About
Written by ThreatCluster from 4 storieskazu is a ransomware group that operates an extortion-based model built on data theft and threats to leak stolen files, including a case where it threatened to publish over 400,000 files within 48 hours. Victims span sectors such as Healthcare, Public Sector, Financial Services, Professional Services, and Technology, with activity reported across the United States, Mexico, Colombia, Brazil, and Canada. The reporting shows a pattern of data exfiltration followed by rapid ransom demands; for example, in the ManageMyHealth breach in New Zealand thousands of patients' records were exposed and a ransom of US$60,000 was demanded.
