Billing software firm hit by ransomware attack
Ransomware group breached Horizon Healthcare RCM, stealing sensitive data and forcing a ransom payment to prevent leak of stolen information.
Healthcare billing platform Horizon Healthcare RCM has confirmed it suffered a ransomware attack, where threat actors stole sensitive data before encrypting its systems. The cybercriminal group, suspected to be affiliated with LockBit, reportedly demanded a ransom, which the company is believed to have paid to prevent public exposure of the stolen data.
The breach occurred in June 2024 and affected Horizon’s cloud-based revenue-cycle management platform. Although the company has not disclosed how many clients were impacted, it has notified healthcare providers using its services and is working with cybersecurity experts to assess the full scope of the incident.
Security analysts believe the attackers exfiltrated significant data, including protected health information, before deploying ransomware. While systems were eventually restored, concerns remain over long-term privacy risks and potential regulatory consequences for affected healthcare organisations.
Ransomware attacks on third-party vendors pose significant risks to the healthcare sector. Experts stress the importance of vendor risk assessments, data encryption, and secure system configurations to limit exposure.
As ransomware actors increasingly target supply-chain providers, proactive monitoring and resilience strategies are becoming essential for safeguarding critical data infrastructure.
