PIH Health Under Cyber Siege: A Breakdown of the Ransomware Attack

On December 1, 2024, PIH Health, a Californian healthcare provider serving around 3 million residents, suffered a major ransomware attack. This attack crippled vital systems across three hospitals – Downey, Good Samaritan, and Whittier – along with urgent care centers, doctors’ offices, and home health services. The disruption included the loss of access to patient records, laboratory systems, pharmacies, patient registration, and even internet and phone access. While emergency rooms remained open, staff resorted to manual record-keeping, leading to increased workloads and treatment delays.

The Ransomware Fallout: Data Breach and Legal Action

The attackers claimed to have stolen approximately two terabytes of data, impacting an estimated 17 million patients. The allegedly stolen information includes highly sensitive data such as medical records, home addresses, cancer treatment details, private emails with test results and treatments, employee confidentiality agreements, and around 100 active nondisclosure agreements between PIH Health and other medical organizations. Although PIH Health has not confirmed the full extent of the breach, the incident spurred a lawsuit from a Whittier resident alleging negligence and invasion of privacy.

The Wider Implications: Cybersecurity in Healthcare

This attack on PIH Health exemplifies the escalating cyber threats targeting the healthcare sector. The Sophos report, “The State of Ransomware in Healthcare 2024,” reveals the increasing financial burden of these attacks, with ransom demands frequently exceeding $1 million and average payments reaching $4.4 million. Furthermore, the disruption to operations can result in extended downtime, averaging nearly 14 days for healthcare organizations. The PIH Health incident demonstrates the potential for significant patient harm, financial losses, and reputational damage resulting from these attacks, emphasizing the critical need for improved cybersecurity measures. As healthcare providers increasingly rely on digital systems, protecting patient data and ensuring the continuity of care require a greater focus on cybersecurity infrastructure and preparedness.

The Current Situation and Future Outlook (as of March 17, 2025)

More than three months after the initial attack, PIH Health continues its recovery efforts. While some phone services have been restored, the organization has not yet provided a timeline for full system restoration. The long-term impact of this incident, including the resolution of the lawsuit and the full extent of the data breach, remains to be seen. However, the attack serves as a stark reminder of the persistent threat of ransomware and the need for proactive measures to safeguard patient information and maintain the integrity of healthcare systems.
