Attack summary

Severity: high — Healthcare provider with sensitive patient data (psychiatric records, medical histories) across multiple facilities and age groups. Encryption of hospital systems disrupts critical care operations. Patient data is inherently regulated (GDPR, medical confidentiality). No explicit proof of exfiltration published, but operational impact and data sensitivity are substantial.

Ransomware operator claims to have encrypted Valisana's systems. The leak post does not explicitly state data exfiltration, but lists the victim alongside multiple confirmed data-breach victims in a consolidated disclosure catalogue.

What the group claims

Valisana! Verantwoordelijkheid is de morele nood om aan onze eigen handelingen of die van anderen te beantwoorden. Bij Valisana leggen we de nadruk op het belang van ieders verantwoordelijkheid, maar eveneens op gedeelde verantwoordelijkheid. Dit houdt betrokkenheid, zelfstandigheid, erkenning van de anderen en samenwerking in. Wij streven naar wederzijds respect binnen de therapeutische relatie alsook respect voor zichzelf en oprechtheid en duidelijkheid van het project. Respect is een institutionele waarde die zowel patiënten als professionelen betreft. Wij willen openstaan voor verscheidenheid aan culturen, innovaties en leerprocessen. Wij streven naar zorg op maat van de patiënt anders dan standaardoplossingen. Elke patiënt, zonder uitzondering of onderscheid, moet in functie van zijn behoeften op een rechtvaardige en neutrale wijze behandeld worden. Hetzelfde is van toepassing voor de teamleden. Wij moedigen iedereen aan om rechtuit te spreken en werken aan een open feedback cultuur. Wij streven met onze collega’s en patiënten naar een therapeutisch gerichte samenwerking zonder vooroordeel of a priori. We streven naar erkenning en integratie in al onze reflecties, acties en beslissingen, zowel de eigen inbreng van elk teamlid als de specificiteit van elk van onze patiënten.

Disclosure context

About Ransomhouse

Ransomhouse is a ransomware group that emerged in June 2021, operating primarily for financial gain through extortion campaigns targeting organizations across multiple sectors globally. The group's origin and specific affiliations remain unclear based on publicly available intelligence, though their operational patterns suggest they function as an independent cybercriminal organization rather than a traditional ransomware-as-a-service model. Ransomhouse employs double extortion tactics, stealing sensitive data before deploying their ransomware payload and threatening to publish the information on their leak site if victims refuse to pay the demanded ransom. The group has demonstrated a broad targeting approach, with documented attacks against 187 victims primarily concentrated in the United States, China, United Kingdom, Italy, and Spain, focusing heavily on healthcare, technology, business services, and manufacturing sectors. While specific high-profile campaigns have not been extensively documented by major security firms, the group's consistent victim count and geographic distribution indicate sustained operational capability since their emergence. As of current reporting, Ransomhouse remains active with no known major law enforcement disruptions or confirmed rebranding efforts. The group has been linked to 210 public disclosures across our corpus. First observed on a leak site on June 1, 2021; most recent post June 29, 2026. The operation is currently active.

If your organisation is affected

A listing by Ransomhouse means Valisana appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

  • Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
  • Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
  • Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
  • Report the incident to your national CERT, CERT.be (Belgium), as required for your jurisdiction.
  • Monitor for the data appearing on Ransomhouse's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
