rhodar.co.uk Listed by J Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On 10 June 2025, the UK firm rhodar.co.uk appeared on a ransomware leak site operated by the group known as J. Public reporting states that internal files were exfiltrated during a ransomware attack. The number of people whose data may be involved remains unknown, and the precise contents of the files have not been confirmed beyond the general description of internal material.

For anyone who has worked with, contracted, or been employed by an asbestos-removal and demolition specialist, the practical stakes are straightforward: internal business files can contain names, contact details, project records, health-and-safety documentation, and commercial correspondence. Until more is verified, those individuals have limited public information with which to assess their own exposure.

Breaking down the breach

According to the available record, rhodar.co.uk was listed by the J ransomware group on 10 June 2025. The listing asserts that internal files were taken in a ransomware attack. No further technical detail—such as the initial access method, the duration of the intrusion, the volume of data removed, or any ransom demand—has been disclosed in the public summary. The number of people affected is recorded as unknown. Because the only source for the claim is the group’s own leak-site entry, the incident remains an unverified assertion at this stage rather than a fully confirmed forensic finding.

The group behind it: J

J is a ransomware operation that follows the now-common double-extortion model: encrypting systems while also copying data and threatening to publish it if payment is not made. Like other groups of this type, it maintains a public leak site on which it posts the names of organisations it claims to have compromised, often accompanied by sample files or countdown timers. Public reporting over recent years has shown that such groups typically target mid-sized enterprises across multiple sectors, using phishing, compromised credentials, or unpatched remote-access services as common entry points. They then move laterally, exfiltrate data, and deploy ransomware. No statement from J beyond the listing of rhodar.co.uk itself has been provided in the facts of this case; therefore any specific claims the group may have made about this victim are treated solely as assertions.

About rhodar.co.uk

Rhodar is a United Kingdom company that specialises in asbestos removal, demolition and environmental remediation. It works across education, retail, health and commercial buildings, providing bespoke solutions that rely on specialised equipment and trained personnel. Organisations of this kind routinely hold project files, client contracts, site surveys, employee records, health-surveillance data related to asbestos exposure, and correspondence with regulators and subcontractors. A breach involving internal files therefore carries potential consequences for clients, staff and partner organisations whose information may appear in those records. The company’s focus on safeguarding health and the environment makes the integrity of its operational data especially sensitive.

The information in question

The public record states only that “internal files” were exfiltrated. No inventory of specific data types—such as names, addresses, financial details, medical notes or project plans—has been released. Companies engaged in asbestos remediation and demolition typically maintain records that include employee personal data, client contact information, site-specific risk assessments, waste-transfer documentation and commercial agreements. Because the exact contents remain undisclosed, it is not possible to state with certainty which of these categories, if any, are present in the material claimed by J. Readers should treat any more detailed descriptions circulating online as unconfirmed unless corroborated by the company or independent investigators.

The real-world impact

For individuals, the principal risks are identity misuse, targeted phishing that references genuine project or employment details, and potential embarrassment or regulatory scrutiny if health-related or contractual information surfaces. For the organisation, the consequences can include operational disruption, contractual disputes with clients, regulatory notification obligations under UK data-protection law, and reputational damage within a sector that depends on trust around safety-critical work. Because the scale of the exfiltration and the identities of affected parties are still unknown, the full extent of these impacts cannot yet be quantified. The listing itself, even if later withdrawn or disputed, already places pressure on the company to investigate and communicate.

What to do if you're exposed

If you have a past or present connection with rhodar.co.uk—whether as an employee, contractor, client or site visitor—consider the following practical steps:

• Monitor bank and credit accounts for unusual activity and enable transaction alerts where available.
• Treat unsolicited emails or calls that reference asbestos projects, demolition sites or company personnel with heightened caution; verify any request through a known official channel.
• Change passwords on accounts that may have been used in correspondence with the firm, and enable multi-factor authentication.
• Request a copy of any personal data the company holds about you if you believe it may have been involved, using your rights under UK data-protection law.
• Run a free exposure scan of your email address against known breach datasets to check whether your details have already appeared in public dumps.

Public detail remains limited. Further clarity will depend on official statements from the company or independent verification of the files claimed by J. Until then, measured vigilance is the most useful response.
