Thomaston Mills Listed by royal Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Thomaston Mills, a long-established U.S. textile manufacturer, was listed by the royal ransomware group in a claim reported on March 09, 2023. Public detail indicates that internal files were exfiltrated in a ransomware attack. The number of people affected remains unknown, and broader specifics about timing, method, and full scope have not been disclosed.

For an organisation that supplies bed and bath linens to hospitality, healthcare, and institutional customers, any confirmed exposure of internal material carries practical consequences for the company and for individuals whose information may appear in business records. What is known so far rests on the group’s listing and the limited description of exfiltrated internal files; independent confirmation of the full incident has not been detailed in the available record.

Breaking down the breach

According to the reported information, Thomaston Mills appeared on a listing associated with the royal ransomware group on March 09, 2023. The available summary states that internal files were exfiltrated in a ransomware attack. No figure has been given for the number of people affected, and public detail does not describe the initial access method, the duration of any intrusion, the precise volume of data taken, or whether systems were encrypted in addition to the claimed theft of files.

Because the listing itself is a claim by the threat actor, the incident should be treated as asserted rather than independently verified in full. No dollar amounts, file counts, or direct quotes from the organisation beyond the background description of its business have been supplied in the facts. In short, the core known elements are the organisation’s name, the reported date, the attribution to royal, and the characterisation of the exposed material as internal files taken during a ransomware attack.

The group behind it: royal

Royal is a ransomware operation that became publicly visible in 2022 and has been associated with double-extortion tactics: encrypting systems while also stealing data and threatening to publish it if demands are not met. The group has typically relied on initial access through common vectors such as compromised credentials, phishing, or exploitation of exposed services, followed by lateral movement and data staging before ransomware deployment. Like other actors in this category, royal has used dedicated leak sites to name victims and, in some cases, to release samples or larger archives of stolen material.

In this instance, the group’s listing of Thomaston Mills constitutes a claim that the organisation was hit and that internal files were taken. No further statements attributed specifically to royal about this victim—such as ransom demands, deadlines, or detailed inventories of the stolen data—appear in the provided facts. Readers should therefore separate the group’s general, well-documented pattern of behaviour from the unconfirmed particulars of any single listing.

Who is Thomaston Mills?

Thomaston Mills was founded in 1899 by R.E. Hightower and is described as the oldest domestic sheet mill in the United States. It remained under Hightower family ownership until 2001 and has since been owned by the Zaslow family; together the two families represent more than two centuries of textile experience. The company continues to operate as a family business focused on manufacturing and distributing high-quality bed and bath linens to the hospitality, healthcare, and institutional markets. It finishes millions of yards of fabric each year at its bleachery in Easley.

Organisations of this type typically maintain customer and supplier records, employee information, production and logistics data, financial and contracting documents, and operational files tied to large institutional buyers. A breach affecting such a firm can therefore touch both commercial relationships and personal data held in the ordinary course of manufacturing and distribution. The consequential nature of an incident here stems less from consumer-facing retail volume and more from the sensitivity of business-to-business and workforce records that textile and hospitality-supply companies routinely process.

What was likely exposed

The facts name the exposed material as internal files exfiltrated in a ransomware attack. No further breakdown—such as whether the files included employee records, customer contracts, financial statements, or production data—has been disclosed. The number of individuals affected is unknown.

Companies in textile manufacturing and institutional linen supply commonly hold payroll and human-resources data, vendor and customer contact details, purchase orders, shipping and inventory information, and internal correspondence. It is reasonable to expect that some combination of these categories could be present among “internal files,” yet the exact contents remain unconfirmed. No specific data types beyond the general description of internal files should be treated as established fact for this incident.

Why it matters

For people whose information may have been among the exfiltrated files, the practical risks include targeted phishing, social-engineering attempts that reference real business relationships, and potential misuse of any personal or contact details that appear in internal documents. Employees, contractors, and contacts at hospitality or healthcare clients could face elevated scrutiny of unsolicited messages that appear to come from familiar partners.

For Thomaston Mills itself, the incident raises operational and reputational considerations: the need to investigate and contain any intrusion, to assess contractual and regulatory notification duties, and to manage relationships with institutional customers who may require assurance about supply-chain and data-handling practices. Because the scale and precise contents are undisclosed, the full extent of downstream impact cannot yet be measured from public information alone. Calm, evidence-based follow-up by the organisation and by potentially affected parties remains the appropriate response.

Were you affected?

If you have worked for, supplied, or done business with Thomaston Mills, monitor account statements and be cautious of unexpected emails or calls that reference the company or its customers. Consider changing passwords on related accounts, enabling multi-factor authentication where available, and watching for unusual activity. You can also run a free exposure scan of your email address to check whether your information has already surfaced in known breach data sets. Public detail on this incident remains limited; further clarity, if it emerges, should come from official notices rather than from unverified claims.
