What is vishing and how does it differ from smishing?

Vishing, or voice phishing, uses phone calls to trick victims into revealing sensitive information. Attackers often spoof caller ID to appear as a bank, government agency, or tech support and create urgency to pressure immediate action. Smishing, or SMS phishing, uses text messages containing malicious links or requests for sensitive information, often claiming to be delivery notifications, account alerts, or prize winnings. Both exploit the trust people place in phone communications and the tendency to act quickly on mobile devices.
