Healthcare Provider Hit by PEAR Ransomware with Potential Data Exfiltration

Colorado Pulmonary Intensivists fell victim to the PEAR ransomware group, which appears to have both encrypted systems and exfiltrated sensitive data before publishing the organization on their leak site. This double-extortion attack is particularly concerning for healthcare organizations as it potentially exposes protected health information (PHI), triggering HIPAA breach notification requirements. The incident demonstrates how ransomware groups increasingly combine data theft with encryption to maximize pressure on victims and highlights the critical need for healthcare organizations to implement comprehensive data protection measures.
