Written by ThreatCluster from 19 stories

ransomhouse operates as a ransomware‑as‑a‑service group pursuing an extortion‑driven model, combining data theft with encryption and leveraging upgrades to multi‑layered encryption and dual‑extortion tactics. The group has claimed 139 victims, with the most affected sectors being Manufacturing, Business Services, Technology, Healthcare, and Public Sector, and the countries most frequently impacted are the United States, China, Japan, Brazil, and Spain. Recent reporting shows a pattern of targeting high‑value organizations with data exfiltration and ransom demands, as illustrated by the Nichirei Corp. attack in July 2026, where stolen confidential data was threatened with release. Incidents span manufacturing, e-commerce, and cultural sectors across Asia, Europe, and North America.
