Vishing Attack Provides Threat Act with Access to Quantum Health Network
Quantum Health, a healthcare navigation and care coordination company, disclosed a data breach after a vishing attack — a voice-based social engineering scheme — gave threat actors unauthorized access to its network. Heart of America Medical Center was also named in connection with recent breach announcements.
Why this matters: Vishing is just a phone call. Someone convinces an employee to hand over credentials or access, and suddenly an outsider is inside a healthcare network. Healthcare data is the most sensitive kind — diagnoses, treatments, insurance details, personal history. People did not choose to share that with attackers. They shared it because a company they trusted got manipulated over the phone. The real accountability question is what training and verification controls Quantum Health had in place before someone picked up.
