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 202 public disclosures across our corpus. First observed on a leak site on June 1, 2021; most recent post May 8, 2026. The operation is currently active.
