HCRG Care Group Listed by medusa Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target healthcare providers across the UK and beyond, often combining encryption with data theft to increase pressure on organisations that hold sensitive operational and personal records. In this landscape, listings on criminal leak sites have become a common way for attackers to claim success and threaten further publication of stolen material.

On 18 February 2025, the healthcare organisation HCRG Care Group was listed by the ransomware group known as medusa. Public reporting states that internal files were exfiltrated and that the total volume of data involved is 2.275 terabytes. The number of people affected remains unknown, and independent confirmation of the full scope is limited. The listing itself is a claim by the group; it has not been independently verified in the available record.

Breaking down the breach

According to the reported details, HCRG Care Group was named on medusa’s leak site in connection with a ransomware attack that included the exfiltration of internal files. The total amount of data leakage is given as 2.275 terabytes. A direct download link for a large file tree was referenced in the reporting, reflecting the volume involved. No further technical details about the initial intrusion method, the precise date of compromise, or whether systems were also encrypted have been disclosed in the available facts. The number of individuals whose information may have been involved is listed as unknown.

Because the primary source of the claim is the threat actor’s own listing, the incident should be treated as an unverified assertion until the organisation or independent investigators provide additional confirmation. Public detail on containment, notification of regulators, or any ransom demand remains limited.

The group behind it: medusa

Medusa is a well-documented ransomware operation that has been active for several years. Like many modern groups, it typically employs a double-extortion model: encrypting systems while also stealing data and threatening to publish it if a ransom is not paid. The group maintains a leak site where it posts victim names, sample files, and sometimes large archives of stolen material. Medusa has previously claimed attacks against organisations in multiple sectors, including healthcare, manufacturing and professional services, often advertising multi-terabyte data sets.

In this case the group claims to have listed HCRG Care Group and to have obtained 2.275 terabytes of internal files. No additional statements attributed specifically to medusa about this victim—beyond the listing and the stated data volume—appear in the provided facts. Readers should therefore regard the claims as assertions by the attackers rather than established findings.

HCRG Care Group and its sector

HCRG Care Group is a UK healthcare company founded in 2006. It provides services that include physician clinics and specialty clinics. Its corporate office is located at The Heath Business and Technical Park, Runcorn, Cheshire, WA7 4QX, and it employs approximately 5,000 people. Organisations of this type sit at the intersection of clinical care delivery and the administrative systems that support appointments, records, staffing and finance.

Healthcare providers routinely process large volumes of personal and operational data. A ransomware incident affecting such an organisation raises concerns not only about continuity of care but also about the potential exposure of information that could be used for identity fraud, targeted scams or further intrusion into related systems. The scale of the claimed data volume—over two terabytes—underscores why listings of this kind attract attention from patients, staff and regulators.

The information in question

The available facts state that internal files were exfiltrated in the ransomware attack and that the total data leakage amounts to 2.275 terabytes. No more granular inventory of data types—such as patient records, employee details, financial documents or clinical notes—has been publicly named. Exact contents therefore remain unconfirmed.

Healthcare organisations of this size and type typically hold a mix of administrative files, staff records, contractual material and, in many cases, information linked to patient services. Until a fuller disclosure is made by the organisation or by independent analysis of any published material, it is not possible to state with certainty which categories of data were included in the claimed 2.275-terabyte set.

The real-world impact

For individuals, the principal risks associated with any large-scale exfiltration of internal healthcare files include the possibility of identity theft, phishing or social-engineering attempts that reference genuine organisational details, and longer-term concerns about the confidentiality of personal or medical information. Because the number of people affected is unknown and the precise data types are undisclosed, the concrete exposure for any given person cannot yet be quantified.

For the organisation, a ransomware incident of this claimed scale can disrupt operations, generate regulatory scrutiny under UK data-protection rules, and require significant resources for investigation, notification and recovery. Even when systems are restored, the publication or sale of stolen files can create ongoing reputational and legal consequences. These outcomes depend on whether the group’s claims prove accurate and on how any released material is used.

If your data was in this claimed breach

If you have a connection to HCRG Care Group—as a patient, employee or contractor—consider practical steps while official details remain limited. Monitor financial and medical accounts for unusual activity, be cautious of unsolicited emails or calls that reference the organisation, and enable multi-factor authentication on important online services. If you receive formal notification from the company, follow the guidance it provides. You can also run a free exposure scan of your email address to check whether your information has already appeared in known breach data sets. Keep records of any suspicious contact and report confirmed fraud to the relevant authorities.
