Your bank is on the phone. The man knows all your details. He says there's a problem on your account. Would you know what to do?
Scam Secrets is the new series lifting the lid on the techniques criminals use to steal your money.
BBC reporter Shari Vahl is joined by criminologist and forensic linguist Dr Elisabeth Carter and former scammer Alex Wood to get inside the mind of the criminals and highlight the red flags that should set alarm bells ringing.
In this first episode, they hear how a seemingly innocuous TV licensing email paved the way for a scarily sophisticated scam that drained a businesswoman's bank account.
