1. Executive summary
The ransomware group tracked as qilin listed Revenga Smart Solutions, a Spanish company (gruporevenga.com), on its leak site on 2026-09-27. The listing is a claim of compromise published by the operator; no victim statement, sample, or independent forensic confirmation is available in the source material, and no CVE, exploited component, or initial access vector is named. The verified reference data holds no MITRE ATT&CK profile for qilin, so the attribution rests on the operator's own leak-site post and is unconfirmed. For EMEA financial services clients the exposure is third-party and supply-chain: any firm using Revenga Smart Solutions as a technology or services supplier should treat this as a potential data-theft and extortion event at that supplier until the company confirms otherwise.
2. Regulatory framing
| Article | Trigger (the fact in this item) | Practical impact |
|---|---|---|
| DORA Art. 28: ICT third-party risk — general principles | A named ICT supplier to the sector, Revenga Smart Solutions, has been listed by a ransomware operator. | Clients with a live contract with this supplier must assess the incident against their own third-party risk register and obtain a status position from the supplier. |
| DORA Art. 30: key contractual provisions with ICT third-party providers | The same supplier relationship. | The incident is the point at which contractual cooperation, notification and audit clauses with this provider are exercised, not merely reviewed. |
| NIS2 Art. 21(2)(d): supply chain security measures | The same supplier relationship. | Entities in scope must be able to show they hold and act on supply-chain security measures covering this provider. |
No DORA Art. 17, 18, 19, 24 or 29 obligation and no NIS2 Art. 23 or UK NIS 2018 duty is engaged by this item on the facts available: there is no confirmed incident at a client, no confirmed major incident, and no confirmed disruption to a client's own service. Those articles become live only if a client's own operations are affected or if the supplier confirms an incident that meets the client's own classification thresholds.
3. Technical analysis & attack chain
There is no attack chain to reconstruct. The source is a leak-site index entry, not an incident report. It records the group name (qilin), the victim name (Revenga Smart Solutions), the country (ES) and the victim website (www.gruporevenga.com). It does not state an initial access vector, an exploited CVE, a payload, a persistence mechanism, a command-and-control channel, a lateral movement path, a data volume, or a ransom demand. The page carries a placeholder field where a description would sit, and the only other content is a DNS record section and a leak screenshot placeholder, neither of which is populated in the material provided.
What can be said with confidence is limited to the listing itself. A leak-site post is an operator claim. It is not evidence that data was exfiltrated, that encryption occurred, or that the victim's production systems were affected. Operators have listed victims before encryption completes, and have listed victims whose data was never published. Treat the listing as a signal to verify, not as a confirmed breach.
Attribution is unconfirmed. The verified reference data contains no MITRE ATT&CK profile for qilin, so no TTP mapping, tooling set, or infrastructure pattern can be asserted here. Any statement that qilin uses a particular loader, encryptor, or initial access broker would be invention, and is not made.
Single-source caveat: everything in this section derives from one index page at ransomware.live. It is a single source and it is a secondary one. Verify before acting on it beyond the third-party risk steps in §4.
4. Mitigation & containment
P1 (within 24 hours)
- If Revenga Smart Solutions is a live supplier, contact your relationship owner there and ask directly whether they have an incident, whether client data is involved, and what their current service status is. Do not rely on the leak-site post as the answer.
- Identify every internal system, integration, or data flow that touches gruporevenga.com or any Revenga-hosted service. Record the data categories involved and whether any of it is client or personal data.
- If any Revenga-hosted service is reachable from your network, review outbound connections to it for the last 30 days for unusual volume or timing. A supplier compromise that has not yet been disclosed is the case where this matters.
- Confirm that any credentials, API keys, or service accounts shared with Revenga are inventoried and can be rotated on short notice. Do not rotate yet; establish that you can.
P2 (within 72 hours)
- Exercise the notification and cooperation clauses in the Revenga contract (DORA Art. 30 territory). Ask for a written status position with a date, not a verbal assurance.
- If Revenga confirms an incident affecting your data, run your own incident classification against DORA Art. 18 criteria and determine whether Art. 19 reporting to your competent authority is triggered. That determination is yours, not the supplier's.
- Review whether any other supplier in your estate depends on Revenga, directly or through a subcontractor. Concentration risk in a single mid-size supplier is the failure mode here.
P3 (within 7 days)
- Update the third-party risk register entry for Revenga with the listing date, the source, and the verification outcome.
- If the supplier does not respond or responds evasively, escalate to your procurement and legal functions and consider whether the contract's audit rights need to be invoked.
- No patch, version pin, or configuration change is available from this item. There is no CVE and no vendor fix to apply. Do not invent one.
5. Indicators of compromise
No indicators of compromise available in the source material. The source provides no hashes, domains, IP addresses, file paths, registry keys, or ransom-note text. The only network-identifiable value is the victim's own website, which is not an indicator of the threat and is not reproduced as one.
Behavioural indicators: none are described in the source. The listing records no authentication pattern, device registration, process activity, or network behaviour.
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 or paths, registry keys, ransom-note text, or hard-coded values. The only strings present are the group name, the victim name, and the victim's own domain, none of which are artefacts of the threat. A rule built on those would detect reporting about the incident, not the incident.

8. Adverse Trace position
We assess this as a low-confidence, single-source listing with no technical detail and no confirmed impact, and we are not raising it above that on the evidence available. The risk to EMEA financial services clients is indirect and sits in the supply chain: if Revenga Smart Solutions is in your estate, the listing is a trigger to verify, not a confirmed breach, and the DORA Art. 28 and Art. 30 obligations attach to the supplier relationship rather than to any incident at your own firm. Attribution to qilin is unconfirmed because the verified reference data holds no MITRE ATT&CK profile for that group, and we will not map TTPs to an actor we cannot profile. Adverse Trace will monitor the leak site for a data publication, a victim statement, or a Spanish or sector regulator notice, and will reissue this advisory if Revenga confirms an incident or if any technical artefact emerges that supports detection content. Clients who hold a Revenga contract should treat the P1 verification step as the action that matters today.
