How they work
You get an unknown text, email, or call that appears to be from a reputable financial institution, such as SECU, claiming there is a problem with your account. You are encouraged to provide your card number, personal information, online credentials, or a One-Time Passcode / Two-factor Authentication. This scam is known as phishing and is used to get personal information and con people out of money.
The scammer may claim to be from the fraud department and convince you that your accounts are at risk for identity theft. They may even tell you there is an employee of the financial institution involved in defrauding your account and encourage you not to say anything to any employees in the branch. They encourage you to withdraw large amounts of cash to be sent through a Cryptocurrency ATM to an account that will keep your funds safe while the investigation is ongoing. You are told that if anyone asks, you should fabricate a reason for the cash withdrawals.
