Social engineering
Manipulating people, not machines — the common engine beneath almost every scam.
Social engineering is the manipulation of people, rather than the hacking of machines, to get money, access or information. It is the common engine beneath nearly every scam: instead of breaking a system, the fraudster persuades a human to open the door. The levers are predictable — urgency, fear, authority, curiosity, sympathy and the wish to be helpful — deployed to hurry you past the moment of doubt where you would normally pause.
A caller impersonating your bank, an email that borrows a boss's authority, a 'you must act now' deadline, a stranger offering easy money: all are social engineering wearing different costumes. Recognising the technique is the best general defence, because it stays constant even as the specific stories change every season. Slow down whenever a message makes you feel rushed or afraid; verify any request through a channel you chose yourself rather than the one that contacted you; and be most careful precisely when you are told to hurry or to keep something secret. Our field guide to common types of scam shows how this one principle underlies phishing, romance fraud, investment cons and more.
