“We are doing a security check for your account.”

Sample conversation:

• Hi, this is Mika from xxx bank.
• We are doing a security check for your account to make sure that you can receive the OTP, or one-time passwords.
• In a short while po, we will be doing a test transaction and you will receive the OTP as a text message.
• Please stay on the line until it arrives, then share it with me para we can verify that you can receive the correct passwords.
• If your passwords are wrong, you won’t be able to authorize your future transactions so very important ito.

Things to note:

• Call from unregistered number
• Caller introduces herself as a bank employee.
• Mention of security checking to seem legitimate
• Mention of difficulty in account closure to scare the recipient
• Attempt to rationalize sharing the OTP

Sample conversation was created to reflect a similar case.
