6. Grandparent scam
Imagine a granny who gets the call or email, telling her that her favorite grandson is arrested abroad and urgently needs money for bail. He also begs her not to tell the parents, because he will be in even more trouble. Oh, and there’s no point in calling him because his phone is taken away from him, so granny should just send the money via the Western Union. Except there’s no arrest and grandson has no idea what’s going on. The scammer just did their homework and gathered the details of granny’s family.
