reverse any transfers if possible
- Change your online banking password and PIN without delay
Evidence to preserve
- Screenshot the full message or call details
- Note the sender number, email, or profile
- Save any links (without clicking) and payment details
- Record dates and times
