What is Vishing? - Protecting Against Voice Phishing
Understand what vishing is, how it differs from phishing, and effective strategies to protect yourself from this type of social engineering attack.
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.

About Corbado
Corbado is the Passkey Intelligence Platform for CIAM teams running consumer authentication at scale. We help you see what IDP logs and generic analytics tools can't: which devices, OS versions, browsers and credential managers support passkeys, why enrollments don't turn into logins, where the WebAuthn flow fails and when an OS / browser update silently breaks login, all without replacing Okta, Auth0, Ping, Cognito or your in-house IDP. Two products: Corbado Observe layers observability for passkeys and any other login method. Corbado Connect adds managed passkeys with analytics built in (alongside your IDP). VicRoads runs passkeys for 5M+ users with Corbado (+80% passkey activation). Talk to a Passkey Expert →
