## 1\. Executive summary

The ransomware group tracked as payload listed Marbre Design, a French processor of natural stone, marble, granite and composite materials, on its leak site on 2026-10-28\. The listing names the victim and country only; no data sample, file count, ransom demand or proof of exfiltration is visible in the indexed entry. Marbre Design is a manufacturing and installation business, not a financial services firm, so the direct exposure to EMEA financial clients is indirect: through supplier and facilities relationships, and through the possibility that stolen commercial records include contract, pricing or payment detail. No CVE, exploitation state or actor profile is available for this item, so the risk is assessed from the listing alone and should be treated as unconfirmed until the victim or the group publishes further detail.

## 2\. Regulatory framing

No specific DORA/NIS2 article is directly engaged by this item.

## 3\. Technical analysis & attack chain

The source material does not describe how the intrusion was carried out. The ransomware.live entry records only the group name (payload), the victim name (Marbre Design) and the victim's business profile. There is no stated initial access vector, no exploited component or CVE, no malware family, no persistence mechanism, no command-and-control detail and no confirmed exfiltration. The following is the extent of what the listing supports:

1. The group operating as payload posted Marbre Design to its leak site on 2026-10-28.
2. The listing identifies the victim as a French natural-stone processor that custom-manufactures countertops, bathroom fixtures, fireplace surrounds and interior architectural elements, with operations in precision cutting, slab polishing and on-site installation.
3. The entry carries a leak screenshot placeholder but no visible sample data in the indexed copy.

Everything beyond that is absent. The source does not state whether data was exfiltrated, how much, or whether encryption occurred. It does not name a ransom demand or a deadline. It does not link the listing to any prior campaign, tooling or affiliate.

Attribution caveat: the group name "payload" appears only in the ransomware.live index. No MITRE ATT&CK profile, no CISA advisory and no independent vendor reporting is available to corroborate the group's identity, its typical tooling or its targeting pattern. Treat the attribution as unconfirmed. The victim's own confirmation of an incident is also absent from the source; the listing is the sole claim that an intrusion occurred.

For a financial services reader, the practical relevance is supply chain. A stone fabricator sits in the facilities, premises and fit-out chain rather than the payments or core banking chain. The plausible data at risk in such a breach is commercial: purchase orders, invoices, bank details for supplier payments, site access records and staff personal data. None of that is confirmed by the source. It is the category of data a business of this profile would hold, and it is the reason a supplier relationship warrants a check rather than a dismissal.

## 4\. Mitigation & containment

P1 within 24 hours

- Confirm whether any EMEA financial client has an active supplier, facilities, fit-out or premises contract with Marbre Design. If so, ask the relationship owner whether Marbre Design has notified them of an incident, and record the answer. The listing is the only current signal; do not treat it as confirmed until the supplier responds.
- Where a contract exists, review what data the supplier holds on the client's behalf: invoices, bank account details, site access lists, staff contact records. If bank details for supplier payments sit with the supplier, verify them out of band against the client's own records before the next payment run.
- Add the supplier to the third-party watch list and flag any change in its banking details, remittance instructions or points of contact as requiring callback verification.

P2 within 72 hours

- If the supplier confirms an incident, invoke the contract's security and notification clauses and request the scope: what data, how much, whether exfiltration is confirmed, and what the supplier's recovery timeline is. Do not accept the leak-site listing as scope.
- Review recent invoices and payment instructions from the supplier for signs of tampering or substitution, particularly any change of bank account in the weeks before the listing.
- Where the supplier has on-site access, review physical access logs and any credentials or badges issued to its staff, and confirm they are still required.

P3 within 7 days

- Add supplier-held commercial records to the data inventory so future incidents of this kind can be scoped without a manual search.
- Where the client's third-party register does not already record which suppliers hold payment or personal data, add that field. A stone fabricator with invoice and bank detail access belongs on it.

No vendor fix, patch or version applies to this item. The source names no affected product or software.

## 5\. Indicators of compromise

No indicators of compromise available in the source material.

The source describes no observable behaviours beyond the leak-site listing itself. There are no hashes, domains, IP addresses, file paths, registry keys or command lines to publish. The only machine-pivotable artefact is the leak-site URL, which is a public index page rather than a malicious indicator and is cited in §7.

## 6\. Detection

Insufficient indicators to author detection rules.

The source contains no distinctive strings, command-line flags, mutex names, scheduled-task or service names, file names, registry keys, ransom-note text or hard-coded values. A rule built on the group name or the victim name would detect reporting about the event, not the threat, and is not emitted.

## 7\. Sources

- ransomware.live, "Ransomware: payload named Marbre Design", https://www.ransomware.live/id/TWFyYnJlIERlc2lnbkBwYXlsb2Fk, published 2026-10-28.
- ransomware.live, "Victim: Marbre Design – payload", https://www.ransomware.live/id/TWFyYnJlIERlc2lnbkBwYXlsb2Fk, published 2026-10-28\. Single source; the two entries are the same index record and do not independently corroborate each other.

## 8\. Adverse Trace position

Adverse Trace assesses this item as low direct severity for EMEA financial services clients and moderate supply chain relevance where a client holds a live supplier relationship with Marbre Design. The listing is single-sourced to ransomware.live, the group attribution to "payload" is unconfirmed against MITRE ATT&CK or any independent vendor report, and the source states no exfiltration, no encryption and no ransom demand. We will monitor the leak site for a data sample, a stated volume or a group statement that would raise the assessment, and we will update this advisory if Marbre Design or the group publishes confirmation. Clients with a supplier relationship should treat the P1 supplier verification as the immediate action and report back so we can scope the exposure.
