Maria gets a call from someone claiming to be from her bank's fraud department. The caller says her account has been compromised and she must transfer her funds to a safe account immediately. He also tells her not to mention the call to anyone, including family. What should Maria do first?

Two things in this call are instant red flags: urgency and secrecy. No legitimate bank will tell you to act immediately and keep it from people you trust. Those two tactics together are how scammers push people into decisions they would never normally make. The right move is to end the call and reach the bank independently using a number you already know is real. Using a number the caller provides defeats the whole point.
