Rhysida Ransomware Demands $3.6 Million for Children’s Stolen Data

The Rhysida ransomware group has struck again, this time targeting Lurie Children’s Hospital in Chicago and demanding a staggering $3.6 million ransom for the return of stolen data. This attack underscores the growing threat ransomware poses to healthcare institutions and the urgent need for stronger cybersecurity measures. This incident follows a disturbing trend of Rhysida targeting the healthcare sector, exploiting vulnerabilities and putting patients’ well-being at risk.

Lurie Children’s Hospital Under Siege

In early February 2024, Lurie Children’s Hospital, a leading pediatric care facility serving over 200,000 children annually, experienced a significant cyberattack. The Rhysida ransomware group quickly claimed responsibility, listing the hospital on their dark web extortion portal and showcasing 600 GB of allegedly stolen data. This data reportedly includes sensitive patient information, medical records, and other confidential documents. The attack severely disrupted the hospital’s operations, forcing staff to revert to manual processes for prescriptions, impacting scheduling, and limiting access to medical records. Email, phone systems, and the MyChart patient portal also suffered disruptions.

Rhysida’s Escalating Tactics

Rhysida initially offered the stolen data to a single buyer for 60 bitcoins (equivalent to $3.6 million at the time) with a seven-day deadline. If no buyer emerged, they threatened to sell the data to multiple actors, further escalating the risk of widespread exposure and misuse of sensitive patient information. This tactic of double extortion, where data is stolen before encryption, has become increasingly common among ransomware groups, putting immense pressure on victims to pay the ransom. Rhysida has exhibited a concerning pattern of targeting healthcare organizations. Previous victims include Prospect Medical Holdings, a network of 17 hospitals and 166 outpatient clinics, and numerous other medical facilities across the United States.

The Growing Threat to Healthcare

The healthcare sector has become a prime target for ransomware attacks due to several factors. The sensitive nature of patient data, the often outdated IT infrastructure in hospitals, and the critical role healthcare plays in society make it a lucrative target for cybercriminals. The consequences of these attacks can be devastating, ranging from financial losses and reputational damage to disruptions in patient care and even fatalities.

Protecting Healthcare from Ransomware

Combating the ransomware threat requires a multi-pronged approach. Hospitals must invest in robust cybersecurity measures, including:

• Strengthening network security: Implementing strong firewalls, intrusion detection systems, and other security measures to prevent unauthorized access.
• Regular data backups: Ensuring regular and secure backups of critical data to enable quick recovery in case of an attack.
• Employee training: Educating staff about phishing scams and other social engineering tactics used by ransomware groups.
• Incident response planning: Developing and regularly testing incident response plans to minimize the impact of an attack.
• Collaboration and information sharing: Sharing information about ransomware attacks and best practices within the healthcare community.

The attack on Lurie Children’s Hospital serves as a stark reminder of the increasing cybersecurity threats facing the healthcare sector. By taking proactive steps and implementing stronger defenses, healthcare organizations can better protect themselves, their patients, and the critical services they provide. As of today, June 16, 2025, the threat of ransomware continues to evolve, emphasizing the importance of ongoing vigilance and adaptation in the face of this digital pandemic.
