What is Vishing? - Protecting Against Voice Phishing

What is Vishing?#

Vishing (voice-based phishing) is a social engineering attack conducted via telephone, where attackers impersonate other persons or institutions to extract personal information. These attackers often pose as government officials, bank representatives, or tax agents to exploit the trust and authority perceived in these roles.

Using psychological manipulation, they may threaten or deceive victims into disclosing sensitive information, crucial for committing fraud or accessing financial accounts. This form of attack leverages voice communication to increase the urgency and authenticity of the threat, making it a potent variant of phishing.

Vishing vs. Phishing and Smishing#

• Phishing: Primarily email-based, uses deceptive emails to steal data.

• Vishing: Involves direct voice calls, creating a more immediate and personal sense of urgency.

Prevalence and Sophistication#
