UK-based healthcare giant HCRG Care Group has confirmed it is investigating a cybersecurity incident after a ransomware gang claimed to have breached the company's systems, stealing troves of sensitive data. The organization, which provides community health and care services to over half a million patients across the UK, has been listed on the dark web leak site of the prolific Medusa ransomware group.

HCRG Care Group, previously known as Virgin Care and now owned by Twenty20 Capita, partners with National Health Service (NHS) trusts and local authorities around the UK to deliver healthcare services, including urgent care, sexual health, and adult and child social care services. The company has over 5,000 employees, making it one of the largest independent providers of community health and care services in the UK.

According to Medusa, the ransomware group claims to have compromised HCRG's systems, stealing more than two terabytes of data. Samples of the allegedly stolen data shared by Medusa and seen by TechCrunch appear to include employees' personal information, sensitive medical records, financial records, and government identification documents, such as passports and birth certificates. The stolen data could potentially put thousands of patients and employees at risk of identity theft and other malicious activities.

HCRG spokesperson Alison Klabacher told TechCrunch in an emailed statement that the company is "currently investigating an IT security incident" and has "recently identified a post on the dark web by a group claiming responsibility." Although the company declined to say what types of data were accessed, it did not dispute Medusa's claims. The company also refused to disclose how many individuals are affected by the breach.

HCRG has informed the UK's Information Commissioner's Office and other regulators about the breach. The company's services are continuing to operate, and patients are advised to continue with their appointments and access healthcare services as usual. "Our team has not observed any suspicious activity since the implementation of immediate containment measures, and we are working with external forensic specialists to investigate the incident," the spokesperson said.

The Medusa ransomware group is threatening to publish the allegedly stolen data unless HCRG pays the gang a ransom demand of $2 million. HCRG wouldn't confirm how it was compromised, but Medusa is known to exploit unpatched vulnerabilities in remote desktop software. This raises concerns about the company's cybersecurity practices and its ability to protect sensitive patient data.

The incident highlights the growing threat of ransomware attacks on healthcare organizations, which can have devastating consequences for patients and employees. It also underscores the need for healthcare providers to prioritize cybersecurity and invest in robust defenses to protect sensitive data. As the investigation continues, HCRG Care Group must take swift action to contain the breach, notify affected individuals, and implement measures to prevent similar incidents in the future.

In the broader context, this incident serves as a stark reminder of the importance of cybersecurity in the healthcare sector. With the increasing reliance on digital systems and the growing threat of cyberattacks, healthcare providers must remain vigilant and proactive in protecting sensitive patient data. The UK's National Health Service (NHS) has already faced several high-profile cyberattacks in recent years, and this incident serves as a wake-up call for the entire healthcare industry to prioritize cybersecurity and protect patient data.
