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 Hong Kong College of Technology 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.
  • 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.
