at this point, the criminal uses otp agency to trigger a robo—call to you, posing as your bank. i've obtained a demonstration of one of these calls from inside otp agency. it shows just how convincing they can be. john seymore, this is an automated call from halifax bank. they pretend to be calling to prevent fraud. they say if you want to stop the transaction, you need to give them your one time passcode. an authorised payment of £85.23 was made using your debit card ending in 1312. in order to cancel this transaction, please enter the code that you received by text message followed by the hash key after the beep. if you follow these instructions, the criminals will have everything they need to take your money. i was not the only one investigating them.
