Frisby Roofing (Frisby Construction LLC) Listed by Medusalocker Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

A ransomware group known as Medusalocker has listed Frisby Roofing (Frisby Construction LLC) on its leak site, according to a public posting dated September 12, 2026. That listing is an unverified claim by the group. As of writing, the company has not publicly confirmed the claim. For customers, employees, suppliers, and others who may have dealt with a local residential roofing contractor, the practical question is straightforward: if personal or business information were ever involved, what should they watch for and what steps make sense.

Public detail remains limited. The number of people who might be affected is unknown, and the listing does not set out verified inventories of files. What follows treats the Medusalocker posting as a claim, explains what such listings typically mean, and outlines conditional steps people can take without treating the accusation as proven fact.

Inside the listing

On September 12, 2026, Medusalocker listed Frisby Roofing (Frisby Construction LLC) on its leak site. The available record frames the organization as a residential roofing contractor and supplies contact and operational background drawn from public-facing business information. Beyond the fact of the listing itself, the record does not disclose timing of any alleged intrusion, scale, method of access, ransom demands, or proof packages. People affected are listed as unknown. Data types named as exposed are not disclosed.

Leak-site listings of this kind are pressure tactics. Groups post a victim name and often threaten to publish material unless payment is made. A listing does not by itself establish that systems were compromised, that files left the organization, or that any particular dataset is authentic. Frisby Roofing (Frisby Construction LLC) has not publicly confirmed the claim as of writing. Readers should treat every specific assertion about this company as coming from the group’s claim unless independent confirmation appears.

The group behind it: Medusalocker

Medusalocker is a known ransomware operation that has appeared in public reporting for several years. Like other extortion-focused crews, it is associated with encrypting systems and pressuring organizations by threatening to release data on a dedicated leak site. Public accounts of the group describe affiliate-style activity, double-extortion messaging, and listings that name companies across multiple sectors. Those patterns are general background on the actor; they are not proof of what happened in any single case.

For this listing, the only incident-specific claim in the given record is that Medusalocker placed Frisby Roofing (Frisby Construction LLC) on its site on the reported date. The group’s broader reputation for leak-site pressure does not fill in missing details here. Method, entry path, dwell time, and whether any files were actually taken remain undisclosed in the material provided. The listing should be read as an unverified accusation intended to create urgency, not as a confirmed forensic report.

Who is Frisby Roofing (Frisby Construction LLC)?

Frisby Roofing operates as Frisby Construction LLC and is described in the available material as a family-owned, locally operated residential roofing contractor. Public business details associated with the firm include complete roof tear-off and replacement work, dimensional shingles from brands such as CertainTeed, Tamko Heritage, and GAF, and related services such as ice and water shield, flashing, ventilation, gutter aprons, and pipe boot flashing. Contact channels cited in the record include main and 24-7 phone lines, a showroom or office number, a sales email address, and a company website.

The same background notes suppliers and related parties such as QXO’s Cincinnati branch, Beacon Building Products, Mueller, NisbetBrower, The Patch Boys, Corken Steel, and McCabe Lumber, along with a subcontractor reference to BullDogg Home Repairs. Payroll tooling is noted as Paycor/PaySimpl. Firms in residential contracting routinely handle customer job files, estimates, invoices, scheduling, supplier accounts, and employee payroll information. A leak-site claim against such a business matters because those categories of records, if ever exposed, can affect homeowners, workers, and trade partners—not because any exposure has been independently established here.

What data was at risk

The facts state that data types named as exposed are not disclosed. It is therefore not possible to say from the public record what, if anything, was taken. Asserting a specific inventory would go beyond the listing and would treat attacker marketing as fact.

If files connected to a residential roofing contractor were ever obtained by a third party, organizations in this sector typically hold some mix of customer contact details, project addresses, contracts or work orders, payment or financing-related records, photos or job documentation, employee and payroll information, and supplier or subcontractor correspondence. Those are sector norms, not a claimed description of this incident. Exact contents remain unconfirmed. Any discussion of risk for Frisby Roofing (Frisby Construction LLC) must stay conditional on whether material was actually removed and what it contained—points the available listing does not settle.

What's at stake

For individuals, the stakes are practical rather than abstract. If customer or employee information were involved, risks could include unwanted contact, phishing that references a real roofing job or address, attempts to socially engineer payment or identity details, and longer-term misuse of static identifiers such as names, phone numbers, or emails. Payroll-related data, if ever exposed, can raise separate concerns around tax or direct-deposit fraud. None of that is established for this listing; it describes what people commonly face when contractor records surface in other, confirmed cases.

For the organization and its partners, a public extortion listing can create reputational pressure, customer questions, and operational distraction even when the underlying claim is unproven. Suppliers and subcontractors named in ordinary business relationships may also receive inquiries. A leak-site post does not prove negligence, poor controls, or a successful theft. It establishes only that a named group chose to publish an accusation. Until there is independent confirmation, the gap between claim and verified incident remains wide.

If your data was involved

If you have been a customer, employee, or partner of Frisby Roofing (Frisby Construction LLC) and you are concerned that your information might be implicated, treat the situation as conditional. Watch for unexpected messages that reference recent roofing work, invoices, or personal details you would only expect the company or its vendors to know. Prefer official channels you already trust when verifying any request for payment or data. Consider placing fraud alerts with major credit bureaus if you have reason to believe sensitive identity information could be at risk, and review bank and card statements for unfamiliar activity. Employees paid through common payroll platforms may wish to confirm that direct-deposit and tax details have not changed without their approval.

Preserve suspicious emails or texts rather than clicking links inside them. Update passwords on important accounts if you reuse credentials across services, and enable multi-factor authentication where available. Because this Medusalocker listing is unverified and the company has not publicly confirmed an incident as of writing, there is no established roster of affected individuals to check against. As a general precaution, readers can run a free exposure scan of their email to see whether their address has already appeared in other known breach datasets and then decide on further monitoring from there.
