You receive a call from someone who sounds exactly like your adult son. He says he has been in an accident, is being held at a police station, and needs you to transfer bail money immediately. He tells you not to call anyone else because it could complicate the legal situation. What is the right response?

Hanging up and calling back on a number you already have is the single most effective defense against AI voice clone scams. It costs nothing and breaks every version of this scam. Asking personal questions does not help, because scammers research their targets using social media and can often answer questions about family details convincingly. Staying on the line keeps you in the scammer's control and under their time pressure. The instruction not to call anyone else is itself a major warning sign: that is the isolation tactic covered in Module 3. The P and U in PAUSE apply directly here: pause when something triggers panic, and use a channel you already control to verify.
