Vishing as the Front Door to MFA Bypass

Threat reporting tied to ShinyHunters and Scattered Spider-linked activity shows voice phishing (vishing) being operationalized as a coordinated access vector against enterprise identity systems.

Rather than relying solely on email-based phishing, attackers now call employees directly, impersonating IT support, security teams, or identity administrators. These calls are not random — they are tightly coupled with live phishing infrastructure and identity workflows.

The goal is not to “steal a password”; it is to walk the victim through a legitimate authentication event while the attacker intercepts the outcome.

This is why legacy MFA continues to “work,” yet organizations are still getting breached.
