Voice phishing, or "vishing," is a phishing technique where attackers use telephone calls to deceive victims into sharing sensitive information, often by impersonating trusted entities. Vishing attacks exploit the human trust in voice communication and the immediacy of phone interactions to bypass typical security measures.

Vishing is effective because it leverages the human voice to build trust and create urgency. Attackers often impersonate trusted organizations or government bodies, pressuring victims into providing sensitive information or making financial transfers. As phone-based scams increase, it is critical to be cautious about sharing personal or financial details over the phone and to always verify the legitimacy of the caller.
